2019 IMPACT REPORT

We founded Sunrun in 2007 with the vision to

create a planet run by the sun. What began as

graduate students building a company during

the Great Recession has grown to thousands of

employees and more than 285,000 customers

across the country.

Recent events have changed the way the

entire world is working, living, and thinking.

Resiliency and energy are more important now

than ever as we face wildfires, hurricanes, and

other natural disasters, alongside the risk from

pandemics like COVID-19. Yet these challenges

present opportunities that will make Sunrun

more durable. We are focused on employee

and customer health and safety, the health of

the company, and continuing to deliver value

to our customers. We’re quickly making the

process of installing solar almost completely

contact-free. We have already moved our sales

consultations from in-person to virtual, invested

in technology to streamline our installation

processes, including online permitting and

interconnection in many locations, and deployed

drone technology to complete rooftop surveys.

2019 IMPACT REPORT

In California, households are using as much as 20%

more electricity than normal. Home solar and batteries

not only give people peace of mind financially but, as

homes become sanctuaries, it allows them to safeguard

their families against the increasingly unreliable

electricity grid when they need power most.

Sunrun is committed to serving all stakeholders: our

employees, our customers, our financial partners,

and the communities in which we operate. To

ensure alignment with our mission, we created a

formal committee of senior management to oversee

Environmental, Social and Governance (ESG) matters

at the company, while also establishing board level

oversight of ESG performance by our Nominating &

Corporate Governance Committee. These steps build

on many actions we have taken over the years to be a

company that embraces all aspects of sustainability.

We are already deeply carbon negative, and seek

to help our customers and partners become carbon

negative as well. Our solar systems have prevented

greenhouse gas (GHG) emissions totaling 5.2 million

metric tons of carbon dioxide equivalent (CO 2 e). Our

goal is to replace fossil fuel plants one at a time, and

the choices we’re making as a company are getting us

a little closer to this goal every year.

We are also a financially sustainable company. In

2019, we grew our customer base by 22% while

generating $102 million in cash, after adjusting for

certain activities. This strong financial foundation and

attractive ongoing margins supports continued growth

and innovation.

We will continue delivering our critical home solar and

battery service to customers safely. In the decade

ahead, we look forward to continuing to provide clean,

resilient energy to people across the nation.

Financial Sustainability Sunrun has delivered robust growth over its 13-year

history and aims to generate strong returns to our

financial partners while building a solid financial

foundation that allows the company to make a

meaningful impact for decades to come. Financial

sustainability is core to the company’s philosophy.

Our operating and financial performance highlights

our discipline and commitment to sustainability. In

2019, we grew our number of customers by 22% while

maintaining strong unit economics that allowed us

to generate $102 million in cash, without relying on

common equity issuances or raising additional

recourse debt. We believe that strong net unit margins

provide Sunrun a foundation to be able to continue to

grow, innovate, and serve all stakeholders, including

our stockholders and financial partners.

We have $5 billion of gross solar system assets on

our balance sheet and have largely funded our growth

with non-recourse project debt and tax equity. Sunrun

2019 IMPACT REPORT | VISION AND VALUES

Sunrun’s Environmental Impact

At Sunrun, we offer clean, reliable, affordable solar

energy and battery storage solutions to accelerate

the transition away from polluting fossil fuels.

We recognize that inaction on climate change

threatens global security and stability, and bringing

solutions to bear on the issue remains the driving

force behind our mission to create a planet run by

the sun. Sunrun is committed to comprehensive

environmental stewardship as demonstrated

through the following avenues:

Supplier Responsibility Sunrun vendors are subject to screening on environmental and social

criteria. Please refer to our Vendor Code of Conduct

for more information on the policy and our “Vendor

Sustainability” section below for 2019 updates.

Resource Efficiency and Pollution Prevention Sunrun is reducing or eliminating hazardous

waste release, reducing waste generation, limiting

greenhouse gas emissions, and engaging in product

end-of-life stewardship.

Performance Evaluation and Reporting We monitor performance and report in accordance

with prevailing sustainability reporting frameworks,

such as the Sustainability Accounting Standards

Board (SASB) and Global Reporting Initiative

(GRI). Our annual reporting informs interested

stakeholders on environmental performance, and

helps identify priority areas for improvement.

Employee Awareness Employees are provided with opportunities to develop environmental

knowledge and skills, empowering them to lessen

their personal carbon footprint.

2019 IMPACT REPORT

Sunrun’s Climate Change Strategy

Sunrun exists to accelerate the transition to a low-carbon, climate-resilient economy. However, we must appreciate

that climate risks, which could disrupt or compromise our operations, are real today and will persist. Only through

tireless efforts to deploy our products and services and to adhere to our evolving environmental and social policies

can we insulate ourselves, our partners, and our communities from the consequences of unchecked climate change.

Reducing GHG Emissions

Sunrun’s solar energy systems offset GHG emissions every moment that they deliver clean energy to our customers.

During 2019, we deployed 413 megawatts of solar to 53,900 customers. These systems could generate nearly 16

billion kilowatt-hours of clean energy during the next 30 years, enough to prevent the emission of nearly 11 million

metric tons of CO 2 e. This quantity is more than 33 times greater than the quantity of CO

2 e emitted to deploy these

systems, which means that Sunrun negates significantly more emissions than we produce.

Sunrun’s GHG emissions estimates draw on the guidance provided in the GHG Protocol Corporate Standard.1 Our

emissions inventory includes direct (scope 1), indirect (scope 2), and other indirect (scope 3) emissions, covering

emissions attributable to Sunrun’s company-owned and -operated vehicle fleet, occupied offices and warehouse

space, equipment-lifecycle considerations, and the supporting activities of our partners. We prepared our first

emissions inventory in 2017 and replicated the same methodology in subsequent years so results can be compared

readily. Please refer to the Appendix for more details about on our calculations and underlying assumptions.

Emissions Intensity Energy Intensity*

Positive Carbon Returns

Once Sunrun’s solar energy systems begin operating, positive carbon returns accrue rapidly. Our deployed solar

energy systems prevent more GHG emissions than they emit over their product lifecycle, resulting in a net-positive

carbon balance. After operating for just 10 months, a Sunrun solar energy system will prevent the emission of as

much GHGs as were emitted to create and install the system. Because Sunrun’s systems are expected to produce

clean energy for 30 years or longer, our systems prevent the release of harmful GHGs for 97% of their lifetime.

emissions over 30 years.

For each metric ton of CO 2 e that Sunrun

emitted in 2019, the solar energy systems

that Sunrun deployed in 2019 are

expected to prevent more than

33 metric tons of CO 2 e emissions

over 30 years.

For each metric ton of CO 2 e

emitted by Sunrun in 2019, our

entire fleet of solar energy systems

has already prevented more than

16 metric tons of CO 2 e emissions

from entering the atmosphere.

Preserving Clean Air and Water

Solar energy prevents emissions of nitrogen oxides, sulfur oxides, methane, and ozone that result from the

combustion of fossil fuels. The electricity produced by systems that Sunrun deployed in 2019 will meaningfully

reduce these harmful pollutants by lowering households’ consumption of fossil-fuel electricity. In addition,

solar and other renewable sources of electricity emit fewer GHG emissions per kilowatt-hour during their lifecycles

than fossil fuels.2,3

In addition to preventing the release of air pollutants, Sunrun solar and battery systems do not consume large

amounts of freshwater like fossil-fuel power plants. Cooling traditional power plants requires the withdrawal of more

freshwater reserves than any other activity. Solar energy production helps lessen this freshwater consumption by

reducing the use of energy from thermoelectric sources.

2019 IMPACT REPORT | ENVIRONMENTAL IMPACT

Environmental Management System Sunrun strives for exceptional environmental performance, and maintains an environmental management system

(EMS) based on principles of continuous improvement. Our EMS is continually improved to remain aligned with

Sunrun’s business strategy and to ensure progressive environmental performance over time.

Vehicle Fleet We continually strive for environmental responsibility at Sunrun, including how we manage our vehicle fleet. In 2019,

we continued retiring gasoline vehicles in favor of hybrid and electric vehicles. Currently, nearly 50% of our vehicle

fleet is hybrid, and we expect this number to continue increasing throughout 2020 and beyond. Additionally, in 2019

we added real-time monitoring to our vehicle fleet in telematics solutions, providing opportunities to track drivers,

optimize route patterns that result in enhanced safety, and reduced emissions and operating costs.

Facilities We promote employee wellbeing and minimize negative environmental impacts across all of our facilities. From

the coatings and carpet we use to our extensive preventative maintenance policies, we continually search for

opportunities to reduce our carbon footprint. In 2019, Sunrun relocated both our Denver and San Francisco corporate

headquarters to LEED certified buildings.

Equipment Recycling As we deploy more systems, we also bear a greater responsibility for managing the end of the systems’ useful lives.

We are integrating product end-of-life considerations into our EMS and are preparing to decommission, recycle,

resell, or redeploy our energy systems. Sunrun uses monocrystalline and multicrystalline photovoltaic modules,

thereby avoiding the mounting concerns about hazardous materials present in alternative chemistries such as thin-

film modules. We are prepared to sustainably dispose of modules, batteries, inverters, and other electronic equipment

used in installations through partnerships with third-party recycling and refurbishment vendors. These vendors are

certified under the Responsible Recyclers R2:2013, OHSAS 1800:2007, and ISO 14001:2007 standards. Learn more

about the industry’s approach to lifecycle considerations from the Solar Industry Energy Association (SEIA).

Vendor Sustainability Sunrun works with vendors that share our commitment to creating a better, greener, and kinder planet. That’s

why we advocate to include policies on environmental protection and sustainability as well as responsible mineral

sourcing in our first Vendor Code of Conduct, adopted in January 2019. All of Sunrun’s relevant vendors are required

to sign our Vendor Code of Conduct, and in 2019, there were no known violations of the agreement.

Responsible Mineral Sourcing Sunrun expects its vendors to provide our company with products that contain responsibly-sourced commodities.

Vendors that supply products containing minerals (including but not limited to: cobalt, wolframite [titanium],

cassiterite [tin], tungsten, and gold) sourced from conflict-affected and high-risk areas must ensure that the

sourcing of these minerals does not knowingly contribute, directly or indirectly, to armed conflict, including terrorist

financing or human-rights violations. Sunrun expects vendors to source minerals in a manner consistent with the

Organization for Economic Cooperation and Development’s (OECD) Due Diligence Guidance for Responsible Supply

Chains of Minerals from Conflict-Affected and High-Risk Areas.

Sunrun recognizes that cobalt, a mineral used in some types of batteries, presents an increased risk of being sourced

from areas associated with unfair labor practices. Because of this, we choose to work with battery manufacturers

that share our commitment to responsible mineral sourcing. Additionally, Sunrun will evaluate battery innovations

that may further reduce the mineral content of batteries.

Sunrun’s Societal Impact

The Workplace A Culture of Safety

Sunrun believes access to a healthy and

safe workplace is a fundamental human

right. Ensuring the safety of Sunrunners, our

customers, and local communities is Sunrun’s

top priority, and we provide best in class training

and tools for our employees. The backbone of a

strong safety culture is two-way trust between

employees and their employer. A key indicator of

increased trust is employees feeling comfortable

reporting unsafe conditions and “near-miss”

incidents. In 2019, we saw an increase in these

reports, which we view as an encouraging sign

of increased trust.

This trust is demonstrated clearly in the

improvement seen in tracked safety metrics

year-over-year. The reduction of incidents in

2019 is directly attributable to field leadership

taking an active role in reducing repeat

accidents, ensuring immediate reporting, and

correcting unsafe conditions.

16

2019 IMPACT REPORT

Comprehensive safety training and certification programs also play a vital role in promoting safety across our

organization. Sunrun provides safety training programs for all OSHA-required safety topics and additional topics

specific to Sunrun for new hires. These trainings continue as employees mature in their roles. Two full days of training

are provided to new solar installers, electricians, and site assessors before they can participate in an installation, with

installers receiving an average of 40 hours of documented training by the end of their first year of employment.

FIGURE 13

Recordable Incident Rates (2016–2019)

Compared to similar industries, like roofing, electrical, and construction, Sunrun’s incident rates are currently lower

than all averages and continue to decline annually. Our minor injuries have dropped year over year while support for

injured workers increased and repeat incidents have decreased.

Our internal training programs are further strengthened by external certification and licensing agencies including

journeyman and master electrician license holders, Certified Safety Professionals (CSP) through the Board of

Certified Safety Professionals (BCSP), PV installation certifications from the North American Board of Certified

Energy Practitioner (NABCEP) and OSHA 30 cardholders. All construction supervisors and foremen maintain

CPR certification.

2019 IMPACT REPORT | SOCIETAL IMPACT

Verification and Compliance

Compliance with safety policies is achieved through vehicle monitoring, frequent inspections, and auditing of

quality-assurance (QA) photographs. The telematics devices in each of our fleet vehicles constantly transmit data

on speed, driving behavior, and location, allowing for targeted training on vehicle safety to employees. 100% of

installs are audited for safety through photo documentation, ensuring our work is performed to Sunrun’s safety

and quality standards. Additionally, random job-site and facility audits are performed to verify compliance and

training comprehension.

Product Safety

Sunrun’s Safety and Logistics departments collaborate on the selection of all new products. When a new chemical is

considered for use in field, office, or warehouse environments, Sunrun first evaluates the health and environmental

hazards documented on the safety data sheet published by the chemical’s manufacturer. Only products that can be

safely handled with basic personal protective equipment are accepted for use by Sunrun employees.

Vendor Health and Safety

Our commitment to ensuring safe and injury-free workplaces extends to our vendors. Sunrun’s Vendor Code

of Conduct requires that all vendors provide workers with a safe and healthy work environment. We require

vendors to comply with all applicable health and safety laws, regulations, and practices, including those relating

to occupational safety, emergency preparedness, occupational injury and illness, industrial hygiene, physically

demanding work, machine safeguarding, sanitation, food, and housing. We also require vendors to ensure that all

required permits, licenses, and registrations are obtained, maintained, and kept up-to-date and that all workers are

qualified and equipped to perform activities safely and responsibly.

To ensure that vendors abide by Sunrun’s Vendor Code of Conduct and applicable laws and regulations, we may

conduct periodic vendor audits. When an audit uncovers a violation, Sunrun reserves the right to terminate its

relationship with the vendor and impose restrictions on future business unless the violation is promptly corrected.

Sunrun aims to survey vendors that comprise at least 80% of total value transacted with Sunrun, along with new

vendors, to seek confirmations that each vendor is aware of and compliant with the Vendor Code of Conduct.

2019 IMPACT REPORT | SOCIETAL IMPACT

People and Communities As part of Sunrun’s efforts to increase diversity and inclusion, this year Lynn Jurich became the first CEO in the solar

industry to sign both the CEO Action for Diversity & Inclusion and the Catalyst CEO Champions for Change pledges.

These commitments will help Sunrun and other member companies achieve their goal of modeling best practices

in gender equality, diversity and inclusion. Catalyst recently released a report that showed an increase in women’s

representation from their member companies in the past five years.

Women make up 50% of our senior management team, and 43% of our Board of Directors. In 2018 we were the first

national solar company to achieve 100% pay parity after committing to The White House Equal Pay Pledge in 2016.

Sunrun’s six employee resource groups foster a culture of inclusion and belonging. The groups include Sunrun Women’s Network, Blacks & Allies, Latinx & Allies,

Asians & Allies, LGBTQ & Allies, and Veterans & Allies.

Sunrun Women’s Network Celebrating International Women’s Day and

Women’s History Month in March is important at Sunrun. For the 2019 International

Women’s Day theme, #balanceforbetter, our female executives provided excellent

insights into being a working mother with a demanding job. They encouraged

everyone to accept career challenges while constantly recommitting to their values,

both personal and professional.

Blacks & Allies Initiatives For the first time, Sunrun participated in the National

Black MBA Conference and Career Fair, gathering 10,000 undergraduates and

graduates each year seeking opportunities in sales, corporate functions and

operations. In partnership with Blacks & Allies and Sunrun’s Talent Acquisition

team, this helped us hire top diverse talent.

Latinx & Allies Initiatives This Spring, Sunrun became a supporter of the DIY

Invent Girls program, furthering our mission to make solar more inclusive and

inspiring young girls to go into STEM careers in the clean energy industry.

Asians & Allies Initiatives To celebrate Asian Pacific American Heritage Month,

Sunrun partnered with Catalyst to provide a webinar featuring talent from Asian

Pacific descent. Klinton Miyao, our Vice President of Legal, and inspiring speakers

from other industries shared how they dealt with bias and achieved success.

LGBTQ+ & Allies Initiatives To commemorate the 50th anniversary of the

Stonewall uprising, the Sunrun LGBTQ+ Employee Resource Group organized a

panel discussion with members of the LGBTQ+ community and allies who shared

their experiences. The focus was on creating safe spaces where everyone brings

Diversity Policy and Strategies Sunrun’s mission to create a planet run by the sun relies on making solar inclusive. To do so, we collaboratively

orient work around three pillars: the workforce, the workplace, and the marketplace.

Workforce

• We are proud to be an equal opportunity employer and a welcoming place for everyone without consideration of race, color, religion, ethnicity, citizenship, political activity or affiliation, marital status, age, national origin, ancestry, disability, veteran status, sexual orientation, gender identity, gender expression, sex or gender, or any other basis protected by law.

• We seek to attract, develop, advance and retain the best diverse talent through the use of job boards and paid campaigns. We attend events like Black MBA Conferences to ensure we are hiring diverse, high quality candidates.

• We focus on hiring underrepresented groups across all functions and managerial levels.

• We work with groups like GRID Alternatives and Blacks in Green to help reach and recruit individuals who are traditionally underrepresented in the solar industry, including women and people of color.

PAY PARITY AT SUNRUN

“Equal pay is about fair compensation for work performance and improving

the quality of life for employees and their families,” said Jeanna Steele,

Sunrun General Counsel and appointed member of the California Pay Equity

Task Force.

At Sunrun, we believe achieving pay parity is a significant step toward gender

equality in the workplace. Sunrun became the first national solar company to

achieve this milestone after committing to The White House Equal Pay Pledge

in 2016 under the Obama Administration. In 2018, Sunrun achieved 100% pay

parity for its employees, regardless of gender, who perform similar work in

similar locations across the United States.

Sunrun achieved its pay parity goal by committing to key principles:

• Completing a comprehensive annual review of compensation practices across the business with the help of an outside law firm.

• Voluntarily adopting a policy prohibiting inquiries into a candidate’s salary history.

• Providing equal paid parental leave for both male and female employees.

On April 1, 2019, Sunrun took the California Equal Pay Pledge developed

as part of the partnership between the California Commission on the Status

of Women and Girls and the Office of California First Partner Jennifer

Siebel Newsom. Sunrun’s commitment ensures that all employees are

fairly compensated and this creates a more inclusive and equitable work

environment for everyone.

Workplace

• We strive to create an open and inclusive culture where everyone’s unique backgrounds, thoughts, experiences and abilities are welcomed, valued, respected and celebrated.

• With the sponsorship of our executives, we leverage our Employee Resource Groups (ERGs) to create and sustain a workplace where everyone belongs.

• We utilize the results of internal surveys to better identify and address any diversity concerns and improve Sunrun’s processes.

Marketplace

• We plan to continue driving profitable growth by making solar and batteries more accessible to all, including people in low-income communities.

• On July 18, 2019 Sunrun won a contract with East Bay Community Energy to install solar and batteries on 500 low-income housing units in Oakland, California. The new solar paired storage resources will help offset the power generated from a retiring jet-fuel power plant in Jack London Square.

Employee Satisfaction and Development We want to make Sunrun an exceptional place to work and are committed to providing fair and equal pay to all

employees. To measure employee engagement and satisfaction, we conduct a company-wide survey twice a year.

Responses are anonymous to encourage employees to provide honest, candid feedback.

We believe that employee development and performance should be discussed between managers and their

employees regularly. As such, Sunrun’s “Check-Ins” program is scheduled for all employees three times per year.

These discussions focus on skill development, past contributions, and reflection of Sunrun values. Check-Ins are

purposefully separated from an annual compensation discussion to allow for an open discussion on areas for growth

and career development.

Recognitions

Sunrun won 11 awards based on employee survey data, and Lynn Jurich was recognized as one of the best CEOs in

the United States in 2019. These awards from Comparably are especially impressive because we were up against

many other companies including Microsoft, Google, LinkedIn, Costco, T-Mobile, and Amazon.

Training

Product training and the customer journey is a big focus at Sunrun. Therefore, we provide learning resources that

prepare our employees to provide positive experiences and results. We offer training for all employees in the areas of

new hire orientation, skill development, and leadership training for managers.

We have a robust library of online curriculum including electronic learning modules from third parties, as well as over

200 custom, in-house-developed eMods. The modules range from 2-minute “how to” videos to complex,

multi-hour training programs. Employees spent over 10,000 person-hours completing online learning in 2019.

Our skill-based employees take advantage of classroom training, hands-on training, and distance learning in the

form of webinars. We delivered 529 days of instructor-led training in 2019.

Online Resources

LinkedIn Learning is an on-demand learning solution designed to provide our employees with the tools to take

charge of their development, gain new skills and advance their current role and overall careers.

Since April 2019, Sunrun had 633 active users on LinkedIn Learning who have logged more than 1,110 total hours

developing their skills. The portal averaged 2 hours and 51 minutes per viewer.

Sunrun CEO Lynn Jurich was number 10 on

Comparably’s list of Best CEOs, and the only woman

recognized in their top 15. This serves as a reminder

that as a country we have much more work to do to

increase representation. In addition to the Comparably

award, Lynn recently received a Women Worth

Watching Award by Profiles in Diversity Journal,

recognizing her efforts to advance diversity and

inclusion. Past recipients include Mary Barra, CEO

of General Motors, Lynne Doughtie, CEO of KPMG,

and Marillyn Hewson, CEO of Lockheed Martin.

2019 IMPACT REPORT | SOCIETAL IMPACT

The Customer Community Since 2007, Sunrun has offset nearly 5.2 million metric tons of carbon dioxide by deploying 1,987 megawatts of solar

power. With a total of 285,000 customers, we see a new system installed every two minutes. This has created has

created hundreds of millions of dollars in savings for our customers, who see an average bill savings of 10-40% over the

lifetime of their system.

Brightbox has become a major focal point for the company, both in terms of energy services and customer experience.

Now, more than 15% of all Sunrun customers choose to add a Brightbox to their system. The resiliency, protection

during outages, and bill savings are clear values to customers across the country.

Permitting Efficiency

In 2018, Sunrun began working on the Solar Automated Permit Processing (SolarAPP) Campaign. SolarAPP is a

collaborative effort to foster residential solar adoption by making it easier for cities, counties, and utilities to quickly

and safely approve residential solar projects for installation and operation with the grid.

The first SolarAPP project kicked off in 2019, led by the National Renewable Energy Laboratory (NREL), which is

working with an all-star team of experts to build an online permit platform that will enable automated compliance

reviews and instant permit approval. This team includes solar industry groups, cities and counties, code bodies,

environmental organizations, and government entities.

• External soft costs, delays and resulting cancellations can add $1 per watt (or $7,000) per project for solar customers

• Every week shaved off external processes can increase the rate of local installations by up to 10%

24

2019 IMPACT REPORT | SOCIETAL IMPACT

When rooftop solar installation blockers are removed, customers are happier, realization rates improve, and adoption

rates go up. In turn, cities and counties benefit from greater community resilience and a higher volume of permitting

fees. When available, the SolarAPP portal will:

• Be free for organizations to adopt as needed

• Standardize permit applications and perform automated compliance checks based on code year and certification

• Enable instant permit approval, online fee payment, and digital record tracking

• Be able to stand alone or interact with various existing government and inspection platforms

• Ensure that city and county manual design review and inspection resources are only used on installations

• Eventually expand to more renewable energy and smart home technologies like battery storage and EV chargers

• Incorporate a marketplace of resources and training from code bodies and expert organizations

Early testing of the SolarAPP model in Nevada reduced wait timelines for installs and activation from over a month

down to zero days. This has allowed Nevada teams to set clear expectations with customers, ultimately ensuring a

better solar experience.

25

2019 IMPACT REPORT | SOCIETAL IMPACT

Our Global Society Beyond ensuring that our customers and employees are well cared for, Sunrun is committed to making an impact

on society as a whole. We do this through our industry-leading work in thought leadership, policy development, and

innovative energy networking programs.

Advancements in Thought Leadership

Putting panels on rooftops and batteries in garages is what we do on a daily basis. However, that is not our business.

Our business is building a future of resilience and sustainability. Our Energy Services team is on the cutting-edge

of energy technology and continually pushes the innovation envelope. We engage in partnerships that help create

distributed energy communities, outline plans to bring connected energy networks to life, and author concept

papers to share our vision with the world. Simply put, we’re trying to retire fossil fuel power plants one at a time and

create a healthier environment for future generations.

In 2019, we authored three pivotal pieces of thought leadership which set the stage for future action.

We Can Decarbonize Rapidly

Our climate is changing. Not only is it happening faster than expected, but extreme weather events

are destroying the very electric grid we rely on. According to the Intergovernmental Panel on Climate

Change (IPCC), we only have about 12 years to act before the damage is irrevocable. In her paper “We Can

Decarbonize Rapidly,” Lynn Jurich writes about the technology and solutions to decarbonize our electricity

system, and points to overwhelming public support as the catalyst to get us there. Lynn outlines the value of

prototyping, and focuses on how we can empower local resources to accelerates our efforts, recognizing that

much of our ability to decarbonize will depend on local efforts.

We should boldly scale local energy resources, and prove out how they can complement and streamline

our centralized power plants and transmission system. This will help us develop a reliable, affordable and

decarbonized energy system on a timeline that supports a prosperous and sustainable future.

Building a More Resilient Grid

Over the past 40 years, fire seasons have grown significantly longer and large fires are five times more

common. Higher temperatures and prolonged dry weather are testing our existing energy infrastructure and

threatening our environment. Too much energy flowing through power lines can result in sagging, which can

cause electrical sparks that lead to fires if this brings the line close to other objects, like trees. Sunrun’s paper

“Building a More Resilient Grid” outlines how rooftop solar and batteries can reduce the amount of electricity

that needs to be transmitted to a neighborhood, thereby mitigating risks associated with sending high

amounts of energy over power lines.

Repowering Clean

Local power can be the solution to the City of Los Angeles’ plan to phase out three natural-gas power plants.

The Los Angeles Department of Water and Power (LADWP) can access clean, reliable energy resources by

harnessing home solar to create a city-wide “virtual power plant.” Our analysis shows that rooftop solar and

batteries sited at 75,000 Los Angeles homes and apartment buildings can replace the peak capacity of one of

LADWP’s retiring gas plants for $60 million less than the construction of a new plant.

Going forward, Sunrun will continue paving the way for product developments and grid infrastructure impacts

through pilot projects, thought leadership, and prototyping of new energy concepts. We are partnering on

modernizing the grid, bringing home batteries to low-income communities, and continually developing

advanced products to improve the grid.

2019 IMPACT REPORT | SOCIETAL IMPACT

Spotlight on Outages This past year, millions of Californians were without electricity—for hours or

days—as utilities shut down power lines to prevent fires. In Northern California,

for instance, PG&E’s aging equipment has caused more than 1,500 fires,

including the state’s deadliest, over the last six years. And the utility tells

regulators that power shutoffs to prevent wildfires can be expected for the

next 10 years. Extreme weather events are expected to increasingly disrupt

our nation’s aging energy system. The United States suffers from the highest

number of power outages in the developed world and will need to spend

$2.2 trillion on infrastructure upgrades over the next two decades to solve

this problem.

Rooftop solar energy paired with batteries enables households to generate

power where it i’s used, reducing the effects of outages and providing reliable

backup energy when the grid fails.

In a sampling of Bay Area counties served by PG&E which experienced power

outages in October 2019, Sunrun customers were able to endure these outages

by utilizing rooftop solar and battery storage, many for days at a time, until grid

electricity was restored. Brightbox customers kept their lights on while the grid

was down for more than 36 hours on average in this time period.

County by county, this snapshot of Brightbox’s performance during recent power

outages in the Bay Area demonstrates the reliability and resilience afforded by

rooftop solar and battery storage to households.

1. SONOMA COUNTY The average Sunrun customer utilized backup electricity from their solar and battery system for 67 hours. One Santa Rosa family powered their essential home needs using rooftop solar and battery storage for 143 hours—nearly six straight days.

2. NAPA COUNTY The average Sunrun customer utilized backup electricity from their solar and battery systems for 53 hours. One Napa customer powered their essential home needs using rooftop solar and battery storage for 125 hours—more than five days.

3. MARIN COUNTY The average Sunrun customer utilized backup electricity from their solar and battery system for 54 hours.

4. SAN MATEO COUNTY The average Sunrun customer utilized backup electricity from their solar and battery system for 37 hours.

5. ALAMEDA COUNTY The average Sunrun customer utilized backup electricity from their solar and battery system for 28 hours.

6. SANTA CLARA COUNTY The average Sunrun customer utilized backup electricity from their solar and battery system for 24 hours.

7. CONTRA COSTA COUNTY The average Sunrun customer utilized backup electricity from their solar and battery system for 22 hours.

8. SOLANO COUNTY The average Sunrun customer utilized backup electricity from their solar and battery system for 21 hours. One Solano customer powered their essential home needs using rooftop solar and battery storage for 108 hours—more than four days.

Advancements in Connected Energy Networks

In 2019, Sunrun made major strategic advancements in connected energy networks through the development of

several distinct programs across the country.

ISO-NE

In February 2019, Sunrun won a bid to provide 20 megawatts of residential solar and battery power to the

ISO-NE wholesale capacity market. The capacity market auction determines what generating resources

will be selected - and at what cost - to help power the electricity system across the six New England states,

one of the most populated regions in the country. Sunrun’s awarded contract signifies the first time that

customer-sited solar and battery systems were selected to participate in a capacity market in the United

States, competing head-to-head with traditional, centralized power plants in a wholesale market.

HECO-VPP

In partnership with Open Access Technology International (OATI), Sunrun committed to participate in

HECO’s Grid Services Program on the island of Oahu. Between the years 2020-2024, Sunrun Brightbox

systems will provide stored solar power back onto the electricity grid during peak hours. More distributed

energy means less need for additional utility generation during times of peak energy demand. Sunrun’s

Brightbox batteries will also be discharged back onto the electricity grid to provide energy stability and

protect against blackouts during periods of underfrequency. Approximately 1,000 Brightboxes will be

enrolled in the initial program.

Glendale, California

In July 2019, Glendale’s City Council unanimously approved Glendale Water & Power’s plan, as proposed by

Sunrun, to replace the Grayson gas plant with local clean energy, including a “virtual power plant” made up

of residential solar and batteries. While this is not a final contract, the vote gives the utility the green light

to proceed with negotiations to secure these clean energy resources.

East Bay Community Energy

In 2019, Sunrun won a contract with East Bay Community Energy (EBCE) in Oakland, California to

provide 500 kilowatts of power from home solar and battery systems installed in Alameda County. This

contract utilizes California’s Solar on Multifamily Affordable Housing (SOMAH) program and the Self-

Generated Incentive Program (SGIP), helping low income families save money every month on their utility

bills, providing backup power through battery storage, and contributing to workforce development for

disadvantaged communities. Ultimately, the partnership with EBCE has a twofold benefit: It provides

resource adequacy for the entire grid by providing backup power, helping to retire a local jet-fueled power

plant, while also providing customer value streams through resilience and bill savings.

2019 IMPACT REPORT | SOCIETAL IMPACT

Advancements in Policy

In November, the Intergovernmental Panel on Climate Change released a report that found that global human-

caused carbon emissions must reach “net zero” by 2050 in order to limit temperature rise to 1.5 degrees Celsius.

This is no longer theoretical; in 2019, California’s largest utility went bankrupt due to liability from increasingly

catastrophic fire seasons that are destroying entire communities and forcing lengthy blackouts for millions. Globally,

we’re all witness to historic wildfires, torrential storms, and record-breaking temperatures.

It’s clear that reaching the climate apex is not an “if ” but a “when.” Although we need to adapt to a changed, and

changing, environment, there are mitigation steps we can take to protect our nation’s safety, economy and future.

If we wait longer to act on climate, it will be too late. We need policies today that give us a lifeline to escape the

climate crisis.

Home solar and batteries are changing how people experience energy. In particular, Sunrun’s policy team has seen

many positive outcomes after advocating for fair compensation for excess solar energy that is sold back to the grid,

programs that create connected energy networks using solar and batteries, and expanded access to solar and

batteries for low income and disadvantaged communities. The team also continued its work leading local, regional,

and national solar advocates organizing to help achieve key policy outcomes.

CA S E ST U DY

Compensation Net Energy Metering: In 2014, South Carolina passed Act 236, which legalized net energy metering (NEM) and third-party-owned

solar, but also put an arbitrary cap on how much would be allowed.

Those caps were rapidly approaching in 2019. Without policies

in place that encourages households to put solar panels on their

rooftops, home solar would wither in the state.

To prevent this, Sunrun played a critical role in a coalition of key

stakeholders, such as solar industry advocates, environmental

groups, and other solar companies, to fight for market-saving

legislation. This led to the introduction of the Energy Freedom Act,

which eliminates the NEM cap and encourages low-cost, competitive

options for clean energy in the state—like home solar sold by

companies such as Sunrun. It also protects thousands of solar

employees who would have otherwise lost their jobs, as no more solar

could be installed once the NEM cap was hit. This year, the Energy

Freedom Act was unanimously passed in South Carolina, a state with

a Republican-led legislature, and signed by the Republican Governor.

This was a huge milestone, not only by making sure that NEM was

protected, but also by empowering customers to continue taking

control of their energy production. Some ratepayers were stuck

paying an average of $27 a month on their energy bills for two nuclear

reactors that never produced any electricity. Rooftop solar can provide

an alternative for many people looking to control their power bills.

Accessibility

ConnectedSolutions: In Massachusetts, Sunrun successfully worked with policymakers and the state’s largest investor-owned

utility, National Grid, to build out a Bring-Your-Own-Device (BYOD)

program titled “ConnectedSolutions” in which ratepayers reduce

stress on the electrical grid during times of high energy demand in

the region. This is done by harnessing the collective energy from

home energy assets like batteries powered by clean solar energy.

Sunrun then provides the power from this network to utilities as

a type of “Virtual Power Plant.” We push energy from the solar-

powered batteries during times when energy is expensive and in high

demand, reducing the need to power up fossil-fueled peaker plants

to meet this demand. Homeowners are compensated for providing

power to the grid, while grid operators don’t need to run expensive,

large scale infrastructure. This lowers costs for all electricity users

and everyone financially benefits from this program, which also

reduces the need for dirty, expensive fossil fuel plants to deliver

energy.

After piloting this program with Sunrun and others, National Grid and

the other utilities in Massachusetts made these programs available

statewide. This means that home solar batteries will reduce costs

and pollution for the entire Commonwealth and shows the pioneering

partnerships that Sunrun is forging.

Solar for All: Illinois Solar for All is a state program launched in 2019 that creates pathways for low-income communities to engage

in the clean energy economy. With Illinois Solar for All, participants

can get home solar for $0 down, and monthly costs and fees will

not be higher than 50% of the value of the energy generated from

that system. There is also a job training component, with training

programs and job fairs to ensure that disadvantaged populations

also reap the benefits of clean energy job creation. In the works

since 2014, Sunrun has been integral to the development and

implementation of this program. Several Sunrun project managers

working with the Solar For All program are helping families from

their own communities gain access to solar energy where it has been

traditionally underrepresented.

30

2019 IMPACT REPORT | SOCIETAL IMPACT

In 2019, Sunrun partnered with key industry allies to help expand solar energy in underrepresented communities

across the country. Everyone has a right to solar energy, and Sunrun is committed to enabling more solar access

in the communities that need it the most.

GRID ALTERNATIVES

In 2019, Sunrun continued its partnership with GRID Alternatives (GRID).

GRID is a national leader in making solar power and jobs accessible to

underserved communities. The partnership between Sunrun and GRID,

now in its ninth year, supports job training and solar installations for low

income families and traditionally underserved communities.

In 2019, Sunrun and GRID installed 4.5 megawatts of solar for 917 low-income families, providing $19 million in

lifetime savings. The solar projects also prevented 45,000 tons of GHG emissions in communities that bear the

brunt of environmental pollution and health disparities. Finally, the 49,000 hours of job training delivered by Sunrun

and GRID provide opportunities for people to acquire new skills and prepare for careers in the solar energy industry.

BLACKS IN GREEN

In 2019, Sunrun announced its partnership with Blacks in Green (BIG), an

environmental economic development organization designed to tackle

pollution and poverty, and expand access to solar energy and jobs in the

Chicagoland area.

The goals of the partnership are to increase access to clean, affordable

home solar energy for South Side Chicago homeowners, and to increase

clean energy career opportunities for residents in traditionally underserved

and underrepresented communities.

The partnership includes a commitment from Sunrun to recruit solar trainees from the BIG network. Sunrun will also

support BIG at educational events throughout the community so residents can learn about rooftop solar, including

the Illinois Solar for All program, designed by community members and policymakers to increase access to solar

energy for underserved communities.

GHG Accounting Data Sources and Methodology GHG Emissions

Reported scope 1 emissions include vehicle fleet emissions, which are based on data from Sunrun’s fleet- management group, and emissions from on-site natural-gas consumption, which are based on average office

and warehouse square footage figures outlined in the U.S. Energy Information Administration’s (U.S. EIA) 2012

Commercial Building Energy Consumption Survey (CBECS). An emissions factor in metric tons of CO 2 e per

megawatt deployed was calculated for Sunrun’s operations across various eGRID regions and applied to partner

megawatts deployed across various eGRID regions to estimate partners’ emissions attributable to their vehicle

fleets and their natural-gas consumption in offices and warehouses.

Reported scope 2 emissions include those from purchased electricity, which are calculated for both Sunrun and our partners in an analogous fashion to scope 1, using figures for office and warehouse square footage as outlined

in the U.S. EIA’s 2012 CBECS. An emissions factor in metric tons of CO 2 e per megawatt deployed was calculated for

Sunrun’s operations across various eGRID regions and applied to partner megawatts deployed across various eGRID

regions to estimate partner emissions attributable to electricity consumed in offices and warehouses.

Reported scope 3 emissions are based on a study by one of Sunrun’s major module suppliers, which outlines emissions figures for a module that aligns well with the average module wattage deployed by Sunrun over the

reporting period. An additional 20% factor was added to this calculation to account for emissions attributable to

balance-of-system (BOS) components, drawing from information in a 2011 report from the International Energy

Carbon balance calculations are based on derated expected production over 30 years and actual kilowatt-hour

production to date. All kilowatt-hour values are translated into metric tons of CO 2 e emissions avoided using the GHG

equivalencies calculator provided by the United States Environmental Protection Agency.

The carbon payback period is derived by taking Sunrun’s carbon footprint, adding an additional 5% to account

for product end use, and dividing that figure by watts deployed. This gives us the carbon footprint of the average

system, which, when divided by the expected carbon offset of the average system after one year, results in the

carbon payback period.

Calculations for the comparison to fossil fuel are based on average Sunrun system size deployed, expected average

system production derated at 0.06% per year over 30 years, and Surnun’s carbon footprint. Fossil-fuel figures for

other sources of energy were taken from a 2013 study by the National Renewable Energy Laboratory (NREL), Life

Cycle Greenhouse Gas Emissions from Electricity Generation.

Calculations for prevented air pollution and water consumption are derived from expected average system

production derated at 0.06% per year over 30 years for systems deployed in 2016 through 2019. Energy production

was equated to prevented air pollutants and water consumption using information provided by the U.S. Geological

Survey4 and eGRID’s Year 2010 Summary Tables.
