Structural analysis
There are regularly a wide range of criteria that should be considered in settling on a
decision. It is key to distinguish the criteria, and to settle on the decision as for those criteria as
accurately as could reasonably be expected (Olabanji et al, 2014). The matter is further disturbed
when there are numerous options from which to pick; in these cases, not just does every option
need to be inspected, but every one of the choices must be dealt with reliably to guarantee that a
last correlation of the considerable number of choices is reasonable. A weighted decision matrix
is a straightforward apparatus that can be exceptionally valuable in settling on complex
decisions, particularly in situations where there are numerous options and numerous criteria of
differing significance to be considered. Weighted decision matrices are regularly utilized as a
part of outline designing as a subjective apparatus to assess choices. A weighted decision matrix
is an instrument used to contrast choices with deference with various criteria of various levels of
significance (Mazak et al, 2014). It can be utilized to rank every one of the options in respect to a
"fixed" reference and along these lines make a halfway request fo the options.
The Panel Dimensions are 65.94 × 39.41 × 1.3 inches and weighs 39.5 pounds. The
proficiency on the Sunmodule Plus SW 285-watt solar panel is up to 16.7% and its energy
resilience is 0/+2%. This specific model has a matte silver edge and is made of mono-crystalline
2
silicon cells, which numerous consider to be more alluring. The SW 285-watt Sunmodule Plus is
intended for long haul use, sturdiness and convenience. It will support heaps of up to 113 pounds
for each square foot, which implies it will withstand even the harshest climate conditions. Its
Version 4.0 edge is good with "Top-Down" and "Base" mounting techniques. Each panel has 60
cells per module producing 285 watts.
The exclusive surface coatings and granular composition of the Sunmodule's front glass
make two impacts: the diminishment of the light reflected all things considered (air-glass
interface) and the inner catching of the light reflected from the solar cells in the module. These
two impacts join to make a to a great degree productive and elite PV module. The licensed box is
channel outline plan gives uncommon firmness in twisting and torsion. The cover with 4mm
glass is set somewhere down in the casing channel and secured with accuracy connected glue.
The edge is gathered by press fit to amplify quality and life span. The outcome is a to a great
degree vigorous bundle that can be mounted in any introduction and can withstand static heaps
of up to 113 psf (Solar World, 2016). Plus-Sorting ensures most noteworthy framework productivity. Solar World just conveys modules that have more prominent than or equivalent to
the nameplate evaluated power. The positive force resistance ensures most extreme framework
effectiveness. Just modules accomplishing or surpassing the assigned ostensible force in
execution tests are dispatched. The force resistance ranges between - 0 Wp and +5 Wp. Potential
induced degradation is a marvel where the force yield of a solar module is diminished when
3
presented to high negative voltage predisposition between the cells and ground. Potential
induced degradation can conceivably influence the execution of individual modules and also the
general force yield and proficiency of a whole solar force creating framework. Solar World Sun
modules have been ensured as Potential induced degradation free by validated research centers.
The formula to estimate the electricity generated in output of a photovoltaic system is :
E = A * r * H * PR
E = Energy (kWh)
A = Total solar panel Area (m²)
r = solar panel yield (%)
H = Annual average solar radiation on tilted panels (shadings not included)
PR = Performance ratio, coefficient for losses (range between 0.5 and 0.9, default value = 0.75)

The final solar panel system design will be located at the Grey Mountain site and will incl
ude SolarWorld SW 285 MONO panels and Solectria SGI750XTM inverters with a fixed tilt.
Further analysis of the components for the system will give us a design that we can conclude in t
he overall design of the project.
In order to take this design further research willbe done on the chosen location and the system de
sign. From the site assessment decision matrix, the Grey Mountain site scored the most points. Si
nce the sites are all near each other and the climates are all very similar, the solar resource score f
or each site is the same. The Twin Arrows site and Angell site are less than 30 miles from Flagsta
ff so their score for the distance from Flagstaff is more than that of the Grey Mountain site. All o
f the sites are located within 5 miles of a substation but the Grey Mountain site is close to a large
r substation. The landscape for all of the sites is very similar, which is why the score is the same.
Solar World solar panels are accessible with silver or dark segments. These modules meet
their stringent Solar World quality measures and meet and surpass all industry principles and
affirmations. They likewise convey our 25-year straight guarantee to ensure most extreme
execution through the lifetime of your framework. Solar World does numerous a bigger number
of tests than required by global guidelines. Truth be told, each part they utilize must meet no less
than 3 times IEC necessities. These tests offer us some assistance with providing so as to
improve the nature of their items important data on the conduct of their solar modules. Solar
World Sun modules are in a perfect world suited for long haul use in farming, as affirmed by the
German Agricultural Society and TÜV Rhineland. For instance, lab tests have confirmed that our
5
panels can effectively withstand the impacts of smelling salts intrinsic in horticultural conditions
amid a 20-year period.
