How to read the attached Shade report :
1. Roof Irriadiation : Roof irradiance refers to the amount of sunlight energy that hits a rooftop.If a roof receives high irradiance, it means it gets strong and consistent sunlight, which is ideal for solar power.
In the attached reference picture , the lighter the roof colour , the better irradiance it has and the darker the roof , the lesser irradiance it has.
2. Summary: This part summarizes the various components as explained below:
a) Array Panel count - Total count of panels in each array.
b) Azimuth - The Azimuth of each Array.
c) Total Tilt - The per Array tilt
d) Annual TOF (Tilt and Orientation Factor) percentage - It is a critical metric used to optimize the placement of solar panel arrays to maximize their energy output. Achieving the highest energy generation from panels occurs when they are positioned at their optimum tilt and azimuth angles.
e) Shading Loss - This confirms annual shading loss percentage considering the array tilt , azimuth , panel tilt.
f) Annual Solar Access - The Solar Access percentage on each Array
g) TSRF - TSRF (Total Solar Resource Fraction) -TSRF is a key performance indicator used to assess how much of the available solar resource (sunlight) at a given location is actually available to a solar panel, after accounting for shading and tilt/orientation losses.
Calculation of TSRF- The Total Solar Radiation Factor (TSRF) is calculated by multiplying the TOF by the Solar Access of the panel array. This calculation incorporates shading factors into the determination of solar energy, providing a more accurate estimation of energy generation potential.
