How to Calculate Solar Potential for Rooftop Panels
4 · Example: If your usable roof area is 80 square meters, the solar irradiance is 5 kWh/m²/day, and you plan to install 20% efficient solar panels, the system size would be calculated as follows: System Size = Usable Roof Area x Solar Irradiance x Panel Efficiency. System Size = 80 m² x 5 kWh/m²/day x 0.20. System Size = 80 kWh/day
How to Calculate the Surface Area Required by Solar Panels
Suppose the area is A square meters then the equation becomes. 1000 x 0.20 x A = 25000. 200 x A = 25000. A = 25000 / 200. A = 125 square meters. This is for panels lying flat on the ground. We would suggest that an area of at least 200 square meters must be reserved due to the following three reasons.
