Solar rooftop are solar panels placed on top of roofs of commercial, institutional or residential buildings. They capture the light energy emitted by the sun and convert it into electrical energy. This setup is also known as solar rooftop photo-voltaic system.
Even though the quantity of solar radiation is relatively small, it still generates more total power. When we only considered the PI method, the maximum rooftop solar PV power generation of a single building in Village A was over 40,000 kWh, with an average of 16,900 kWh. Fig. 19.
Here you will learn how to calculate the annual energy output of a photovoltaic solar installation. r is the yield of the solar panel given by the ratio : electrical power (in kWp) of one solar panel divided by the area of one panel. Example : the solar panel yield of a PV module of 250 Wp with an area of 1.6 m2 is 15.6%.
