Solar power is known as a clean and never-ending source of energy. In that field, rooftop solar power has been given attention by many developing countries in order to make the most of the "idle" roof area to bring efficiency. I. Learn about rooftop solar power - a better solution for saving energy A rooftop solar power is a system of solar panels installed on the roof of a building, commercial, industrial or residential. These solar PV systems are typically much smaller in capacity than terrestrial solar power plants. Rooftop systems on residential buildings typically range in capacity from 5-20KW, while systems on commercial buildings typically reach 100KW or larger. About the working mechanism, the DC current (Direct Current) generated by sunlight shining on the tons of batteries runs into the inverter to turn into AC (Alternating Current)  and then runs into the two-way meter to be recorded and stored for payment, then run into the electricity-using equipment of the ho...
