As the name suggests, a solar rooftop system is where the solar panels are installed on the roof of any Residential, Commercial, Institutional or Industrial building.
This can be of two types:
Some Solar rooftop systems that have a battery as storage facility. Such solar systems can ‘’store’’ electricity in the battery and hence are named so.
n grid connected rooftop or small Solar Photo Voltaic (SPV) system, the DC power generated from SPV panel is converted to AC power using power conditioning unit (eg. Inverter) and is fed to the grid either of 440/220 Volt three/single phase line or 33 kV/11kV three phase lines depending on the capacity of the system installed at Residential, Commercial, Institutional or Industrial building and the regulatory framework specified by respective authorities. These systems generate power during the day time which is utilized fully by powering captive loads and feed excess power to the grid as long as grid is available. In case, where solar power is not sufficient due to cloud cover etc., the captive loads are served by drawing power from the grid.
As per the policy, such rooftop systems can be installed at rooftops or/and Open areas on the land, building or infrastructure or part or combination thereof.
