    en.wikipedia.org/wiki/Rooftop_solar_power

    Most rooftop PV stations are Grid-connected photovoltaic power systems. Rooftop PV systems on residential buildings typically feature a capacity of about 5–20 kilowatts (kW), while those mounted on commercial buildings often reach 100 kilowatts to 1 megawatt (MW). Very large roofs can house industrial scale PV systems in the range of 1–10 MW.
