A rooftop solar power system, or rooftop PV system, is a photovoltaic (PV) system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure.[1] The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters and other electrical accessories.[2]

Rooftop mounted systems are small compared to utility-scale solar ground-mounted photovoltaic power stations with capacities in the megawatt range, hence being a form of distributed generation. 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.
As of 2022, around 25 million households rely on rooftop solar power worldwide.[3] Australia has by far the most rooftop solar capacity per capita.[4]
