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.
As of May 2017, installation of a rooftop solar system costs an average of $20,000. In the past, it had been more expensive. Utility Dive wrote, "For most people, adding a solar system on top of other bills and priorities is a luxury" and "rooftop solar companies by and large cater to the wealthier portions of the American population."
The rooftops installation capacity potential for photovoltaic systems and annual energy output were estimated as 5.97 GW and 5981 GWh respectively with an error rate of 10–15%. Encompassing 14.2% of the total used electricity of Hong Kong. Additionally, approximately 3,732,000 t/y of greenhouse gas emissions reduction was estimated .
Gernaat et al. (2020) estimated that the global suitable roof area for PV generation was 36 billion square meters. This represents a potential of 8.3 PWh/y, which is equivalent to 150% of the global residential electricity demand in 2015. This demonstrates the potential of replacing traditional electricity sources with rooftop PVs.
Shrestha and Raut (2020) assessed the technical, financial, and market potential of the rooftop PV system on residential buildings in three major cities of Nepal through a field survey instead of simulation, and the results showed that 35% of the city's annual electricity consumption could be covered by solar power.
