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.
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.
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."
Using this hybrid framework, we calculated the available rooftop area in Shanghai, excluding the Chongming Island, and produced a detailed map of PV potential. Results show that the estimated annual potential for rooftop solar radiation in Shanghai stands at 257,204 GWh, with a predicted annual PV electricity generation of 49,753 GWh.
The first detailed global assessment of the electricity generation potential of rooftop solar panels has revealed that the total global potential for electricity produced in this way exceeds all the energy used worldwide in 2018.
For technical potential calculations, we assumed that 100% of the estimated rooftop is available for installing solar panels i.e., orientation and slope of the building are not accounted for the 100% rooftop availability assumption-based results in our main analysis.
