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.
Urban building rooftops provide promising locations for solar photovoltaic installations and can contribute effectively to make nearly net-zero energy buildings . Rooftop solar photovoltaics can be considered an effective solution for urban energy management to solve urban energy requirements and environmental problems .
However, the effectiveness of rooftop photovoltaics (RTPV) implementation varies globally. A collaborative study between the JRC and research institutions worldwide shows that RTPVs have a great potential to achieve net-zero energy buildings across various climatic zones and roof thermal insulation levels.
A merging national datasets methodology was developed to estimate rooftop solar potential, rooftop photovoltaic systems distribution, and socioeconomic and demographic characteristics for four US cities namely Riverside-California, San Bernardino-California, Washington-DC, and Chicago-Illinois.
