Typical load of rooftop solar power plant is about 15-20 kg/sq.m., which seems manageable for the existing building structures. However, this detail will need to be confirmed by structural consultant during actual implementation. Average Capacity Utilization Factor (CUF) of the power plants is ~ 16%.
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.
Both new and existing roof frames should have enough capacity to safely accommodate the additional load imposed from the installation of the solar system. The additional PV system weight can be incorporated in the design during early stage of the project life. The process is more complicated for existing building.
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.
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."
