As energy storage systems are typically not installed with residential solar photovoltaic (PV) systems, any "excess" solar energy exceeding the house load remains unharvested or is exported to the grid. This paper introduces an approach towards a system design for improved PV self-consumption and self-sufficiency.
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.
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.

Their incorporation into building roofs remains hampered by the inherent optical and thermal properties of commercial solar cells, as well as by esthetic, economic, and social constraints. This study reviews research publications on rooftop photovoltaic systems from building to city scale.
Solar or photovoltaic (PV) installations have been gaining popularity in the last few decades as a renewable energy source to power commercial and industrial buildings, but also offices and homes. Most commercial buildings have flat roofs, providing ideal support and easier access for PV installations than pitched roofs.
In just one hour, more solar energy hits the Earth than the world uses in a year—and solar roofs are here to harness it. These sleek, high-tech panels are revolutionizing how we think about energy, generating clean electricity that can cut your carbon footprint by up to 80% and save thousands on energy bills.
