The installation of 1.85 MWp solar rooftop PV power generation system at the commercial building in this study is technical and economic approved. Using solar energy is sustained for energy efficiency. In the first year, the project achieved energy production of 2,678 MWh resulting in energy cost saving of 269,317 USD.
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 shown, the installed capacity of the grid-connected solar rooftop PV power generation system is 1.85 MWp; however, the maximum power consumption required for the commercial building in 2020 is 4.9 MWp. To gain sufficient power, therefore, the installation of additional solar PV power generation system will be done. Fig. 3.
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.
It is notably observed that the installation of solar PV power system on the rooftop of commercial and residential buildings has continuously increased in terms of the energy efficiency improvement and building space utilization in electricity generation.
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.
