This paper has exclusively examined the power generation potential of distributed photovoltaic (PV) systems installed on rooftops. However, in practical applications, distributed PV systems are also prevalent in various other scenarios, such as alongside roadsides, over water surfaces, and within public facilities.
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.
In recent years, the advantages of distributed solar PV (DSPV) systems over large-scale PV plants (LSPV) has attracted attention, including the unconstrained location and potential for nearby power utilization, which lower transmission cost and power losses .
In the divided suitable area method, rooftop distributed photovoltaics are developed in the order of high, medium and low suitability, with the installation tasks for each category completed every two years. The balanced development method involves simultaneous photovoltaic installation in all cities over six years, completing one-sixth each year.
This paper opts to investigate roof-mounted distributed photovoltaics, which are more suitable for development in densely populated areas. Current research on distributed photovoltaics largely focuses on vague estimations of power generation potential, without adequately considering the specific development conditions of different regions.
