... PV) are installed on rooftops due to the area availability of rooftops, solar irradiation hits the rooftops or the increase in building demands . Several papers were investigated PV behavior on rooftops [22, .
The building rooftop presents a wealth of spatial opportunities for promoting the utilization and conservation of solar energy. The installation of photovoltaic panels on rooftops is a feasible and convenient method for integrating renewable energy sources into buildings.
Despite numerous benefits, there are potential negative impacts from rooftop PV implementation. Currently installed photovoltaic panels typically convert only 15–18% of the incoming solar radiation into electricity [ 7 ]. As a result, most of the incident radiation is absorbed into the panel as heat and released into the urban environment.
This paper presents a review of the impact of rooftop photovoltaic (PV) panels on the distribution grid. This includes how rooftop PVs affect voltage quality, power losses, and the operation of other voltage-regulating devices in the system.
It can be harnessed using photovoltaic panels on top of buildings to reduce dependence on the electrical grid and to achieve the status of net-zero energy building. However, the rooftop coverage by solar panels can modify the heat interface between the roof surface and its surrounding environment.
There is also not a clear consensus on the impact of rooftop PV panels on building heating and cooling loads. The majority of studies suggest that rooftop PV arrays provide beneficial shading to the building and reduce cooling loads [ 15 – 19 ].
