Installation of photovoltaic solar power generation in rural areas

How can solar PV be used in rural areas?

The rural annual electricity demand can be satisfied by installing PV modules on all rooftops or facades. Rooftops facing south and north and facades facing south and west have the highest PV potential ranks. They account for more than 80% of the rooftop solar PV potential and over 90% of the facade solar PV potential respectively.

Can stand-alone solar photovoltaic systems be used in rural areas?

The electrification of rural areas has benefited greatly from stand-alone solar photovoltaic systems. It is necessary to consider the energy demand for the proposed usage when designing off-grid stand-alone solar-power systems.

Are roof-mounted solar PV systems a viable energy source for rural microgrids?

In rural areas, roof-mounted solar PV systems are among the main energy system development targets, and the spatial distribution information of PV power generation is crucial for the construction of rural microgrids.

Can rooftop solar energy be used in rural areas?

There are nearly no studies on rooftop solar energy potential in rural areas. Although PV is very prosperous in rural areas, it can meet the energy demands of local farmers and supply extra electricity to urban areas. This can promote clean energy in rural areas and improve the living conditions of farmers.

Can GIS data accurately estimate solar PV potential in rural areas?

In this study, we proposed a novel approach that for the first time constructed rural 3D building models from publicly available GIS data and accurately estimated the rooftop-and-façade solar PV potential in rural areas. We used Google Earth satellite images to create a rural building dataset, which was then used to train an RF model.

How much solar power can be used in rural areas?

The calculation results show that there are still more than 6.4 billion m 2 of building roof area in rural areas that can be used for the investment and installation of distributed PV systems, and if used rationally, the power generation will be able to reach 1.55 times the total power consumption in rural areas.
