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.
How accurate is the spatial distribution of rooftop PV power generation potential?
By combining the above results and setting the solar radiation parameters and PV system efficiency, we can obtain the spatial distribution of the rooftop PV power generation potential in rural areas. This method is applied in northern China on a village and a town scale, and the overall accuracy of the revised U-Net model can reach over 92%.
What is the maximum rooftop solar PV power generation in village a?
When we only considered the PI method, the maximum rooftop solar PV power generation of a single building in Village A was over 40,000 kWh, with an average of 16,900 kWh. Fig. 19. Rural rooftop solar photovoltaic (PV) potential distribution of each roof in Village A; OTI: optimal tilt installation, PI: parallel installation.
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.
What are roof-mounted solar PV systems?
Roof-mounted solar PV systems have been gaining increasing attention as they can meet a building’s distributed energy demand and save transmission and conversion costs through local usage. They also save land use and scarcely require maintenance, whether installed as part of a building or as a retrofit facility , .
Are empirical utilization coefficients suitable for rooftop solar PV generation potential analysis?
Whether obtained by estimation or sampling surveys, the empirical utilization coefficients could only offer the quantity instead of distribution information, so it is not suitable for rooftop solar PV generation potential analysis in rural areas. Moreover, few studies have been published in recent years owing to the large estimation errors.
