Photovoltaic panel power generation area classification table

Which data format is used in a PV power station map?

The data format is GeoTIFF while the spatial reference is WGS-84. Meanwhile, only two kinds of values are in the PV power station map, where 0 stands for the non-PV regions while 1 represents the PV power stations.

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.

How do we classify PV power plants from composite images?

We applied a pixel-based random forest (RF) model to classify the PV power plants from composite images in 2020 with a 30 m spatial resolution on the Google Earth Engine (GEE). The resulting classification map was further improved by a visual interpretation approach.

How are PV arrays arranged in the construction of PV power stations?

In the construction of PV power stations, the distribution of PV arrays is usually concentrated in areas with gentle terrain, while their arrangement in areas with undulating terrain takes more consideration of the influence of topographic factors, resulting in a large variance in spacing between PV arrays.

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 technical potential of a photovoltaic system?

As for the technical potential, the PV module’s conversion efficiency and the performance ratio (PR) are widely used to evaluate the PV system. The progress in photovoltaics updated the highest confirmed efficiency of the crystalline silicon cells, which can now reach 26.7% under the global 1000 W/m 2 at 25 °C.
