[PDF Version]However, compared with the enormous potential of solar power, the level of its utilization is low at present. Thus, further development of PV power has significant impetus for the in-depth development of energy conservation and emission reduction and the optimization of energy structure adjustment in China.
Eventually, we established a map of PV power plants in China by 2020, covering a total area of 2917 km2. We found that most PV power plants were situated on cropland, followed by barren land and grassland, based on the derived national PV map. In addition, the installation of PV power plants has generally decreased the vegetation cover.
This research presents a comprehensive study based on field survey and remote sensing investigations of 40 PV plants in the Badain Jaran Desert and Tengger Desert, two of the hot solar energy exploration areas in China.
In recent years, with more policy support from the Chinese government, the photovoltaic (PV) industry has been experiencing a larger-scale development to replace traditional energy. With the stimulation of relevant national policies, the PV industry in China represents an opportunity for high growth.
Thus, the following four output variables contribute to the environmental effects of PV plants in China. Installed Capacity: The total installed capacity of a PV power system refers to the sum of rated effective power of the PV generator sets actually installed in the system. The most common installed capacity unit in China is MW.
The total area of the PV power plants in China is about 897 km2, based on Dunnett's dataset. We manually modified this dataset with Google Earth's background to ensure that the PV samples are located inside the PV power plants.

Where temperatures below about 95 °C (200 °F) are sufficient, as for space heating, flat-plate collectors of the nonconcentrating type are generally used. Because of the relatively high heat losses through the glazing, flat plate collectors will not reach temperatures much above 200 °C (400 °F) even when the heat transfer fluid is stagnant. Such temperatures are too low for to electricity.
