1. Develop non-arable land resources
Mountains are mostly unused barren mountains, slopes or low-yield forests. Photovoltaic development does not need to occupy high-quality farmland or urban land, which is in line with the national land intensive policy. For example, the Chuxiong mountain photovoltaic project in Yunnan uses barren slopes above 2,000 meters above sea level, with an installed capacity of 500MW and an annual power generation of more than 700 million kWh.

2. Three-dimensional space reuse Through the "photovoltaic + agriculture/forestry" model, shade-tolerant crops (such as Chinese medicinal materials, fungi) are planted under the photovoltaic panels or animal husbandry is developed to achieve "one land, two uses". For example, the mountain photovoltaic project in Datong, Shanxi, which is located in the coal mining subsidence area, simultaneously plants astragalus, increasing income by more than 3,000 yuan per mu. Natural advantages to improve power generation efficiency

3. High altitude and low temperature environment efficiency
Mountains are usually at a high altitude, with thin air and strong ultraviolet radiation. The amount of solar radiation received by photovoltaic modules is 5%~10% higher than that of plains. At the same time, the low temperature environment can reduce the operating temperature of the module (the efficiency increases by 0.4%~0.5% for every 1℃ reduction) and extend the service life.
