What Are The Factors That Affect The Power Generation Of Photovoltaic Modules?

1. Environmental factors
The lighting conditions (solar energy resources) vary in different regions, and areas with superior solar energy resources naturally have higher power generation.

Overall, China is a region with abundant solar energy resources, but there are still significant differences in solar energy resources among different regions.

Northwest regions, such as Xizang, Qinghai and Gansu, are the regions with the most abundant solar energy resources in China and belong to the first category; Shandong, Henan, southeastern Hebei, southern Shanxi, northern Xinjiang, Jilin, Liaoning, Yunnan, northern Shaanxi, southeastern Gansu, southern Guangdong, southern Fujian, central northern Jiangsu, and northern Anhui are the second category regions with abundant solar energy resources; The middle and lower reaches of the Yangtze River, Fujian, Zhejiang, and a part of Guangdong are classified as three areas with average solar energy resources; Sichuan and Guizhou provinces are the four regions with the least solar energy resources.

2. Installation angle of photovoltaic module array
When installing components, they should be installed in the direction with the most abundant sunlight (the best direction is due to the south), and the installation angle is generally determined by the latitude of the installation location, with slight differences in different regions.

3. Quality of photovoltaic systems
The solar energy conversion rate of high-quality photovoltaic products is significantly higher than that of low-quality products. It is important to choose qualified photovoltaic products from reputable manufacturers, which is a prerequisite for ensuring high power generation of photovoltaic power stations.
