After hearing the word solar street lights, many people will think that since the use of solar energy, the temperature in the south should be good in the south. The sun's irradiation and temperature are not directly related.

The so -called sunshine peak refers to the average power generation that can be provided by the sun in a square unit (the theoretical conversion rate of solar panels is 100%). The actual results show that the Southern Rizhao peak represented by Guangzhou is 4.0-4.5, while the sunshine peak value of the Northern Inner Mongolia region in China is 5.5-5.7. So, what is the reason for this difference? In fact, in the southern areas, there are more clouds covered by the sky, the humidity of the air is large, the dust content is large, the conditions of the air filter a lot of sunshine energy, and the light can be accepted by landmarks. In the Inner Mongolia area, the sky is high, the air is dry, the sun is shining, and the sunlight that reaches the ground contains high energy. Similar to the Inner Mongolia area, there are drought and high -altitude areas such as Xinjiang, Tibet in China, Tibet. Therefore, when we do the configuration of the solar street lighting system, we cannot blindly look at the installation in the south or the north. We must check the sunshine coefficient and input the sunshine coefficient into the corresponding calculation formula. The entire system configuration is performed according to experience.
