In winter, solar mounting brackets can accumulate snow easily. And the loss of power cause by snow accumulation exceeds 5%. Cleaning the photovoltaic modules in time can avoid the hot spot effect and prolong the service life of the modules.

In many cases, the reflection of snow will slightly promote photovoltaic power generation. If the snow does not cover the panel module, the snow on the ground will emit sunlight back like a mirror, and the power generation will increase. However, if the snow completely covers the modules, only a small part of the sunlight passes through the snow and hits the photovoltaic modules, which will affect the photovoltaic power generation.

How to install the solar panel mounting structures to reduce snow accumulation on the solar panel?

1. To install the solar racking system with a large angle. For areas that often snow, the inclination angle of the solar racking system can be larger, so that the snow will fall and reducing the accumulation speed of snow. This can reduce the speed of snow accumulation and eliminate the trouble of cleaning snow from time to time.

2. To keep a small distance from the ground to the panel during installation. Snow will not accumulate on the bottom of the panel and cover the entire panels.

3. Small photovoltaic power plants can also be covered with cloth or plastic bags when it snows, and they can be uncovered when the snow stops.

4. If it is a tiled roof, you need to pay attention to the load. When the load reaches the critical value, it is very easy to cause collapse. If it is a tile roof solar mounting system, and it’s installed flatly along the slope of the roof and use clamp to install, the load is about 0.15KN/㎡.
