Micro knowledge of solar panels install
The solar panels install and use of solar off-grid systems have become very common, including solar power supply systems and wind-solar hybrid power supply systems. It is not only green and environmentally friendly, but also solves the problem of electricity consumption in remote areas without electricity. The solar off-grid power supply system converts solar energy into electrical energy and stores the electrical energy inside the battery through the controller, and the electrical energy stored in the battery is converted into electricity through the controller; , rectified by the controller and stored in the battery. Solar panels install needs to pay attention to many details, and wrong solar panels install has a great impact on the power generation of the system.
Generally speaking, the square array of solar panels faces due south, and the square array can be understood as the surface of the solar panel. When the angle between the vertical plane of the solar panel array and the south direction is 0 degrees, the solar panel generates the largest amount of electricity, and the peak time of solar radiation energy is later at noon, about 12:00 to 1:00 noon. It means that from 12:00 to 1:00 noon, when the sun shines on the solar surface at a vertical angle of 90 degrees, it is the peak time of power generation. At this optimal azimuth angle, if you deviate the solar panel to the east or the west by 30 degrees from due south, the power generation of the solar panel will be reduced by 10%~20% accordingly, so the azimuth angle of the solar panel is very important. The azimuth angle, the power generation of the solar panel will be reduced.
Application site selection
1. Azimuth and tilt angle
In different seasons, the orientation of the solar cell array will be adjusted accordingly to obtain correspondingly larger power generation. In different seasons, the peaks of insolation in various directions will also be different. Generally, when the array is facing due south, the solar cell power generation is the largest. Like the azimuth angle, the constraints on the inclination angle of the roof, the inclination angle of snow falling and drainage, etc. of photovoltaic solar energy should also be considered in the design and solar panels install. It is related to geographic latitude. When the latitude is higher, the corresponding inclination angle is also larger.
2. Avoid blocking
If the solar photovoltaic panel cannot be directly illuminated by sunlight, and only scattered light or local area is used for power generation, the power generation at this time is about 10% to 20% less than that of unshaded solar energy. Therefore, it is necessary to avoid blocking between the panels, including surrounding buildings such as utility poles, trees, and corners of house eaves.
