At present, solar street lamps have been popularized in our life. Solar street lamps can be seen everywhere, such as parks, roads, factories, communities, scenic spots, etc. many rural areas have also installed solar street lamps. I won’t say more about its many advantages.
Solar street lamp is a fully automatic and integrated working mode, which does not need manual control. The power source depends on solar panels. During the day, solar panels absorb the solar radiation on the surface, convert the light energy into electric energy and store it in the battery, which has high requirements for temperature and weather. Therefore, the work efficiency will be reduced at low temperature. There are three main methods to improve the power generation of the battery board at low temperature.
1. keep the surface of the battery board clean
If the surface of the solar panel is covered with snow, the snow should be cleared in time, because when the snow blocks the solar panel, the solar panel can not smoothly absorb solar radiation. Without the support of light energy, the solar panel can not work. After the snow falls, the power generation capacity of solar panels can be guaranteed at low temperature.
2. large angle installation
Large angle installation of solar panels can effectively avoid the rapid accumulation of snow, reduce the speed and thickness of snow accumulation, and avoid frequent manual cleaning. Of course, the so-called large angle installation is only a moderate increase in the installation angle of the solar panel without affecting the solar panel receiving sunlight.
3. pay attention to the installation distance
When installing solar panels, try to keep the panels away from houses with eaves or sheltered buildings, so as to avoid the snow on the top of surrounding buildings falling onto the panels and slowly accumulating from the bottom of the panels, so as to cover most of the panel surfaces and affect the light energy reception of the panels.
