What is the maintenance method of solar street light in winter?
1. Increase the battery capacity and photovoltaic panel power.
Solar lights have low illumination in winter, and solar panels do not generate enough power. At the same time, the discharge depth of the battery can only reach about 70% of the summer. Various conditions weaken the power storage capacity of solar lights, but also to cope with the improvement of solar lights. High with low wattage light source, all winter!
2. Adjust the angle of the photoelectric panel and the depth of the battery.
Winter is coming, snowy weather is essential, in heavy snow, solar panels across the country is just a snowy situation, if not dealt with in a timely manner, the sun lamp will be bright in the daytime until the power disappears, affecting the use of solar energy. The editor of the solar light operating system introduced an article.
If the battery is buried too shallow, the cold climate in winter, the battery will frostbite when it freezes, resulting in insufficient discharge. Usually in cold areas, the battery should be buried at least 1 meter deep with 20 cm of sand at the bottom, which is conducive to emitting moisture, thus extending the service life of the battery.
3. Regular arrangement and protection.
Solar panels have not been cleaned for a long time. Too much dust will affect power generation. In some places, the lack of power generation is due to frequent accumulation of snow and snow re-covering solar panels. Therefore, it is best to clean the solar panels of dust and snow once every two months.
