To prolong the service life of solar street lights, it is the key to prevent the panels from dust

According to reports, many solar street lights and other power generation equipment are in urgent need of cleaning, because dust, sand, etc. have fallen on the battery panels for a long time, which seriously affects the power generation efficiency. Experts estimate that the resulting loss of power generation can reach 9%. And so far, there is no really good cleaning solution on the market. There is a risk of slipping when working on sloping equipment. Moreover, people's weight is not light, and the panels are often unable to support them, etc. After the solar street light panels are covered with dust, the energy conversion of electricity will gradually decline. From 5-7 days after each charge at the time of installation, it is reduced to only 4-6 days, 3-5 days, 2-3 days and 1-2 days. In the end, the battery cannot be charged. At the same time, the power will gradually decrease, such as the original 100W may drop to 80W, 70W is different. It is understood that in some areas with severe dust, the battery has not been charged for a long time due to the thick dust accumulation of the solar panel. Therefore, it simply cannot function as it should. This is a huge loss to users. It will also make some new users doubt and lose confidence in the use of solar energy. At present, the solution to the dust problem of solar street light panels is to increase the capacity of the panels. In this way, the cost will increase, the user will pay more, and the problem cannot be solved fundamentally.
