How to Maintain Solar Panel of Solar Energy Street Light?
Some people installed solar energy street lights thinking that they could be used forever. However, they found that as the use time increases, the lighting effect becomes worse, and the intensity of the lamp becomes lower and lower. In the use of solar energy street lights, in order to ensure long-term and effective lighting efficiency, the function of solar panels must be guaranteed. If there is a failure, the use of the entire system of solar energy street lights will be affected.
Why do solar panels fail to work?
During the use of solar energy street lights, some dust, leaves and other debris will inevitably fall on the solar panels or be covered by snow in winter, causing partial shadows on the solar panels. These partial shadows will cause the current and voltage of some monolithic cells change, leading to local heating, and some obvious burnout hot spots will appear after a long time. At the same time, the photoelectric conversion rate decreases, the charging is insufficient, and the battery power is insufficient. When the solar panel has a hot spot effect, after reaching a certain level, it will melt the solder joints of the panel components, destroy the grid lines, and slowly damage the entire panel of the panel components. This will not only seriously affect the lighting system, but also at least reduced to 10% of its lifespan. Therefore, after installing solar energy street lights, we should regularly organize maintenance personnel to conduct detailed inspections on all aspects of the street lights. Let the battery panels run in good conditions for a long time, to ensure the power generation capacity of the power station and create more economic benefits.

Solar panels, also known as “solar chips” or “photocells” and “solar cells”, are photoelectric semiconductor sheets that use solar light to directly generate electricity. A device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. In physics, it is called photovoltaic (Photovoltaic, abbreviated as PV), or photovoltaic for short. Solar panels provide electricity by absorbing sunlight, so the most important thing is to keep the light-receiving surface clean and check whether there are obstructions frequently. We have collected and sorted out some precautions for daily maintenance and inspection of solar panels, and we hope it will be helpful to everyone.

Check the surface of the solar panel to see if there is any crack. If a crack is found, please replace the solar panel in time.
Check whether the battery board connection wire and the ground wire are in good contact, and whether they are falling off.
Check whether there is heating at the junction of the combiner box, and whether the battery board bracket is loose or broken.
Check and clean up the weeds that cover the battery boards around the battery boards.
Check whether there are any coverings such as bird droppings on the surface of the battery panel, and clean it if necessary.
In windy weather, check the battery panels and brackets.
The battery panels should be cleaned up in time during heavy snowfall to avoid freezing and freezing on the surface of the battery panels.
In heavy rain, check whether all the waterproof seals are in good condition and whether there is water leakage.
Check the waterproof and tightness of the collector under the battery board to prevent water from entering.
