Solar panel (Solar panel) is through the absorption of sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, most of the main material of solar panels australia for "silicon", but because of the production cost is large, so that it is generally used there are certain limitations. Compared with ordinary batteries and recyclable rechargeable batteries, solar cells are more energy-saving and environmentally friendly green products.
The life of the photovoltaic module is determined by its power generation efficiency, and the degree of combination of the PN junction and the purity of the silicon wafer determines the intensity of electricity generated by the solar panel under the same light irradiation, over time, the PN junction will continue to break, so that the efficiency will continue to decline, 15 years later the conversion efficiency is more than 90%, 25 years later will drop to about 85%, Therefore, the life of photovoltaic components is basically more than twenty years. In recent years, the development and use of new materials have made the life of solar panels increasingly longer, but some materials have not yet been put into daily use because of their high cost. Of course, in our daily life, reasonable inspection and maintenance of our solar panels can well extend the service life of solar panels. Then let's briefly introduce what we as non-professionals should do to check and maintain solar panels on a daily basis.
Daily inspection and maintenance of solar panels
1, check whether the panel is damaged, to be found in time, timely replacement.
- Check whether the connecting wire and ground wire of the panel are in good contact and whether there is any falling off phenomenon.
- Check whether there is heat at the junction of the junction box.
- Check whether the panel bracket is loose and broken.
5, check and clean the weeds around the panels that block the panels.
6, check the surface of the panel for cover.
- Check the bird droppings on the surface of the panel and clean them up if necessary.
- Identify the cleanliness of the panels.
9, strong weather should focus on the inspection of panels and supports.
- The panels should be cleaned in time on heavy snow days to avoid snow and ice on the surface of the panels.
11, heavy rain should check all the waterproof seal is good, there is no leakage phenomenon.
12, check whether there are animals into the power station to destroy the panels.
13, hail weather should be focused on the surface of the panel inspection.
- The temperature of the panel is detected and analyzed compared with the ambient temperature.
15, the problems checked out should be dealt with in a timely manner, analysis and summary.
16, to make a detailed record of each inspection, in order to facilitate future analysis.
- Make analysis and summary records and file.
