Calculation formula: ring S = π (R?-r?), where ring S = surface size of the solar panel, R is the radius of the outer diameter of the solar panel, and r is the screen LCD.
The power output of solar panels is only related to the area, and the power output has a linear relationship with the area.
Content radius (note: the outer diameter of the LCD screen is 41mm, that is, r is 20.5mm). According to the test data and parameter display provided by the manufacturer, it is necessary to double the surface). after two 5530-8L modules are connected in parallel to meet the current 100uA size requirement. Ring S = π (R?-r?) = 2*55*30, calculated R = 50.21mm, that is, the outer diameter of the solar panel is 100.5mm.
Detailed information:
1. Wormcheck whether the panels are damaged, discover them in time and replace them in time.
2. Check whether the battery board connection wire and ground wire are in good contact and whether they fall off. Check for heat at the junction of the mixing box.
3. Check if the battery panel bracket is loose or broken. Check and remove weeds around panels blocking them.
4. Check whether there is a cover on the battery panel surface, check the battery panel surface for bird droppings, and clean it if necessary.
5. Evaluate the cleanliness of the battery board.
6. In windy weather, key inspections of panels and battery holders should be carried out.
7. On heavy snow days, the battery panels should be cleaned in time to avoid snow and ice on the surface of the battery panels. The temperature of the battery panels shouldt be detected and compared to the ambient temperature. for analysis.

The area of 15 kilowatt solar panels is 150 square meters. According to relevant information, the 15KW solar panel is composed of 60 255W photovoltaic modules, covering an area of about 150 square meters and generating an average daily power of 60KWH. Solar cells, also known as "solar chips" or "photovoltaic cells", are optoelectronic semiconductor sheets that use sunlight to directly produce electricity. Simple solar cells cannot be used directly as energy sources. To realize power supply, multiple solar cells must be connected in series, parallel and tightly sealed in the components.
