256 square meters.
. The size of space station solar panels varies between space stations and their designs. The dimensions of the solar panels on the International Space Station (ISS) are 23 meters by 11 meters, for a total area of 256 square meters. The solar cell wing used by China's Tiangong space station has a wingspan of 67 meters and an area of 110 square meters.
How many watts does a solar panel with a length of 40 cm and a width of 60 cm have?
Calculation formula: ring S = π (R ?-r?), where S ring = surface size of the solar panel, R is the radius of the outer diameter of the solar panel, and r is the LCD screen.
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, c'i.e. r is 20.5 mm). According to the test data and parameter display provided by the manufacturer, it is necessary to double the area). after two 5530-8L modules are connected in parallel to meet the required current 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. Check 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 surface of the battery panel, check for bird droppings on the surface of the battery panel, 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 must be detected and compared to the ambient temperature. for analysis.

36 watts. The conversion efficiency of solar panels is between 15% and 20%. So, for a solar panel 40 cm long and 60 cm wide, with an area of 0.24 square meters and a conversion efficiency of 15%, the output power is: 0.24 square meters multiplied by 1000 watts per metersquare multiplied by 15% equals 36 watts. Therefore, the output power of a solar panel 40 cm long and 60 cm wide is approximately 36 watts.
