Solar panel capacity design is very important, and the size of the capacity ultimately reflects the amount of solar energy resources that can be used. The design of solar panel capacity is very simple. The capacity of solar panels mainly refers to the storage energy of solar panels. The design of solar panel storage capacity is mainly concentrated on the intensity of sunlight during the day and the number of days of sunshine. During the period of time with many days of sunshine and strong solar luminosity, the storage capacity of solar panels is often very strong.

In addition, the capacity of solar panels must also consider the changes in the atmospheric environment. The temperature changes with the change of altitude. In the stratosphere, the temperature changes continuously decrease with the increase of altitude. Solar energy mainly acts below the stratosphere, so the capacity design of solar panels also decreases with the increase of altitude. In addition to considering the changes in the temperature in the atmosphere, the capacity design of solar panels must also consider the final angle of sunlight. The final power generation of solar panels is different for different angles of sunlight. For this reason, the final angle of the sun must be fully considered in the design process of solar panels. The angle design is different in spring, summer, autumn and winter in a year.
