Calculation Of Solar Panel Power

The solar AC power generation system is composed of a solar panel, a charging controller, an inverter, and a storage battery; Solar DC power generation systems do not include inverters. In order for a solar power generation system to provide sufficient power for the load, it is necessary to reasonably select various components based on the power of the electrical appliance. Taking 100W output power and 6 hours of use per day as an example, the following calculation method is introduced:
First, calculate the watt-hours consumed per day (including the loss of the inverter): if the conversion efficiency of the inverter is 90%, then when the output power is 100W, the actual required output power should be 100W/90%=111W; If it is used for 5 hours per day, the output power is 111W * 5 hours=555Wh.
2. Calculation of solar panels: Based on the daily effective sunshine time of 6 hours, and considering the charging efficiency and losses during charging, the output power of solar panels should be 555Wh/6h/70%=130W. Of these, 70% is the actual power used by the solar panel during the charging process.
