Power calculation: The solar AC power generation system is composed of solar panels, solar panel charge controller, inverter and storage battery; the solar DC power generation system does not include the inverter. In order to enable the solar power generation system to provide sufficient power for the load, solar panel it is necessary to select various components reasonably according to the power of the electrical appliances. Take 100W output power and use 6 hours a day as an example to introduce the calculation method: First, solar panel calculate the watt-hour consumed per day (including the loss of the inverter): If the conversion efficiency of the inverter is 90%, solar panel then When the output power is 100W, the actual required output power should be 100W/90%=111W; if it is used for 5 hours a day, solar panel the output power is 111W*5 hours=555Wh.
Calculate solar panels: Calculate according to the effective daily sunshine time of 6 hours, solar panel taking into account the charging efficiency and charging process
