     Solar energy AC power generation system is composed of solar cell board, charge controller, inverter and accumulator, and the solar power system does not include inverter. In order to make the solar power system can provide enough power for the load, it is necessary to select each part rationally according to the power of the electric appliance. below to 100W output power, use 6 hours a day as an example, introduce the calculation method:Solar Panel
     First of all, calculate the number of Watts per day (including the loss of inverter): If the inverter conversion efficiency is 90%, then when the output power is 100W, the actual need for output power should be 100w/90%=111w; if 5 hours per day is used, the electricity consumption is 111w*5 hour =555wh. Calculation of solar panel: According to the daily effective daylight time for 6 hours, and then considering the charging efficiency and the loss during the charging process, the output power of the solar panel should be 555wh/6h/70%=130w. of which 70% is the charging process, the actual use of solar panels power.Solar Panel
     Solar panels: Solar panels are the core of solar power systems and the most valuable part of solar power systems. Its role is to convert the sun's radiation capacity to electricity, or to the storage battery, or to promote load work. The quality and cost of the solar panel will directly determine the quality and cost of the whole system.Solar Panel
     Solar Controller: The role of the solar controller is to control the operating state of the whole system, and the battery has played the role of overcharge protection, over discharge protection. In the large temperature difference place, the qualified controller should also have the function of temperature compensation. Other additional functions such as the optical control switch, the time control switch should be the controller's option.Solar Panel
