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:
1. The number of watts hours consumed per day (including the loss of the inverter) should be computed first: if the conversion efficiency of the inverter is 90%, then when the output power is 100W, the actual need for output power should be 100w/90%=111w; If you use 5 hours per day, the electricity consumption is 111w*5 hours =555WH.Solar Panel
2. Calculate 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 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
