Solar AC power system is composed by solar panel
cells, solar charge controller
, power inverter and solar batter; but solar DC power system not include power inverter. In order to the solar power system can provide more power for the appliance. We should choose the parts depend on the appliance power needed.
1)Now let’s talk about the counting method base on the 100W output, use 6hour per day.
First, we should calculate the daily consumption of power/hours (including the loss power of inverter): if the inverter conversion efficiency is 90%, when the output power is 100w, then the actual power we need is 100W/90%=111W, if we count depend on condition using 5 hours per day. Then the loss of power is 111W*5hours=555wh.
Solar panel: we calculate by 6hours valid sunshine duration. Then considering the charging efficiency and
2). Loss when charging for the battery, the output power of solar panels should be 555wh/6h/70%=130w. 70% is the actual using power under the charging process.
