Calculating the power of solar cells:
1. Calculate the number of watt hours consumed per day, generally based on the conversion efficiency of the inverter which is 90%. When the output power is 100 watts, the actual output power required should be 111 watts; if used for 5 hours a day, the power consumption will be 555 W;
2. To calculate the power of solar panels, it is usually calculated based on 6 hours per day, because the charging efficiency and energy loss during the charging process are taken into account. , the energy loss is based on ten calculations. The output power of the solar panel should then be 130 watts.
