Power generation solar panel power calculation

The solar AC power system is composed of solar panels, charge controllers, inverters and batteries. The solar DC power generation system does not include inverters. In order for the solar power system to provide enough power for the load, it is necessary to use it. Electrical power, a reasonable choice of the following parts to 100W output power, using 6 hours a day, for example, to introduce the calculation method:

1. First calculate the number of watts consumed per day (including inverter losses): If the conversion efficiency of the inverter is 90%, then when the output power is 100W, the actual output power should be 100W / 90 (%) = 111W; if using 5 hours a day, the power consumption is 111W * 5 hours = 555Wh.

2. Calculation of solar panels: According to the daily effective sunlight time of 6 hours, and then consider the charging efficiency and the loss of the charging process, the output power of solar panels should be 555Wh / 6H / 70% = 130W of which 70% Is the actual power usage of the solar panel during charging.
