Introduction How to calculate solar panel size and battery capacity Calculation of 8 hours of sunshine per day: Solar panel power = 5000/8/0.8 = 1250W Set the battery power.

How to calculate solar panel size and battery capacity

Calculation of 8 hours of sunshine per day:

Solar panel power=5000/8/0.8=1250W

Set the battery voltage to 48V

Battery capacity =5000/48/0.8=130A/H(48V)

Xiangtan, Hunan:

The efficiency of inverter is set to 96%

Average sunshine in Xiangtan, Hunan Time is 4.65 hours

Solar panel power calculation = 5000/0.96/ 4.65/0.8 = 1400 W (voltage = 65 V)

Set the inverter battery voltage to 48 V< /p>

Battery capacity = 5 000/0.96/48/0.8 = 135 A/H (48 V)

Inverter power, double the maximum power used
