1.Conversion efficiency
η= Pm (peak power of the cell)/A (area of the cell) × Pin (incident light power per unit area)
Among them: Pin=1KW/㎡=100mW/cm².
2.Charging voltage
Vmax=V amount×1.43 times
3. Battery components are connected in series and parallel
3.1 Number of battery modules connected in parallel = Daily average power consumption of the load (Ah) / Average daily power generation of the module (Ah)
3.2 Number of battery modules in series = system operating voltage (V) × coefficient 1.43/module peak operating voltage (V)
4.Battery capacity
Battery capacity = Average power consumption per load day (Ah) × Number of consecutive rainy days/Maximum depth of discharge
5.Average discharge rate
Average discharge rate (h) = number of consecutive rainy days × load operating time/maximum discharge depth
6. Load working time
Load working time (h) = ∑ load power × load working time / ∑ load power
7.Battery
7.1 Battery capacity = average load power consumption (Ah) × number of consecutive rainy days × discharge correction coefficient/maximum discharge depth × low temperature correction coefficient
7.2 Number of batteries in series = system operating voltage/battery nominal voltage
7.3 Number of batteries connected in parallel = total battery capacity/battery nominal capacity
