Photovoltaics Common claculation formulas
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
Battery components are connected in series and parallel
1 Number of battery modules connected in parallel = Average daily power consumption of the load (Ah) / Average daily power generation of the module (Ah)
2 Number of battery modules in series = system operating voltage (V) × coefficient 1.43/module peak operating voltage (V)
Battery capacity
Battery capacity = Average power consumption per load day (Ah) × Number of consecutive rainy days/Maximum depth of discharge
