Podaj dzienne zapotrzebowanie na wodę, całkowitą wysokość podnoszenia i czas pracy. Porównaj wynik z dokumentacją pompy.
Sposób obliczania
Hydraulic energy kWh = 1,000 × 9.81 × volume m³ × total dynamic head m / 3,600,000. Electrical energy = hydraulic energy / combined efficiency. Power = electrical energy / pumping hours. Array kWp = electrical energy / [sun hours × (1 − losses)].
Total dynamic head includes lift, friction and required discharge pressure expressed as water head. Match a real pump curve to the calculated flow and head. The energy-sized array does not guarantee instantaneous motor power, startup or flow during low sunlight; check the drive, array and water storage together.
