Pump Sizing Formula
Hydraulic Power (W) = Q x H x 9.81 / 3600
Q = Flow (L/hr), H = Head (m)
Pump Power = Hydraulic Power / Efficiency
Array Size = Daily Wh / Sun Hours / 0.8
Typical Pump Efficiencies
| Pump Type |
Efficiency |
Best For |
| Submersible | 50-65% | Deep wells (50-600ft) |
| Helical Rotor | 40-60% | High head, low flow |
| Surface Pump | 55-70% | Shallow wells (<25ft) |
| Centrifugal | 60-75% | High flow, low head |
