A. IF 12V SUBMERSIBLE PUMP WILL BE USED.
Build Summary (12V Setup, 8h/day runtime)
| Component | Recommended Spec |
|---|---|
| Solar Panel | 200W, 12V or 18V nominal |
| Battery | 12V, 70Ah deep cycle |
| Controller | MPPT, 20A |
| Pump Load | 5.4A, 64.8W |
| Fuse & Wiring | 10–15A inline, 12–14 AWG |
B. IF 24V SUBMERSIBLE PUMP WILL BE USED.
Setup Summary (24V Pump, 8h/day)
| Component | Recommended Spec |
|---|---|
| Solar Panel | 300W (1x300W or 2x150W) |
| Battery Bank | 24V, 45–60Ah (2×12V in series) |
| Controller | 30A MPPT |
| Pump Load | 3.8A, 91.2W |
| Wiring | 10–12 AWG |
| Fuse | 10–15A inline |
Recommended on Why the 24V Setup is better & efficient:-
- Lower current = less heat & voltage drop
- Smaller wires
- Better for expansion (add more panels or battery capacity later)
- More efficient for same job compared to 12V
