☀️ Solar System Calculator
Estimate your solar PV capacity, number of panels, and required battery storage based on your home load.
| House Load (kW) | |
|---|---|
| Average Hours per Day | |
| Peak Sun Hours | |
| System Efficiency (0–1) | |
| Panel Wattage (W) | |
| Battery Voltage (V) | |
| Inverter Efficiency (0–1) | |
| Depth of Discharge (DOD, 0–1) | |
| Autonomy (days) |
Formulas used:
- Daily Energy (kWh) = Load × Hours
- PV Capacity (kW) = Daily Energy ÷ (Sun Hours × Efficiency)
- Panels = (PV Capacity × 1000) ÷ Panel Wattage
- Battery Wh = (Daily Energy × 1000 ÷ Inverter Efficiency) × Autonomy ÷ DOD
- Battery Ah = Battery Wh ÷ Battery Voltage
