How sizing works
The solar sizing formula
Your system size is your daily energy use divided by the peak sun hours where you live. In Punjab that’s roughly 5 hours a day — so a home using 20 kWh a day needs about a 5 kW system once losses are included.
- 1Estimate your daily energy need (kWh) from your appliances or bill.
- 2Check local peak sun hours (≈5 h in Lahore).
- 3Divide, then allow ~20% for heat, dust and wiring losses.
- 4Pick panels, inverter and batteries to match.
