Utilize our Solar Panel Array Sizing & Kilowatt-Hour Calculator to accurately estimate the number of panels and total system wattage (KWp) needed for your home. Discover your potential daily and annual kWh generation, ensuring you meet your energy demands efficiently. Plan your sustainable future today!
Formula:
This calculator helps you determine the optimal solar panel array size (in Watts peak, Wp) and the estimated energy generation (in Kilowatt-hours, kWh) based on your energy consumption and local sunlight conditions.
Key Variables:
- ADEC: Average Daily Energy Consumption (kWh/day)
- PSH: Peak Sun Hours (hours/day)
- IPW: Individual Panel Wattage (Wp)
- SL: System Losses (%, e.g., inverter efficiency, wiring, dust)
Formulas Used:
1. Required System Wattage (Wp): `( (ADEC × 1000) / (1 - SL / 100) ) / PSH`
2. Number of Panels: `ceil(Required System Wattage (Wp) / IPW)`
3. Estimated Daily Generation (kWh): `(Number of Panels × IPW × PSH × (1 - SL / 100)) / 1000`
4. Estimated Annual Generation (kWh): `Estimated Daily Generation (kWh) × 365`
