Solar Power System Sizing
Estimate the size of the solar panel system you need to offset your electricity bill. Calculates number of panels based on your monthly usage and local sun hours.
Key Factors
- Monthly Usage: Your average electricity consumption in kWh.
- Peak Sun Hours: The number of hours per day your location receives full sunlight intensity.
- Panel Wattage: The power output rating of the solar panels you intend to use (e.g., 400W).
System Losses
This calculator assumes a system loss factor of roughly 20-25% to account for inverter efficiency, wiring losses, and environmental factors like dust or temperature.
