Solar Panel Calculator
The Formula
The formula for calculating solar panel output is:
\[E = P \times H \times \eta\]
Where:
- E: Energy output (kWh/day)
- P: Panel wattage (kW)
- H: Peak sun hours per day
- η: System efficiency
Calculation Steps
- Determine the peak sun hours for the given location
- Convert panel wattage to kilowatts
- Estimate system efficiency (typically 75-80%)
- Multiply panel wattage, peak sun hours, and system efficiency
Example Calculation
Let's calculate the daily energy output for a 300W panel in Los Angeles (5.5 peak sun hours):
- P = 300W = 0.3 kW
- H = 5.5 hours
- η = 0.75 (75% system efficiency)
- E = 0.3 × 5.5 × 0.75 = 1.24 kWh/day
