Data Source and Methodology
Data and formulas are sourced from the NREL's PVWatts Calculator. All calculations are based strictly on these sources.
The Formula Explained
Output (kWh) = Solar Panel Capacity (kW) × Avg. Sunlight Hours × Efficiency (%)
Glossary of Terms
- Solar Panel Capacity: The power rating of the solar panel in kilowatts (kW).
- Avg. Sunlight Hours: Average number of sunlight hours per day.
- Efficiency (%): Efficiency of the solar panel in converting sunlight to electricity.
How It Works: A Step-by-Step Example
Consider a solar panel with a capacity of 5 kW, with 6 hours of sunlight per day, and an efficiency of 20%. The estimated output would be:
Output = 5 kW × 6 hours × 0.20 = 6 kWh
Frequently Asked Questions (FAQ)
What factors affect solar panel output?
Factors include panel capacity, sunlight hours, and panel efficiency.
How can I improve my solar panel's efficiency?
Ensure panels are clean, well-maintained, and installed at optimal angles.
