Solar Panel Production Calculator
Calculate the potential electricity production of your solar panel system based on total area, efficiency, solar radiation, and performance ratio (PR).
The calculation is based on the formula E = A × r × H × PR. A: Total solar panel Area (m²), r: Solar panel yield or efficiency (%), H: Annual average solar radiation on tilted panels (shading not included) (kWh/m²), PR: Performance Ratio. The performance ratio evaluates the quality of a photovoltaic installation (losses due to cables, inverter, temperature, etc.) and is generally accepted as 75% (usually between 70% and 80%).
This tool is designed for educational, informational, and preliminary planning purposes only. In real-world applications, actual energy output may vary significantly due to shading, weather patterns, panel orientation, temperature degradation, and equipment aging. Please consult an energy professional for precise calculations.
