How This Works

Solar energy production estimation relies on understanding the relationship between surface area, efficiency, and available sunlight.

  • System Capacity: Calculated as Area (m²) * Efficiency (%). This assumes standard test conditions (STC) of 1000 W/m² irradiance.
  • Annual Production: Calculated as Capacity (kW) * Insolation (kWh/m²/day) * 365 days * Performance Ratio.
  • Performance Ratio (PR): A coefficient (usually 0.75 - 0.85) that accounts for real-world losses due to wiring resistance, inverter inefficiency, panel soiling, and temperature degradation.
