Annual Energy Production

About the simulation: Calculations based on declared annual degradation (-%/year). Default irradiance (1200 kWh/kWp/year) is an average - check your exact value using PVGIS. Actual production depends on location, orientation, shading, and installation quality.

°C

Cell temperature of 75°C is typical for rooftop panels on a hot summer day at full irradiance. Temperature coefficient -0.29%/°C means power drops by this percentage for each degree above 25°C.

What is albedo? Albedo is the fraction of sunlight reflected by a surface. Higher albedo (lighter surfaces) means more light reaches the back of bifacial panels, increasing total energy production.

Calculation: Bifaciality (-) × Albedo × 0.6 (view factor)

This calculator uses a simplified model with default albedo values and a ground coverage factor of 0.6. Actual gain depends on installation conditions, tilt angle, mounting height, and season. For accurate calculations, we recommend measuring albedo on-site.
