Solar yield calculations are based on real localised irradiance data, factoring in the exact orientation, tilt, and shading conditions entered during the design. The ROI model incorporates current energy tariffs, applicable subsidies, and hardware degradation curves to build a 25-year projection. For the Dutch market, additional levers are available including feed-in cost modeling and salderingsregeling phase-out scenarios. The methodology is consistent across every consultant, so the numbers your team presents reflect the same underlying model every time.
