From the economic point of view, a meaningful and reliable energy yield prediction is indispensable for your prospected photovoltaic power plant. Amongst others, the energy yield is decisively influenced by the solar irradiation, the system layout of the photovoltaic power plant and the quality of the system components. As an accredited consultant, we provide meaningful as well as bankable and investor suitable energy yield expertises, which are based on internationally accepted methods and standards (e.g., German Solar Industry Association UVS working group “Quality Assurance for Solar Funds” - Commitment of Yield Experts). Your financial risk can already be minimized considerably in the planning stage.
Services in detail
- site visit, determination of the horizon line (if required), photo-documentation
- determination of the site-specific irradiance under consideration of the tilted module area
- plausibility check of the irradiance data with different sources (e.g., Meteonorm, DWD, Satel-Light, PVGIS, NASA, NREL, CM SAF,...)
- simulation of the expected energy yield (e.g., PVSYST, SolEm, Greenius) on the basis of hourly irradiance data under consideration of the system components and the system layout
- prediction of the performance ratio and specific energy yield
- determination of yield-reducing factors, e.g., pollution, mismatch, shadowing, temperature and inverter losses,...
- calculation of exceeding probabilities (P25, P50, P75, P90,...)
- banable and accredited irradiance and energy yield expertise/report: presentation of all results and underlying methods in report form
Additionally, we provide verifications and plausibilty checks of real operational data from existing plants under consideration of site-specific long-term solar irradiance data.
