Our guaranteed energy yield offers you up to 20 years of secure energy. For you this means: The energy performance agreed upon between you and S.A.G is always valid. That's something you can rely on. Your goal is our goal: a trouble-free, optimally configured system with maximum performance. And this is how it's done: We calculate the expected power yield for the entire term taking all relevant factors into account. This calculation represents the performance of the photo-voltaic system over the entire term and forms the basis of the contract.

Now it only depends on the weather ...

For a 140kW PV system we guarantee the calculated energy yield of 145,600 kWh / year. Only two factors can reduce the yield:

  • The difference between the annual solar irradiation in the previous year and the long-term average solar irradiance of 1,104 kWh / m²
  • A natural aging (degradation) of 0.5% / year

Our power yield guarantee is supported by a bonus/penalty agreement in view of the Full-Service-Flat-Rate
