Sound yield calculations for planning and evaluating PV systems

Service description

Based on highly precise weather and irradiance data we determine the long-term energy yield of your PV system while incorporating local conditions. The reports form the basis for the bank’s financing decision.


  • Procurement of weather data from at least two independent sources
    (Long-term monthly means of irradiance and temperature)
  • Conversion of average monthly values into hourly values using Synthesis processes
  • Taking into account local conditions such as number of days of snow, objects causing shading and the specific irradiance profile for the site with regard to low light characteristics
  • Specific system configuration is considered
  • Detailed time-step simulations for each subsystem
  • Summary Report containing all relevant information and result
    • Definition of safety margins
    • Details of the annual fluctuation range
    • Diagram of yields and percentile at selected

Your benefits

  • Faster and simpler financing decision by investors and banks worldwide
  • Reliable forecasting of system performance taking location-specific factors into account
  • Planning certainty for investors due to realistic estimation of expected yields
  • Extremely reliable Yield Reports through validation based on real operating data of more than 45,000 systems
