Yield Reports

Sound yield calculations for planning and evaluating PV systems

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.

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
  • Reliable Yield Reports through validation based on real operating data of more than 45,000 systems


  • Procurement of irradiance data from at least two independent sources (long-term monthly means)
  • Conversion of average monthly values into hourly values using Synthesis processes
  • Taking into account local conditions (e.g. snow and objects causing shading)
  • Specific system configuration is considered
  • Detailed time-step simulations for each subsystem
  • Summary Report
  • Definition of confidence level and P-Quantiles (P50, P75, P90)

Plant-specific pv production profiles for Power Purchase Agreements

Power Purchase Agreements (PPAs) have become increasingly important in recent years with regard to trading of solar energy and represent more than just an alternative to the previous "classic" feed-in tariffs.

In addition to energy supply companies, municipal utilities and grid operators, large corporates such as Amazon, Google, Facebook & Co. in particular represent an important pillar on the electricity consumer side. Within the framework of PPA tenders, the electricity consumers (off-takers) identify the suitable electricity producer in relation to their specific load profile. In the area of corporate PPAs, i.e. power purchase agreements between plant operators and corporates, the plant-specific power generation profile thus plays a decisive role.

For this reason, the PPA tendering process places special emphasis on a suitable hourly profile. Our independent team of experts will support you in this process by quickly and easily creating project-specific pv power generation profiles, also known as 8760 h profiles. A plant-specific hourly profile is also possible in combination with a bankable pv yield report or yield estimation.
