Photovoltaic yield reports

We can support the success of your project with the following reports.

Yield reports and yield estimates

A yield report for photovoltaic systems provides a well-founded forecast of the expected long-term energy yield and thus serves as a key basis for decision-making for investors, operators, and project developers. It is based on location-specific meteorological data and local conditions such as terrain, shading, or snow load, which are mapped in a simulation model and supplemented by additional calculations and empirical values. This results in a transparent assessment that is crucial for both the planning and operation of the system and for negotiations with banks, investors, and authorities.

Irradiation reports

Irradiation reports provide a reliable basis for further calculations, such as yield reports. We evaluate site-specific irradiation data at an early stage of planning, accounting for various sources. Thanks to precise long-term series and our many years of experience evaluating weather data, we produce professional, independent reports. This gives you reliable results that provide security and transparency for your projects right from the start.

Yield loss calculations

If a system was not in operation as planned, the lost yield for the affected period can be calculated precisely. This may be due to factors such as a delayed grid connection or prolonged system failures. The calculation is based on the potential system yield, determined from the individual system configuration and weather data for the period under review. You will receive the result in a clear report with a clear indication of the yield loss.

Performance check

To determine the performance ratio (PR) of your PV system, we review the measurement data and create a target/actual comparison. As with the calculation of our yield reports, the system-specific parameters are also taken into account. A summary report that objectively presents your system's performance and provides reliable evidence for your business partners. It is possible to consider the target and actual PR, as well as to validate an external PR calculation.
