Energy Rating and Yield Measurements for PV Modules

Energy Yield Measurements for PV Modules and PV Power Plants

Our solar energy yield services boost confidence in your PV products

Linear Performance Loss Analysis | TÜV Rheinland
We provide comprehensive services in these four main categories.

Accurate energy yield measurements of real productivity and reliable performance assure investors and customers that your PV modules are up to the task.

We offer broad testing of PV modules ranging from straightforward comparative energy yield measurements to long-term degradation studies. Our comprehensive Linear Performance Loss Analysis provides a differentiated impact quantification of factors including but not limited to temperature, low irradiance and angle of incidence. Photovoltaic products that undergo our more specialized assessments are able to earn an Energy Yield Rating Label and test mark.

Having worked with the solar industry since its infancy, we are uniquely positioned to thoroughly and precisely assess state-of-the-art PV modules. We provide you the expert knowledge you need to specifically benefit your PV power plant.

Energy yield rating – moderate climate | TÜV Rheinland
Our energy yield outdoor testing locations

This Energy Yield Rating Label shows the exemplary rating show the exemplary rating based on data sets related to a moderate climate and the module’s performance, in Cologne. Further data for module benchmarking are subtropical, hot-arid and semi-desert climates, generated from TÜV Rheinland operated test-sites.

Reliable and high-performance PV power plants with our energy yield measurement services

Our PV module energy yield measurement services are useful to players across the solar industry. Our accurate assessments and Energy Yield Rating Label help PV module manufacturers effectively demonstrate the suitability, performance and reliability of their products. We verify the unique technological improvements of individual manufacturers for increased success in competitive markets. We provide EPC’s with the means to test supplier products beforehand and to choose the right PV technology with the highest yield for their projects. Research and development institutions also benefit by gaining insights that they can use to design new and innovative technologies.
