Bridging the gap between research and industry, the ZSW (Center for Solar Energy and Hydrogen Research) is one of the leading research institutes for renewable energy. We cover the complete value chain in the areas of photovoltaics, energy systems analysis, regenerative fuels, storage technologies and fuel cells: from materials development to the development of manufacturing techniques and components, and including pre-production investigations, systems applications and quality as well as safety tests. Application-minded thinking makes us a flexible partner for companies of any size. With about 260 employees, we currently generate a turnover of about 30 m. Euros.
The ZSW PV module test laboratory Solab tests performance, quality and reliability of PV modules especially in customer-specific tests: stress by temperature and humidity in climate chambers; UV-light; potential-induced degradation (PID); screening and evaluation of backsheets; light-induced degradation (LID, LeTID); performance measurement, also after pre-conditioning for stabilisation especially for thin-film PV; mechanical load, EL, thermography.
Outdoor testing facility for performance and yield measurements of PV modules and small systems with high-resolution acquisition of relevant electrical and meteorological data: since 1988 near Merklingen.
Development and application of testing methods: characterisation of PV modules and systems; long-term module stability; methods for accelerating loss and ageing of modules; correlation of laboratory and outdoor measurements; collaboration in standardisation committees.
Systems technology and grid integration of PV systems: PV storage systems; energy management; optimisation for personal use; smart grids on distribution grid level.
Consulting for manufacturers, investors, banks, project developers, operators: system measurement and acceptance; yield prognosis and site assessment; technical due diligence reports, factory inspections, solar and wind power output forecasts. Testing facility for wind turbines in mountainous-complex areas near Geislingen, Germany.
