// SOLAB: Photovoltaic Testing Laboratory
Our services and research aim at ensuring the most economically efficient use of long-life and low-cost PV modules and systems.
PV modules based on all technology types are tested in ZSW’s Solab photovoltaic testing laboratory. Solar simulators, climate chambers and systems for mechanically and electrically loading modules are available for standard tests, customer-specific tests and studies accompanying development.
The services provided by the Solab photovoltaic testing laboratory are supplemented by outdoor measurements at the Widderstall test facility. The combination of indoor and outdoor test methods and the ability to correlate the results are unique. Based on the results we produce expert assessments covering various aspects of the module characteristics, quality and ageing.
Solab offers the following services to industry and users:
- Precise test methods for nominal output, energy yield and long-term stability
- Linkage between open air measurements at the module and system level to accelerated ageing tests in the laboratory
- The development of measuring and testing methods for new-style module concepts
- 30 years of experience in photovoltaic materials research
