Measuring unit with black protective housing for field testing of solar cells and PV modules.

Reliability of photovoltaics

We evaluate the reliability of new solar cells, materials, and PV modules under real-life conditions—across laboratory settings, outdoor field testing, and with custom module designs.

Durability and energy yield reliability in photovoltaics

Long-term durability and energy yield reliability are key factors for the economic operation of photovoltaic systems. At ISFH, we investigate how new solar cells, PV module components, and materials perform under real operating conditions—through outdoor field testing and artificial accelerated aging.

We are developing cost-efficient imaging-based characterization methods to enable fast quality control of PV systems, both in the field and in laboratory environments.

New innovations in PV module technology—such as perovskite-based solar modules—introduce additional challenges. That’s why we are continuously advancing our characterization and testing methods to meet the evolving demands of emerging technologies.

Reports from IEA PVPS TASK13: Reliability and Performance of Photovoltaic Systems

The overall objective of Task 13 is to improve the operation and reliability of photovoltaic energy systems and, as a consequence, to improve their electrical and economic performance.
