A research group in Japan identified a correlation between damp heat test of 1,000 hours to 3–6 years of field exposure in humid areas and changes in acetic acid concentration in photovoltaic modules.

“Four years ago, that was at 50% and it’s steadily increased since,” said Tristan Erion-Lorico. Image: Kiwa PVEL. A total of 83% of module manufacturers have had at least one test failure in the Kiwa ...

The reliable performance of PV modules is heavily influenced by the climate conditions in deserts, which include factors such as irradiance, temperature, humidity and dust soiling. Image: DEWA R&D. A ...

The Renewable Energy Test Center (RETC) released its 2024 PV Module Index report, evaluating the reliability, quality, and performance of solar panels. Solar modules are put through a variety of ...
