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.

‘We’re seeing that manufacturers have tried to remove materials, remove costs from those modules, to cut their losses, and that presents reliability risks,’ says Tristan Erion-Lorico. Image: Kiwa PVEL ...

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 ...
