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 ...

‘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 ...

Against the backdrop of the global solar PV industry’s accelerated transition to high-efficiency N-type modules, parking lots, as one of the core application scenarios for distributed PV, feature low ...
