Sinovoltaics said that since 2020 its AI-driven SELMA (Sinovoltaics Electroluminescence Mass Analysis) tool has been used by “all” the Tier-1 solar manufacturers in Asia. The company claims that SELMA tests 100% of the modules that a buyer purchases and can assure “Zero Risk” of microcracks and other cell defects.
The technology is underwritten by a quality guarantee from German insurance company Munich Re, which Sinovoltaics says is an industry first.
Indeed, the majority of testing processes rely on taking a sample from a batch of modules and using EL testing to gauge the proliferation of any defects. This is largely due to the time and price constraints of testing every single module, especially as the price of the products continues to fall.
Sinovoltaics claims that it tested 4 million modules in 2023 and that Tier-1 facilities showed a replacement rate of around 1-3% on average.
“100 percent module inspections is the only way to ensure high performance solar projects,” said Dricus de Rooij, co-founder and CEO of Sinovoltaics. “
