According to the standards of International Electrotechnical Commission (IEC), static mechanical load test examines PV modules’ ability to withstand snow and wind loads.

As climate change exacerbates, PV modules are exposed to extreme cold weather conditions. It is important for modules to be able to face the challenges.

Seraphim, together with TÜV SÜD, conducted the mechanical reliability test on the 28mm-frame lightweight modules under extreme low-temperature conditions.

The static mechanical load test of 5400 Pa at front side and 2400 Pa at rear side was conducted under extreme low-temperature of -40℃ and 4-clamp installation conditions.

The results show that the modules maintain a good appearance without severe cracks. The modules have also passed the insulation and wet leakage tests with less than 5% power attenuation.

“The result has proven that even under extreme low-temperature conditions, Seraphim’s 28mm-frame lightweight modules are safe and reliable,” said Seraphim in the statement.

“Based on over a decade of research and development (R&D) and technological experience, Seraphim has been committed to innovation to improve the performance of PV modules and better serve clients with diversified demands, ” said Polaris Li, President of Seraphim.

Seraphim has a combined manufacturing capacity of 7.5 GW globally. To date, more than 14GW of its products have been installed in over 40 countries worldwide, said the company.
