Inventec Energy Corp. recently passed TUV's long-term sequential test for solar modules, becoming one of the only three module manufacturers in the world that have accomplished the feat.
“Photovoltaic modules play an extremely important role in solar power systems,” Inventec said. “Ensuring the module's long-term operations amid harsh and inclement weather conditions is critical in the design and manufacturing process.”
According to Inventec, the IEC 61215 and IEC 61730 certificates have become somewhat basic for manufacturers amid continued progress in module manufacturing. The long-term sequential test conducted by TUV has raised the bar significantly for module makers, who need to test their products for 2,000 hours for heat/humidity resistance, double the 1,000 hours in previous tests. Meanwhile, the number of thermal cycling tests was raised from 200 in the past to 400, while humidity/freeze tests from 10 to 40. The entire testing period has been extended from 2.5 months to six to eight months.
Inventec said it is glad to announce that its modules passed the test, with a power loss rate of merely 10 percent in spite of the extremely inclement weather conditions the modules were put under. Passing the test means that Inventec modules can withstand harsh climatic patterns and still give a high performance. Using these modules can help power generators increase yield rates, it said.
