Quality & Reliability

CIS modules are built for long-term performance in actual operating conditions.

Reliability is paramount. Your solar modules need to perform for the duration of their warranty period, if not longer.

We ensure reliability and standardization in technology. Our CIS modules are manufactured using fully automated lines in Japan based on strict quality-control protocols. Our lines have also been tried and tested since we began production in 2007, and are periodically technically audited by independent third parties such as Black & Veatch.

And at the module level, our technology has passed multiple additional durability tests.
