Hi Tanja

If there a Tier 1 Panel called EC Solar its a Bankable panel. And the factory was like an operating room, As we do regular trips out there.

We tested this panel against Solar world and the EC Solar panel and the EC panel will out perform the Solarworld panel in UK conditions and Tested at Warwick University.

So the answer is if its a Tier 1 panel you should be in safe hands.
