that said, i've used their solar panels on my factory (more than 5 years ago), it had some problems and 80% of their panels failed, they said due to weather here causing the panels to deteriorate (rubbers getting harden) quicker, water seeped into electrical circuits and basically killing the panels. They've since replaced those panels, so far so good, crossing my fingers.
