Superior Quality Panel This Solar panel is awesome. The quality of build, fit and finish is superior, and I would definitely buy more. I have this connected to a micro grid inverter, and It’s almost 80% efficient which is not what I was expecting, compared to the 65% to 70% efficiency that other folks have been seeing with their panels…. So far it has far exceeded my expectations ….*************Update***************************I’m changing my view towards this panel, because i don’t feel it’s worth the extra money, and it’s efficiency is way lower than even a 240 watt Poly panel. The look & finish are great on this panel, and that’s why I didn’t reduce my rating to only 1 star, but this panel should be rated way lower than 250 watts…I have now purchased 2×240 watt Poly panles that outperform this panel in any light condition, and they cost almost 1/2 as much …This panel is not even on the California list of approved panels for rebates, because I’m assuming is not…
