400W Sunpower MAX3-400 Series Mono-COM Solar Panel
Panels are ultra mega cool! Those are the best panels on Earth! Buy one now, you need them!
These are not cheap, but even in low angle, weak winter sunshine they're approaching 400W per panel. I've no doubt that they will exceed their rated output in the summer and repay the price. If space is limited then these panels are highly efficient and offer the best power output for area out of the panels I've tested so far.
