It's hit or miss. I purchased my solar panel and controller as a kit from an ebay store located in Quebec. This outfit: http://www.ebay.com/usr/solar-power-canada?_trksid=p2047675.l2559
If I were cruising full time I wouldn't cheap out on this. The truth is that I'm a weekend cruiser and this technology is a commodity. Three seasons now and I don't regret cheaping out on this one, the kit has served very well. Steve Suhana, C&C 32 Toronto
