Joel Had thought (briefly) about heat mitigation, but like you I enjoy a 5 month season here in the Toronto area, and I doubt it's the same issue it might be in South Florida or elsewhere. To Josh's point - the air is moving under the bimini. I'm more concerned about the weight on the unsupported fabric over time.
Worthwhile? Dunno yet. I haven't tested the setup, but really it depends on your objective. The 33ii has space constraints for both panels and batteries, and as a result my expectation is to extend the time between charging, not to eliminate charging. We'll see. In theory, If I were able to accommodate another 50w of reliable generation, windstar could be 100% off the grid. Cost of the panel and controller is around C$500+ (you can verify on Renogy.ca.) Battery choices are another consideration, and can get spendy quickly.. I bought two lithium group 35s totalling 220ah. if you click around on that blog you'll see further documentation and all the associated arithmetic and (excessive...lol) reasoning. This area is new to me, I had a lot of input from experienced folks on the list and much is shared there. This includes an inventory of the power consumption by item on Windstar which may save you (or your wife) some time.
