Thanks for the link Carter! I see the cell efficiency is 19%, so I guess it is not SunPower cells.
Considering walk-on panels: this is definitily something I will need for my project. I didnt know that rogid panles are more robust, I will check out some rigid panels. What about this idea: cover flexible panels with plexi glas, al ittle air gap between the panles and the glas, and cooling system... Too much light loss due to refelctions/absorption? A bad idea..?

Bendick,They are probably all the same thing with different prices from different vendors. Looks like the Renology panel to me and you can order them on their website for $199 right now. 100W Monocrystalline Bendable Solar Panel | Renogy Store Free shipping in the US too but it shouldn't cost that much more to ship across the pond. Not if you're getting a couple of them anyway.I've seen several vendors with similar products and I wouldn't be surprised if Grape just brand labels it and it's made in the same factory in China as Renology. Looks like it's at least made to the same specs using the Sunpower cell anyway.I think the light weight aspect is worth a 100% percent premium, if you need to lower your center of gravity on the boat for stability but if you don't I'd just get a rigid panel. Probably more durable. I'll be buying 400 Watts from Renology soon for my dinghy project but not sure I'd do it if I had to spend $1600. $800 is bad enough but I think my dinghy might capsize in rough seas with rigid modules.Those big heavy lead acid batteries in the bilge will help but it will still be much more stable with the laminate panels.Capt.

No it is a simply request for you to supply evidence for an absurd statement:"The majority of PV panels are made in china, these days.The std efficiency these days is around 20%."
I am simply asked you to find a single link to a single Chinese Panel that is 20% efficient that does not use SunPower cells. Who knows you might even be able to find one or two. I am not asking you to prove that the "standard" Chinese panels is 20% efficient. Which is what you claimed.The average US and Japanese panels are not that efficient. Only the very high end of the consumer panels are in that range, with a price premium on them for being the top of the line in efficiency.If there are sooooooo many Chinese 20% efficient panels out there it should only take you a few minutes? Please enlighten the group. Boats have very limited space for panels it would be incredibly useful, to have this list of 20% efficient cheap Chinese panels.I will start the list off with two companies that make panels with SunPower Cells that are 20% efficient and are reasonably priced:Now your turn you just need to find one panel......One little panel.

The std efficiency these days is around 20%.
