Hi,
I want to put some Solar-Panels on the Roof of my Fiat Ducato. Because the weight really matters to me (need to stay under 3,5t), I'm thinking about using flexible Panels. Because Will strongly recommends the CIGS Modells I would use these.
It seems like they are only available on China Shops right now. (for Europe)
What do you think about these CIGS Flex-Panels? Have anyone already one of these? They are available in sizes up to 560w but for me the 90w would fit best. With 1-1,5€/W they are also not too expensive.
But because it's mounted directly on the surface of the roof, it's getting much hotter and because of that the efficiency will drop much more compared to the Glass Panels with an Air-Gap between, right? Also I guess it's getting hotter inside the Van because of that?!
But I saw a Tutorial about putting "Twin-wall sheets" between the Panel and the roof for some airflow. How much of the heat Problem is getting solved with this mounting method?
Another big down point is the efficiency/size. Only 3x90W is fitting on my roof, with overlapping Glas-Panels it would be 3x 150W. But I think 270w is enough for us.
Thanks a lot and sry for my bad English
