Hi all,
A few months ago I put up a few small amorphous panels. The were simply stuck down to a piece of plastic with double sided pads, and after about 4-5 months all the panels were ruined (the silver peeled off the back of the panels).
Anyway I have just purchased a larger panel, and I have made a good wooden frame for it, coated with yaught varnish. I have mounted the panel into the frame using silicon sealant, and now I was wondering what to do to protect the back of the panel. Do I give it a coat of yaught varnish, or spray it with lacquer? Is there anything wrong with coating the back of the panel like this? Afterwards, if I coat the back of the panel, I will run around it again with sealant to completely make the whole thing watertight.
Excellent site btw, I have been coming here for many months now before finally deciding to start my own little renewable energy project!
