My particulars are still the same Postal address 35 Wds Street,Baulkham Hills NSW 2153,thanks

Shane, if it is one of new tech, sardonic panels with the wiring behind the pv cells, then care needs to be taken. On the EBay listing for these,, no matter where you buy them, it says not to fix directly into any surface due to heat. That is probably right although if it was on a metal surface that surface might act like a heat sink and actually dissipate the heat that is generated. I also bout same panel, but in a frame with glass, is, same pv cells. The heat build up for them was tremendous too. In fact even though rated at 21.6 v the output was 22.5+ for a while then as the got hot dropped down to sub 21v. Had to return those panels too because many of the pv cells had cracks. This might have contributed to heat. Vicoffroad had no prob giving refund and paying for postage. But none of these people can inspect panels before they send to make sure they're OK. The panels are shipped from warehouse and the seller doesn't actually handle them.
Finally, be sure you don't void their warranty by connecting two together or gluing down. Read description very carefully.

Finally, be sure you don't void their warranty by connecting two together or gluing down. Read description very carefully. I had intended to see a light weight frame for the flexi panels I had and use them free standing, maybe with lightweight aluminium backing to give strength. Frankly, hard to recommend these panels with the issues and not being able to connect without voiding warranty.

Thanks for the reply I am mounting it to a aluminium hard top on a boat do you think this will be ok? I was hoping to silicone it directly to this. As the panel comes with no instructions I was unsure how to mount it. Cheers
