Thanks for the pictures, but more details please. What panel? What are you running off it? Why so much as I was thinking 200-300 would run a small 12volt refrigerator, lights, pump, etc? That system of flex panels and adhesive seems to be a great option- very "stealth" and clean. How to get the wires thru the roof and manage the cables inside. Batteries? Where? How much capacity?Three 200w flexible panels mounted with Sikaflex.

My understanding was one product was cupping and was recalled and the problem was widely reported but has not been seen in other panels from that manufacturer and never from the rest. I did due diligence on google but perhaps you can provide counter evidence?? I certainly would not want to spend this money and be wrong. BTW the mono-chrystaline flex panels are so much more efficient the added heat loss still puts them above the glass and Al ones. They are a bit more spendy by 1/3. This has been reported on this forum before.I'm waiting for my rack....cut..... I was going to get these flexible ones but where I park gets really dirty and those panels tend to form little cup recesses that dirty water will collect and dry lowering the capacity unless you keep them clean.
I feel a little weird about sticking flexible panels on the roof. What if I want to clean under the panel or if debris like pine needles or leaves get stuck in the void areas under the panel?Three 200w flexible panels mounted with Sikaflex.

I plan on using the same panels but thought of sticking them to the same size aluminum sheets and using low 'L' brackets with pins in order to easily remove the panels for any reason.
Any thoughts ?
Typically, yes they do have a shorter life than their glass counterparts. However, mine are Sunpower Monocrystalline cells, which carry a 25 year warranty. That is for the cells. The assembled panels I purchased carry a 15 year warranty. This is because the assembly is sometimes to blame for panel failures.Don't the flex panels have a much shorter life?
I thought I read that when doing research on pv
Mojo, why do you say MPPT are better? Better for gel batteries that need to charge slower or better for all batteries?I must have had old info. The solar controller is a major factor in efficiency, MPPT ones are better but pricey.
