We currently have 8 1x20 Enersol EPDM panels on a (totally) flat roof. They have worked great for 8 of 10 years and enabled use of our 256 sqft pool from mid April to mid October using a heat pump as a backup heat source. Unfortunately, the panels started to leech black particles around two years ago, especially when opening the pool. This is, apparently, one negative of synthetic rubber panels. Has anyone else experienced this and managed a fix? Assuming there is no fix I have to replace them. I have been looking at fixed panels from Techno-Solis and a product called Powerstrips. Pricing is roughly the same so that is not an issue.
- the powerstrips come in 8 1x20' just like my Enersol panels but hooking them up to the header and footer using glue seems tricky and then you have to join the 1 foot headers together. Has anyone replaced Enersol panels with these? Any install advice?
- the Techno-Solis come in fixed sizes, there are local installers but I worry about the freeze issue on a flat roof. Putting them at an elevated angle using a frame may not be an issue due to raccoons.
Am at a bit of a loss in deciding. Any thoughts, advice, etc...?
