Thanks BeGreen - I honestly didn't know how they did it, but I know the company came well recommended, they are well established, and stand behind their work. Leakage from the mountings was/is not a major concern for me really. I'm more concerned about the system performing up to spec and as projected. Only time will tell if the production estimates work out to be on target - if it produces more than estimated that will be a nice bonus. The thing is that since this relies on the weather it will take some significant time before we'll know if it really will produce as anticipated. Anyway, so far it is a fun set of stats to follow. I'm out of town for a week - annoying in a way but perhaps good too as it will keep me from obsessing as much. Mix of weather expected, more clouds than sun though so not expecting a whole lot, better get used to that is it is getting into December after all. Now I just have to wait to get my first Mwhr collected so that I can sell an SREC... that's the next landmark for me. At this rate it will be a few months I suppose, but at least I have something to look forward to.
