The Nuenergy offer is free other than one or two added costs. In my cast $120.00 extra because I have a tiled roof. Clearsolar are about $3000.00 more. They use BP solar panels, Nuenergy use CEEG. Both are guaranteed for about the same time but I expect in say 15 years it’s going to be easier to find BP solar than CEEG maybe. That said you’re paying $3000.00 more for BP.
The return on investment here is what does having 1 KW of solar panels on the roof do for me. It cuts down on your power bill and perhaps earns money via back feed. The time required to repay $120.00 vs. $3000.00 investment is significant. Add to that the current solar panel technology today will perhaps be comparable to a 40 MB MiniScribe HD in 1982 @ $700.00 vs. a Seagate 1 TB in 2009 @ $200.00. I suspect by the time the cheaper panels fail the technology will have advanced a lot.
