There are some satisfied customers that like their particular installation and it is good to hear first hand experience.
I’m in Phoenix valley and there are more scams, damaged roofs, and power company games going on than I want to be involved with. Concrete tile roofs with light weight felt underlayments are easy to damage and very high temp works against efficiency.
My son-in-law in Tampa is a techno-geek and a natural born deal maker. He put up a top of the line installation on their house as the daughter wanted it. He did not lease it. He paid for it all up front. He spent over 30k and says that now that it has been going for two years he sees an after depreciation break even at 15 years, but they are very smart with taxes as well.
He can afford it either way. He advised me that the heat of Phoenix, despite the lack of clouds, could greatly reduce effiency, output and service life of his top of the line panel if I were to try the same.
That is true. In fact in winter I have had my system shut down because the cold made the panels too efficient. Over voltage. 'Course it was down around zero. But after 30 minutes or so as the sun shifted the system would fire back up.
