Joe the fundamental difference in our perspectives here is you place greater value in claims of useful life than i do. i believe the appropriate response to these claims is turbo's. the claim is as strong as the company and with so many new co's...well it's hard to figure; hence my recommendation to discount claimed useful life.

I have NEVER claimed to be an expert on solar panels, am simply sharing my views. I am most certainly an expert on working through cost/benefit analysis however and in such things i suggest you'll find my logic to be useful.

I am somewhat involved in this game as i volunteer on my towns utility commission (we own our electric utility) and while my participation tends towards the numbers side of things i am nevertheless exposed to a reasonable amount of industry 'noise'.
