There you go: Costco has great stuff. Costco solar is a pretty good recommendation. As long as you are getting UL approved solar panels and equipment, it pretty much all comes with a 25 year warranty. Get it done before the end of the year and you get a 30% tax rebate from the IRS. Hard to beat that.

It may need some lead time because a roof mount suggests you redo your roof as you put on the panel mounts. It's best to coordinate both to get the best installation.
