    Green Stock Solar is Napa’s best residential solar power installer. Committed to the highest installation quality, local customer service and industry best technology, Green Stock has earned their reputation the right way. Here is a picture of the SunPower panels they use, the most powerful in the industry.

Reviewer names are not published here. Negative reviews are shown first because they are the ones a listing hides, not because they are more representative.

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

  • Free estimate

    “usage or electricity bill for a free estimate and financial analysis, including the…”

Elsewhere

  • It is also reviewed on the Better Business Bureau and Yelp. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.
  • It posts on X, Instagram and Facebook. A page that stopped posting years ago tells you something a listing will not.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

What we don't know

  • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
  • Google publishes no street address for this company, so we cannot say which town it is based in. Napa is the area its listing was returned for, not an address we hold.
  • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
  • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
