Its one and two star share is 32 points above the typical installer in California. Across California, 106 of the 1,529 installers whose breakdown Google has published carry a higher share than this one.

The percentages are Google’s own arithmetic over every review it holds, not a sample we assembled. Separately we hold 3 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

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.

    Its website also mentions warranty, but not in a sentence we can quote cleanly.

    As Google published them when we last read the listing, not a live check. Ring before you drive anywhere.

    Who Google shows alongside them

    Google’s own “people also viewed” set, in Google’s order. It is Google’s comparison, not ours.

    The ones without a link have no page here, either because Google does not categorise them as solar businesses or because we could not match the name to a listing with confidence.

    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

    • We hold no review text for this company, so there is nothing to quote.
    • 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.
    • 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.
