Its one and two star share is level with the typical installer in the Glendale area. Across California, 788 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 42 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

What reviewers said

  • 5★ · around August 2026

    From beginning to end the people at Altadena Solar were great. They were great in the initial interactions over e-mail about what my options might be, and then in the several in-person interactions to help scope out what would work best for my needs, and then chasing down the needed permits, and finally with the installation. Everyone I interacted with at the company knew what they were doing and was pleasant to interact with. If you want a great solar installation at a good price, go with Altadena Solar! For the last 2-month period, my electricity usage part of my electric bill was zero! Stil

    It's important to support local businesses, especially Altadena businesses. In this case, we contacted Hans and Joy with Altadena Solar re a consultation for a PV system w/battery backup. While not the least expensive option, we found the proposal to be thoughtful and thorough. Installation took two days, and was peerless. Now that it's been operating for 3 months, we are delighted with the performance. We also received newer model panels than were spec'd at no extra cost to the project. Highly recommended.

    We are completely satisfied with the Altadena Energy and Solar company! The quality of work is exceptional and the installation of the system was done in 2 days! Highly recommended!

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

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 financing, free estimate and licence number, but not in a sentence we can quote cleanly.

    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 Instagram, LinkedIn, X and Facebook. A page that stopped posting years ago tells you something a listing will not.

    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

    • 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.
