Its one and two star share is 2 points below the typical installer in Eugene. Across Oregon, 45 of the 106 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 41 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

Ordered by the share of one and two star reviews, weighted by how many reviews stand behind it. It ranks review records, not workmanship.

What reviewers said

  • 1★ · around August 2025 · the company replied

    Not an honorable company. Solar consultant Justin did not honor his appointment with me and then lied about it to place blame elsewhere. He would not even admit what he did. Very unprofessional work practices.

    As a new EV owner I was apprehensive about getting a home charger. I knew of AES' reputation in Solar Installation. I have worked with the owners of AES previously, and wanted to go with a local business I trusted. I will look into having them complete a battery storage system now that Oregon is reinvesting in EV systems. Thank you for getting me rolling in the EV world. Randy Rogers

    The knowledge and skills of the electricians were superlative along with the quality of their work.

    I sought bids from 4 solar companies before I selected Advanced Energy Systems for my solar project. This is the third solar project I have completed on a residence. I am impressed with the planning and equipment selected for the project. I am delight with the staff in their positive attitude, dedication to detail and completion of the project. I would give them a easy 5 star rating.

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 warranty and free estimate, but not in a sentence we can quote cleanly.

    Elsewhere

    • It is also reviewed on 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, 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.

    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.
