Its one and two star share is level with the typical installer in Illinois. Across Illinois, 96 of the 183 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 117 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

What reviewers said

  • 1★ · around August 2024 · the company replied

    I did not appreciate the door to door soliciting. When speaking with the sales representative they were only concerned with gathering our comEd monthly bill. They did not have any information beyond the few laminated sales sheets. Due to the lack of transparency and sales information, I am giving Semper Solr 1 star.

    Thanks, everything's fine. We're happy with everything.

    The installation was quick easy. The workers were polite and friendly. The system is working perfectly

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

    Elsewhere

    • It posts on 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.
