Its one and two star share is 3 points below the typical installer in Riverside. 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 11 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

    Boss. Can I add you on WhatsApp so we can discuss this?

  • 5★ · around August 2022 · the company replied

    If you're looking for the right company to provide your home with solar, these guys are it! You can't imagine what a headache it was getting quotes and trying to find the best contractor and system. I must have gone through five different companies before I came across Optimum Solar Power - I just wish I found them sooner. They were able to answer all my questions, show me how the system would work on my home and most importantly, save me money in the long run. They're extremely professional and have an amazing crew. The design, engineering and equipment were all top notch. I'm extremely happy

    Alot of really hard workers who answer and are available when most companies are not.

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.

  • Warranty

    “our products come with an extended warranty of around 20 years. UNBEATABLE PRICES…”

Its website also mentions free estimate and 24/7 availability, 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.

Something wrong here? Tell us and a person will read it.
