What reviewers said

  • 1★ · around July 2026

    I spent been over $100,000 for 2 PowerWalls, 2 SPAN Panels, a SolarEdge inverter, dozens of panels and a number of other things. I then call them up to see if they can hook up a Tesla Wall Connector and Tesla Gateway and they said it was too small of a job. I need a company that can not pick and choose jobs. At the same time they wanted to bid on my farm installation that was between $150K- $250K. I went with another provider.

    Be very careful using this company, they over promised a project and then had to shrink the size of the project making it not cost effective. They then refused to refund the down payment. Read their fine print and have a lawyer review your contract. We ultimately went with another company that was also cheaper. The communication with straight up solar is very lack luster as well. Doug wideman was who we dealt with. Avoid him.

    One of their trucks passed me going over 100 miles an hour, almost hit me too. If they are that disrespectful on the road, then I definitely don't want them working for me!

    Straight up solar did an excellent job of installation. We do wish that we had shipped a bit more and also would have liked to have had actual in person conversations with the sales persons. We have not had contact from the company since installation 3 years ago. Had one power outage including no power from the batteries and had no one in the company to contact for assistance

    Had an inverter go south four years in. Straight Up got me a new inverter, back up and running. Very good communication, fair prices, no problems.

    What an amazing company! They handled all our business solar needs in a professional and courteous manner. I highly recommend Straightup Solar.

    I had StraightUp Solar install solar panels back in 2019, providing about 20% of our electricity needs. The installation was done very well, and the energy generated has been roughly constant for all 7 years, and the electronic reporting has been excellent. Recently, I had the panels cleaned, though they were not that bad. The crew found a deteriorated connector and replaced all the connectors with new ones as part of the warranty from StraightUp Solar. We have been very happy to have the solar electricity! I only wish I had more space to put in more.

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

Elsewhere

  • It is also reviewed on the Better Business Bureau. 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.
