Its one and two star share is 3 points below the typical installer in Wilmington. Across Delaware, 16 of the 18 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 9 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

Every company we hold in Wilmington, on one axis

Each mark is one company we hold in Wilmington whose Google breakdown has been read, placed by its share of one and two star reviews. Wise Power Systems, Inc. is the red one. The amber line is the middle of that set, which includes suppliers and maintenance businesses as well as installers.

    Great results and very cheap. This is exactly what I needed. I will be back for more very soon.

  • 5★ · around January 2026

    Efficient energy solutions and friendly staff. They helped us Install our Solar equipment quickly. The customer service team on the hotline is expert, and the phone number is always open for help.

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.

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.

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 found nothing on a website for this company that states a warranty, a licence or how long it has traded.
  • 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.
