#430 of 678 scored in California by Solar.com Installer Score

How does Wonder Electric compare where you live? Rankings are local; an installer that leads one city can trail in the next. See how they rank in your city →

Why this differs from star ratings: most five-star reviews say “great company” and stop, and star averages reward that. These category scores only count reviews with concrete evidence, weighted by recency and the reviewer’s track record. A company can hold a strong star average while specific categories score lower; that gap is usually where the real story is. Categories with more complaints than praise are the questions worth asking any bidder, not necessarily dealbreakers.

Where Wonder Electric builds

County-by-county activity from CPUC records through May 2026.

What this data covers: *Counts on this page, including the totals up top, come from investor-owned-utility interconnection records (SCE, SDG&E, PG&E). Work in municipal-utility territory, such as LADWP or city utilities, and outside California does not appear here, so this company's true totals are higher than shown. Unlike the county rankings, this profile also shows counties below the 250-install ranking floor.

Wonder Electric reviews: what customers say

An independent synthesis of published customer feedback, updated September 28, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity6.4/10

Reviewers give a mixed picture of sales and proposal integrity. The available evidence centers on complaints about pricing clarity and expectations, so this section reads more cautiously than the overall profile.Solar.com's composite of published customer feedback, not a customer quote

Overcharge concerns. Some reviewers describe feeling that pricing or proposal terms were not presented in a straightforward way and say they were prompted to compare bids more carefully. Representative review excerpt: "If you use this company for any work I'd get a few quotes first and do your own research so they can't excessively overcharge you like they tried to do..."

Limited evidence base. Only two substantive reviews informed this category, and both are complaints, so the score reflects concern around sales clarity rather than a broad pattern of praise.

Price & financing transparency

Price Transparency6.7/10

Feedback on pricing and financing is mostly positive, with several reviewers saying the final price felt fair or better than expected. There is still a smaller complaint pattern around pricing clarity and cost expectations, which keeps this category from reading as fully clean.Solar.com's composite of published customer feedback, not a customer quote

Reasonable final pricing. Several reviewers say the price was reasonable, that the team worked with them on cost, or that the final amount came in below what they expected. Representative review excerpt: "came out same day and worked with me on the price!"

Lower-than-expected cost. One reviewer reports that the work was completed correctly and that the final price was well under their expectation. Representative review excerpt: "Craig was here bright and early as scheduled, got the job done in a few hours correctly, and was way under what I was expecting to pay"

Pricing clarity concern. A smaller number of reviewers describe concerns about how the job was priced and say they wanted more clarity on what materials and labor should cost. Representative review excerpt: "What they didn't know is that I already had the job priced by a professional electrician who explained what needed to be done and what the materials would cost and..."

Communication & coordination

Communication7.0/10

Communication and coordination trend positive overall, with many reviewers describing timely callbacks, appointment updates, and smooth handoffs. The main complaints involve missed estimates or delayed follow-up, but those appear alongside a larger set of praise for responsiveness.Solar.com's composite of published customer feedback, not a customer quote

Fast callbacks and updates. Reviewers frequently say the team responded quickly, kept them informed about arrival timing, and handled scheduling or emergency calls promptly. Representative review excerpt: "We had a emergency late Sunday and managed to get John Masterson to call us back in less then 5min."

On-site responsiveness. Several reviews describe technicians arriving shortly after being called and being ready to help when they did. Representative review excerpt: "Not only did an electrician come out shortly after I called, Garrett came ready to help!"

Estimate follow-through concerns. A smaller set of reviewers says promised estimates did not arrive on time or at all after repeated follow-up calls. Representative review excerpt: "I followed up by phone a total of four times after that date, about a month apart each phone call, and still never got the estimate."

Timeline reliability

Timeline Reliability7.0/10

Timeline feedback is positive in the limited evidence available. Reviewers describe reliable arrival timing and consistent communication about when crews would show up, with no substantive complaint pattern in the sourced reviews.Solar.com's composite of published customer feedback, not a customer quote

Arrived as scheduled. One reviewer says the crew showed up when expected and completed the job efficiently. Representative review excerpt: "I’ve worked with electrical contractors all over the US and Wonder Electric is one of the highest quality companies I’ve had the pleasure of working with."

Clear arrival windows. Another reviewer highlights being told when the team was coming and how far away they were, which helped the appointment feel organized. Representative review excerpt: "I love the fact that they tell me when they’re coming and how far away they are they’re coming back to install some ceiling fans."

Workmanship & site care

Workmanship7.4/10

Workmanship and site care are described positively in most reviews, with praise for professionalism, technical knowledge, and follow-up fixes. There are a couple of complaints about installation quality and professionalism, but they are outweighed by stronger feedback on job quality and on-site conduct.Solar.com's composite of published customer feedback, not a customer quote

Professional crews. Many reviewers describe technicians as polite, knowledgeable, and on time during appointments. Representative review excerpt: "Our technician was polite, knowledgeable, and on time during both appointments this week."

Problem fixed and explained. Reviewers also say issues were resolved cleanly, with technicians walking them through the work before leaving. Representative review excerpt: "Our issue was fixed, he walked us through what he did, properly educating us and confirmed there was nothing else he could do before he left."

Installation mistakes reported. A smaller number of reviews describe installation work that was done incorrectly or with disappointing professionalism. Representative review excerpt: "I had issues with a recently installed mini split, that was installed incorrectly by mini split installers."

Long-term support & performance

Long-Term Support7.0/10

Post-install support and system performance are described positively in the available reviews. Reviewers mention troubleshooting, repairs, and familiarity with older systems, and there is no substantive complaint pattern in this category from the sourced evidence.Solar.com's composite of published customer feedback, not a customer quote

Troubleshooting and repair. One reviewer says the technician listened to concerns, troubleshot the issue, and repaired the problem successfully. Representative review excerpt: "listened to all my concerns, then he did some troubleshooting and was easily able to find and repair the problem."

Older-system expertise. Another review says the technician was familiar with older solar power systems and was able to diagnose errors effectively. Representative review excerpt: "Familiar with older solar power systems like Outback and able to effectively troubleshoot errors."

Serious electrical issue resolved. A third review describes a dangerous electrical problem being fixed after the crew came in and addressed it. Representative review excerpt: "We had a very bad electrical problem between two houses and through that we were getting shocked by our appliances, they came in, fixed it and did a little bit..."

Bottom line: Wonder Electric’s review profile is generally positive, with especially strong marks for workmanship, communication, and post-install support. The main caution points are around sales/proposal clarity and a smaller set of pricing or estimate-related complaints, while timeline feedback is positive in the limited evidence available.

Important context: this chart shows investor-owned-utility records only. Companies that shift work toward municipal-utility territory (LADWP and city power departments) or other states will show declining bars here even while building steadily elsewhere, and 2025-26 records also lag real installation dates. Treat this as a partial window, not the company's full trajectory.

How we built this data

Methodology: Counts are residential PV interconnections in investor-owned-utility territory (PG&E, SCE, SDG&E) per CPUC Rule 21 public records through May 2026. Postal and name variants are merged. Municipal utility territory such as LADWP, Glendale, Pasadena, Burbank, Anaheim, and Riverside Public Utilities is not included in those CPUC counts. Counts show recorded installations, not quality ratings. Reported costs are self-reported on owned-system interconnections. No installer can pay for placement.

Who we are: Solar.com is a solar marketplace — we connect homeowners with installers and earn a fee when projects move forward. These rankings and scores are computed from public installation records and published customer reviews. No installer can pay for placement, and no installer — including those we work with — can pay to change a score.
