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

How does Fusion Solar 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 Fusion Solar 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.

Fusion Solar 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 Integrity7.0/10

Reviewers most often describe the sales process as professional, knowledgeable, and clear about system design and expected savings. A smaller set of reviewers reports concerns about sales behavior and information handling, so the section reads positive overall but not spotless.Solar.com's composite of published customer feedback, not a customer quote

Representative review excerpt: "The salespeople were rude to both my wife and I, the main salesperson had the attitude that he really didn't want to be there when meeting with my wife and..."

Price & financing transparency

Price Transparency6.8/10

The available reviews are favorable on pricing and financing transparency, with customers saying they were given options and did not encounter surprise costs. The evidence base is small, so this category should be read as positive but limited.Solar.com's composite of published customer feedback, not a customer quote

Clear options. Reviewers say the company presented options and completed the work at a fair price. Representative review excerpt: "Gave me my options and completed the job for a fair price."

Loan and savings context. One reviewer describes the financing in practical terms, noting expected loan paydown alongside utility-bill savings. Representative review excerpt: "With that money we will pay down our loan and continue to save on our utility bill."

Communication & coordination

Communication7.1/10

Reviewers consistently describe strong communication and straightforward coordination from the first meeting through office follow-up. The available feedback in this category is uniformly positive in the corpus.Solar.com's composite of published customer feedback, not a customer quote

Timeline reliability

Timeline Reliability7.0/10

Reviewers generally report that projects moved on schedule, with crews completing installations when promised. The available feedback is entirely positive, though it is based on a relatively small number of reviews.Solar.com's composite of published customer feedback, not a customer quote

On-time install work. Reviewers say the crew completed the project within the promised time frame. Representative review excerpt: "The day the crew came to install they were very quick and professional, and completed our project in the amount of time they promised."

Overall positive timing. Reviewers also characterize the overall schedule experience as positive from install through completion. Representative review excerpt: "I recently had solar panels installed by Fusion Solar and overall, my experience was positive."

Workmanship & site care

Workmanship7.4/10

Reviewers describe the installation crews as professional, quick, and careful with the design and execution of the system. No site-care complaints show up in the available corpus, so this category reads as strongly positive based on the reviews analyzed.Solar.com's composite of published customer feedback, not a customer quote

Professional installation. Reviewers say the crew was quick and professional during installation and finished as promised. Representative review excerpt: "The day the crew came to install they were very quick and professional, and completed our project in the amount of time they promised."

Long-term support & performance

Long-Term Support7.4/10

There is limited post-install feedback, but the available reviews indicate the system is producing as expected and lowering the electric bill. With only one evidence review in this category, the picture is encouraging but thinly sourced.Solar.com's composite of published customer feedback, not a customer quote

Production results. A reviewer says the system is producing daily energy and helping lower the utility bill. Representative review excerpt: "We are excited to see our daily solar production lowering our PG&E bill."

Ongoing savings context. The post-install feedback points to expected performance after activation, with savings described in terms of a lower utility bill. Representative review excerpt: "We are excited to see our daily solar production lowering our PG&E bill."

Bottom line: Across the 20 substantive reviews analyzed, FUSION SOLAR is described most often in positive terms, especially for communication, installation quality, and timeline reliability. The main recurring caution in the corpus is a small number of complaints about sales conduct and information handling, while pricing and post-install support have limited but favorable feedback.

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.
