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

How does Sunfusion 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 Sunfusion 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.

Sunfusion Solar reviews: what customers say

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

Sales & proposal integrity

Sales Integrity5.6/10

Reviews on sales and proposal integrity are mixed, with a fairly even split between praise and complaints. Positive reviewers describe clear explanations, honest guidance, and outcomes that matched expectations, while negative reviewers report promises that did not line up with the final system or contract terms.Solar.com's composite of published customer feedback, not a customer quote

Clear guidance for some customers. Some reviewers say the sales process was educational and helped them understand whether solar made sense for their usage. They describe staff as honest, polite, and available when questions came up. Representative review excerpt: "Not only did he educate me, but he showed me that, based on my usage, it would be economical to purchase solar panels (and go with Net Metering) and even..."

Promises not reflected in delivery. Other reviewers report being promised outcomes such as grid independence or very low bills that did not materialize. A few also say contract details or system specifications were not honored as understood. Representative review excerpt: "We are also not grid independent as we were promised.We were told our electric bill would be about $10 a month."

Price & financing transparency

Price Transparency5.3/10

At the same time, reviewers report surprise issues around contract scope, rebate timing, deposits or financing expectations, and final equipment or bill outcomes not matching what they say was discussed.Solar.com's composite of published customer feedback, not a customer quote

Contract and rebate concerns. Other reviewers report disputes about what was included, mismatches between the installed system and submitted paperwork, and issues tied to rebate timing or reimbursement. Some also say financing or lease expectations did not match the final arrangement. Representative review excerpt: "This caused significant issues when dealing with the state rebate program, and we almost did not receive our reimbursement because the equipment installed did not match what had been submitted..."

Pricing pricing for some projects. A few also note that the company worked through scheduling and activation without extra pricing surprises from their perspective. Representative review excerpt: "I shopped around about 15 different solar company's and picked SunFusion seems like they were selling what I needed at a very competitive price."

Communication & coordination

Communication4.1/10

Communication is one of the weakest areas in the review set. A smaller group of customers describes prompt answers and helpful coordination, but many more say calls were not returned, updates were sparse, and getting follow-up required repeated outreach.Solar.com's composite of published customer feedback, not a customer quote

Hard to reach after problems arose. Many reviewers say they could not get return calls or consistent updates once an issue came up. They describe repeated voicemails, missed follow-up, or having to keep pushing for any response. Representative review excerpt: "When they didn't respond I tried calling several times but only got VM."

Responsive in some cases. Some reviewers say the team answered questions promptly and stayed helpful through the process. A few also describe direct communication that made coordination feel manageable. Representative review excerpt: "If you are looking to do business with a company that answers the phone promptly and answers all your questions thoroughly….I highly recommend Sunfusion."

Timeline reliability

Timeline Reliability6.4/10

Timeline reliability trends slightly positive overall, with several reviewers saying installation and activation stayed on schedule. Still, some customers report delays tied to troubleshooting, permit-related steps, or multiple trips back to finish the job.Solar.com's composite of published customer feedback, not a customer quote

On-time completion for some jobs. Several reviewers say the project finished when expected and that the panels were turned on after inspections without unnecessary delay. Others describe the installation as quick, efficient, and smooth. Representative review excerpt: "They finished exactly when they said they would and even worked with us to get the panels turned on once all the inspections were done as I was out of..."

Delays and repeated visits. Some reviewers describe delays, back-and-forth visits, or troubleshooting that extended the process. In those accounts, timing issues were tied to install corrections, testing, or other follow-up work. Representative review excerpt: "It was cloudy and rainy and they had to make several trips back and forth throughout the install to test and work through leaks and calibration."

Workmanship & site care

Workmanship4.5/10

Workmanship and site care lean negative overall. Positive reviewers describe professional crews, efficient installations, and good coordination with related trades, but a substantial group reports installation mistakes, wiring or configuration problems, and concerns about repairs or cleanup.Solar.com's composite of published customer feedback, not a customer quote

Installation mistakes and follow-up fixes. Other reviewers report wiring, configuration, or equipment problems that required correction after the install. These comments also include concerns about system setup and the need for additional repair work. Representative review excerpt: "I now know that the shutoff switch they installed does not allow me to by pass the battery and connect to the grid as expected."

Professional crews on some installs. Some reviewers say the crew was professional, efficient, and careful in coordinating the solar layout with other work on the property. A few also mention helpful handoff at the end of the installation. Representative review excerpt: "He, his wife, Sandy and his fantastic crew are professionals in every way."

Long-term support & performance

Long-Term Support5.0/10

Post-install support and system performance are mixed to negative. Some reviewers report that the system works well and that support has been helpful, but a larger set says they encountered performance issues, technical problems, or difficulty getting warranty or service help after the system was turned on.Solar.com's composite of published customer feedback, not a customer quote

Performance and service problems reported. Other reviewers say they experienced system issues, inverter or battery problems, or configuration concerns after installation. Some also report trouble getting service help when they needed it. Representative review excerpt: "My family bought a solar battery through this company and it is having issues."

Helpful support for some owners. A number of reviewers say the system has performed well and that technical support helped them better understand or improve it after installation. These accounts describe ongoing care and useful follow-through. Representative review excerpt: "They have helped us better understand our system, make improvements and show genuine care for their products' success."

Bottom line: SUNFUSION SOLAR’s review profile is mixed, with stronger marks for timeline reliability than for communication, workmanship, or post-install support.

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.
