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

How does Rooftop 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 Rooftop 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.

Rooftop 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 Integrity6.8/10

Reviewers generally describe the sales process as clear and helpful, with several saying the proposal, explanation of options, and end-to-end handoff were smooth. A smaller set of complaints points to expectations not matching the outcome in a few cases, so this category reads positive overall but not spotless.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations. Reviewers frequently say the sales team explained the process well and took time to answer questions about system design, savings expectations, and project steps. Representative review excerpt: "Despite knowing he wouldn't be making money he still took time explaining why the building codes in addition too the shade created by the surrounding trees would make for an..."

Smooth proposal process. Many reviewers describe the quote and financing discussion as straightforward and say the broader going-solar process felt organized from the start. Representative review excerpt: "Rooftop Solar made every step of the “going-solar” process incredibly smooth…from the quote and financing to permits and installation."

Expectation mismatch in a few reviews. A small number of reviewers report frustration when the delivered experience did not match what had been described during the sale. Representative review excerpt: "Had good experience with installing the system, then rooftop installed a battery system back up for us, and sold us on we would have power when APS was down."

Price & financing transparency

Price Transparency6.8/10

Most reviewers who mention pricing or financing describe the costs as fair and the financing discussion as understandable. There is, however, a complaint about a high charge tied to panel removal and reinstallation, so the category lands in a mostly positive but somewhat mixed range.Solar.com's composite of published customer feedback, not a customer quote

Fair pricing mentioned. Several reviewers say the price felt fair and describe the financing and payment process as understandable. Representative review excerpt: "Personable people, professional, answered questions, done in one day, quality products, good price."

Helpful cost context. Some reviewers mention that the team answered financing questions and kept them updated on project progress, which helped make the budget side feel more transparent. Representative review excerpt: "Adam and Vanessa were there every step of the way to answer questions and keep us up to date on the progress of our project."

One cost complaint. One reviewer reports being surprised by the amount charged for removing and reinstalling panels during a roof replacement. Representative review excerpt: "$8600 for about 1/2 a day of labor (2-3 guys) to remove and then 1/2 day of labor to put panels back after the roof was replaced."

Communication & coordination

Communication7.0/10

Reviewers mostly describe the team as responsive, organized, and easy to reach during the project. A small number of complaints suggest communication did not work as well in every case, but the overall pattern is strongly favorable.Solar.com's composite of published customer feedback, not a customer quote

Responsive to questions. Reviewers repeatedly say staff members answered questions quickly and stayed available through the project. Representative review excerpt: "Rooftop Solar is responsive to questions and advice."

Organized handoffs. Several reviews describe the project coordination as streamlined, with clear updates from sales through installation and project management. Representative review excerpt: "Top notch customer service and their install process was as streamlined and organized as it could possibly be."

A few service complaints. A small number of reviewers report poor service or disappointing follow-through on their projects. Representative review excerpt: "Reading all the great reviews I’m even more frustrated by the abysmal service we’ve received with our large ground mount solar install out here north of Williams."

Timeline reliability

Timeline Reliability6.7/10

The timeline feedback is mostly positive, with many reviewers saying the process felt organized and that permitting or installation moved as expected. Still, a few reviews mention delays or waiting on third-party activation, so timing appears less consistent than the strongest service categories.Solar.com's composite of published customer feedback, not a customer quote

Process often felt timely. Reviewers often say the company kept the project moving and handled permitting and installation in a structured way. Representative review excerpt: "Top notch customer service and their install process was as streamlined and organized as it could possibly be."

Coordination around deadlines. Some reviewers say Rooftop gave them confidence about meeting a timing target tied to incentive timing or project deadlines. Representative review excerpt: "Rooftop Solar made every step of the “going-solar” process incredibly smooth…from the quote and financing to permits and installation."

Delays still show up. A few reviewers report waiting longer than expected for commissioning or describing the service as slower than hoped. Representative review excerpt: "Recently had our solar installed by Rooftop and even though we are STILL waiting for APS to come and commision the system, we could not be more thrilled with the..."

Workmanship & site care

Workmanship7.7/10

Workmanship is one of the strongest areas in the review set. Reviewers consistently describe the crews as professional and the installs as cleanly executed, with no complaint pattern showing up in the available evidence.Solar.com's composite of published customer feedback, not a customer quote

Professional crews. Reviewers repeatedly describe the installation teams as professional, organized, and respectful on site. Representative review excerpt: "Top notch customer service and their install process was as streamlined and organized as it could possibly be."

Clean installation work. Several reviews note that the install process went smoothly and that the finished work met expectations. Representative review excerpt: "Rooftop solar installed my system in Prescott Valley."

Positive team experience. Some reviewers specifically thank the crew for the installation and mention a professional relationship throughout the project. Representative review excerpt: "Solar Insure is greatfull for the professional relationship we have with Rooftop, offering solar and peace of mind to homeowners."

Long-term support & performance

Long-Term Support5.0/10

Post-install feedback is more mixed than the installation-phase reviews. Many reviewers say their systems are producing well and monitoring works, but one complaint about backup-power expectations pulls the category down and suggests service after turn-on is less consistent.Solar.com's composite of published customer feedback, not a customer quote

Systems often work well. Several reviewers say their systems have been performing smoothly after activation and that monitoring has been useful. Representative review excerpt: "The installation went flawlessly and the system has been working great since it was turned on thru APS in February 2026."

Positive day-to-day production. Reviewers also report steady operation and satisfactory ongoing savings once the system is running. Representative review excerpt: "It has worked flawlessly for me every day and saved me a ton of money off my APS bill."

Backup-power expectation issue. One reviewer says the backup setup did not meet the performance they say was described during the sale. Representative review excerpt: "Had good experience with installing the system, then rooftop installed a battery system back up for us, and sold us on we would have power when APS was down."

Bottom line: Rooftop Solar’s review profile is strongest on workmanship, communication, and the overall installation experience, while sales clarity and pricing are generally viewed positively. The weakest area is long-term support and performance, where most feedback is good but one complaint pattern suggests post-install follow-through is less consistent than the installation itself.

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.
