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

How does Solarsesame 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 Solarsesame 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.

Solarsesame 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 Integrity7.7/10

Reviewers most often describe the sales and proposal process as clear, responsive, and tailored to their homes. A smaller set of reviewers report disappointment with promised savings, contract expectations, or the completeness of the initial system design.Solar.com's composite of published customer feedback, not a customer quote

Clear, customized consultations. Many reviewers say the quote and design process felt personalized and easy to follow, with staff explaining options and staying available for questions. Representative review excerpt: "I had an excellent experience with Kerrie from SolarSesame when she came to my home to provide a quote for a custom solar setup designed specifically to work with my..."

Good handoff from sales to installation. Reviewers also describe smooth coordination between the sales team and project staff, with details carried through from proposal to install. Representative review excerpt: "Coordinating of details from sales to installation was very good flow back-and-forth from Mei, our project coordinator."

Expectation-setting concerns. A minority of reviewers report gaps between what was promised and what they say they received, including concerns about system sizing, bill-reduction expectations, and timing commitments. Representative review excerpt: "Not only did he sell me a wholly inadequate system that does not meet the needs of our home and EV but he promised me 3 months of free payments..."

Price & financing transparency

Price Transparency5.8/10

Feedback on pricing and financing is mixed.Solar.com's composite of published customer feedback, not a customer quote

Strong value for some customers. Reviewers describe a recurring pattern in this area. Representative review excerpt: "Friendly, professional crew, great value with no upfront investment on my end, a competitive kilowatt price which slashed my $800/month energy bill to quarter."

Consultative pricing conversations. Some reviewers say the proposal discussion felt like a real consultation and that the final pricing matched their goals and roof needs. Representative review excerpt: "I sat down with Andrey to talk about Solar options for my home, and it felt like a real consultation, not just a sales pitch - I walked away with..."

Billing and reimbursement complaints. Other reviewers report surprise billing, delayed reimbursements, or confusion around how certain payments and incentive timing were handled. Representative review excerpt: "They even suggested that I go to MID myself to make the payment and promised they would reimburse me afterward."

Communication & coordination

Communication7.2/10

Most reviewers describe the team as responsive and organized, especially when a named coordinator stayed engaged through the process. Still, some reviewers report missed callbacks, inconsistent follow-up, or communication breakdowns when issues came up.Solar.com's composite of published customer feedback, not a customer quote

Responsive project coordination. Reviewers commonly say a coordinator or point person kept them informed and made the process feel organized. Representative review excerpt: "Coordinating of details from sales to installation was very good flow back-and-forth from Mei, our project coordinator."

Helpful explanations. Some reviewers note that staff explained the process clearly and answered questions in a way that reduced confusion during the project. Representative review excerpt: "I don't remember if Solar Sesame cold called me or I called them, but I do remember that Marcel did a great job of explaining the process."

Follow-up problems for a minority. A smaller group reports difficulty getting callbacks or consistent updates, saying they had to keep following up to get answers. Representative review excerpt: "So many times, they say they'll get back to me but it's just me following up with them bc they don't call back when they say they will."

Timeline reliability

Timeline Reliability6.7/10

Timeline feedback is positive overall but not fully consistent. Many reviewers say the project moved quickly and finished on schedule, while others describe delays tied to permits, inspections, no-shows, or utility activation.Solar.com's composite of published customer feedback, not a customer quote

Fast project movement. Several reviewers say the process moved quickly from quote to installation and, in some cases, to interconnection or PTO. Representative review excerpt: "The entire process moved at an incredible speed: July 23: Reached out for an initial quote July 24: Site inspection and design completed, and contract signed the exact same day..."

End-to-end scheduling support. Reviewers also describe the company handling permits, inspections, and interconnection as part of the project flow. Representative review excerpt: "They covered everything end to end, including permits, inspections, everything."

Delays and missed appointments. Other reviewers report permit delays, no-shows, or frustration when inspections and utility-related steps took longer than expected. Representative review excerpt: "Ie: they no-show They were scheduled to come between 8-830am in anticipation of a city inspection."

Workmanship & site care

Workmanship7.4/10

Most reviewers describe the installation crews as professional, respectful, and efficient, with many saying the finished work looked clean. The complaint pattern centers on code-related fixes, inspection rework, and a smaller number of site-care concerns.Solar.com's composite of published customer feedback, not a customer quote

Professional, respectful crews. Reviewers often say the installers were courteous, efficient, and respectful of the property during the work. Representative review excerpt: "The crew that did the installation was very respectful and efficient to us & our property."

Clean and complete installations. Several reviewers report that the panels, battery components, and related equipment were installed well and left in good condition. Representative review excerpt: "Solar panels all installed well and powerwall functioning."

Inspection-related rework. Some reviewers describe installations that later needed fixes after inspection issues or placement concerns, and a few mention cosmetic damage or site-care complaints. Representative review excerpt: "This resulted in the equipment being installed in a location that was not to code, which resulted in a failed inspection and additional work and cosmetic damage to the exterior..."

Long-term support & performance

Long-Term Support6.8/10

Post-install feedback is generally favorable, with many reviewers saying systems came online and monitoring or support worked as expected. At the same time, some reviewers report service frustrations, unresolved warranty questions, or issues tied to production, repairs, or incentive timing after turn-on.Solar.com's composite of published customer feedback, not a customer quote

Systems working after activation. Many reviewers say the system eventually operated as expected, with app monitoring or post-turn-on performance meeting their needs. Representative review excerpt: "First I was a skeptic, this is too good to be true, but eventually it all came thru and now I'm just watching the status in the Tesla solar app..."

Responsive help on some issues. Some reviewers note that the company responded quickly when a problem came up after installation or during equipment coordination. Representative review excerpt: "Alarming that the system had an issue when it's so new but at least they responded quickly to that one issue."

Post-install service frustrations. A smaller group reports dissatisfaction with follow-up, including delays in resolving issues, disputes over promised incentives, or concerns about accountability after the system was live. Representative review excerpt: "I was caught in a frustrating cycle of communication with Sun Power, and despite my panels now working, Sesame has refused to honor the incentive that was promised."

Bottom line: SolarSesame’s review profile is strongest in sales clarity, communication, workmanship, and overall project coordination, with many reviewers describing a responsive and organized process. The main softer spots are price and financing transparency, plus occasional complaints about timeline slippage and post-install follow-up, especially around delays, billing, and incentive timing.

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.
