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

How does Mid-State 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 Mid-State 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.

Mid-State Solar reviews: what customers say

An independent synthesis of published customer feedback across Google and Yelp, updated September 23, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity7.4/10

Reviewers most often describe the sales and proposal process as clear and straightforward, with multiple comments pointing to helpful quotes and reasonable expectations. The category does not show a complaint pattern in the available evidence, so the overall read is positive with a modest amount of caution only because the score sits just below 7.Solar.com's composite of published customer feedback, not a customer quote

Clear quoting. Reviewers say they received quotes that were easy to understand and that the team was helpful in setting expectations for the job. Representative review excerpt: "I called Mary and she gave me a quote for a new system."

Local, in-home assessment. Customers also describe value in the company coming out to the home and reviewing the site before proposing work, which suggests a more tailored sales process. Representative review excerpt: "I realized then that it was a huge difference to have a local company, that came to the house to see what they had to work with and who know..."

Repeat-project confidence. Some reviewers mention having multiple projects completed over time, which reads as a sign that the proposal process held up across different jobs. Representative review excerpt: "We have had solar electric panels put on two houses and pool heating on one."

Price & financing transparency

Price Transparency6.8/10

There is one complaint about a repair estimate not being provided, so the category is positive overall but not without a transparency concern.Solar.com's composite of published customer feedback, not a customer quote

Reasonable pricing. Several reviewers say the pricing felt fair and that the company stood behind its work. Representative review excerpt: "The prices are reasonable and they stand behind their work."

Pricing cost. Reviewers describe a recurring pattern in this area. Representative review excerpt: "They beat the competition by thousands of dollars and the response for service is incredible."

Estimate gap on repair work. One reviewer reports difficulty getting a repair quote, which points to a transparency issue for service-related pricing in at least one case. Representative review excerpt: "But he could not give us a quote on the cost of the repair."

Communication & coordination

Communication7.4/10

This category is mostly positive, with many reviewers describing fast responses and helpful follow-up even after installation. At the same time, the complaint pattern is real: some customers report missed callbacks, delayed quotes, or a lack of proactive updates when schedules changed.Solar.com's composite of published customer feedback, not a customer quote

Strong follow-up. Reviewers frequently say the team stayed responsive after the job was finished and answered questions quickly. Representative review excerpt: "Their follow-up after installation is phenomenal and after 3 years, they still respond to any questions I have with great speed."

Helpful issue resolution. Customers also report that the company was eager to help resolve problems and address follow-up requests. Representative review excerpt: "They responded very quickly and were eager to help me resolve my problems."

Missed callbacks. A smaller but meaningful set of reviews says service requests and quote follow-through were not handled promptly, including cases where customers felt left waiting for contact. Representative review excerpt: "Sent in service request, never received an email, call or text from company."

Timeline reliability

Timeline Reliability7.1/10

Reviewers often describe the company as efficient on scheduling and permitting, with several mentions of the team coordinating smoothly with city or related trades. There is also at least one complaint about a missed delay notice, so the timeline picture is generally positive but not perfect.Solar.com's composite of published customer feedback, not a customer quote

Permits handled smoothly. Customers say the crew worked through permits and inspections without creating problems for the homeowner. Representative review excerpt: "He and his crew did the installation seamlessly, working with the city on permits and inspections so that we had no difficulties."

Quick scheduling. Some reviewers note that jobs were scheduled promptly and that the company coordinated around other work when needed. Representative review excerpt: "The pool solar is new (and already working great!) but they were quick to get me in the schedule, and worked with the guy who had to do some cement..."

Delay communication issue. One review describes a situation where a delay was not proactively communicated, which suggests occasional gaps in schedule updates. Representative review excerpt: "I told her everyone including the technician is very busy; however, everyone carries a cell phone and a simple call to let me know there was a delay would have..."

Workmanship & site care

Workmanship7.8/10

Workmanship reviews are strongly positive overall, with many customers describing smooth installs, professional crews, and solid cleanup or coordination around the site. Complaints are rare but do appear, mainly in the form of a customer disputing responsibility for a leak after installation.Solar.com's composite of published customer feedback, not a customer quote

Smooth installation. Reviewers commonly describe the install process as efficient and well executed, with crews handling the work cleanly and professionally. Representative review excerpt: "He and his crew did the installation seamlessly, working with the city on permits and inspections so that we had no difficulties."

Durable results. Some customers point to long-lasting systems and successful follow-up work as evidence of solid installation quality. Representative review excerpt: "Mid-State Solar put in our pool solar system in 2003 and this is the first time I have had to call them for a small leak/repair (2026!!) Quality system."

Site-related dispute. One review raises a concern about a leak and says the issue was not treated as installation-related, which reads as a workmanship-related complaint rather than a broad pattern. Representative review excerpt: "As to fixing a leak that wasn't there when they touched our pool equipment, we were told that it wasn't caused their install to call our pool company."

Long-term support & performance

Long-Term Support7.8/10

Most reviewers describe systems producing well and the company continuing to respond after installation, including in follow-up service situations. The complaint pattern is limited, but there are a couple of reports about service-request responsiveness, so the post-install experience looks good overall with some occasional gaps.Solar.com's composite of published customer feedback, not a customer quote

Good system output. Reviewers say their systems have performed well over time, including comments about strong production and effective upgrades. Representative review excerpt: "Mid-State Solar installed a 15k solar/battery system for us about 3 years ago."

Responsive long-term service. Customers also report that the company continued to answer questions and handle issues long after the original job was complete. Representative review excerpt: "Mid-State Solar put in our pool solar system in 2003 and this is the first time I have had to call them for a small leak/repair (2026!!) Quality system."

Service-request gap. One reviewer says a service request did not receive a response, which suggests the post-install support experience can be inconsistent in some cases. Representative review excerpt: "Sent in service request, never received an email, call or text from company."

Bottom line: Across 49 substantive reviews, Mid-State Solar scores 8.2/10 on Solar.com, with especially strong marks for workmanship, system performance, and generally clear sales communication. The main watch-outs are inconsistent responsiveness, a few timeline-update complaints, and occasional pricing or quote follow-through issues.

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.
