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

How does Simmitri 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 Simmitri 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.

Simmitri 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 Integrity7.6/10

Reviewers generally describe the sales process as clear, informative, and low-pressure. Positive comments focus on thorough explanations, tailored recommendations, and proposals that matched expectations, while a smaller set of complaints mention pushy sales behavior or frustration around the proposal process.Solar.com's composite of published customer feedback, not a customer quote

Clear, low-pressure sales process. Reviewers say the sales approach was informative, polite, and focused on their needs rather than pressure. Several describe getting detailed answers and guidance that fit their situation.

Helpful proposal guidance. Reviewers report that questions were answered thoroughly and that the team walked them through the process from the start. Some also say the quoted cost was honored. Representative review excerpt: "They walked us through the entire process, diligently answered all of our questions (we had many :) and came in at quoted cost."

Sales pressure or expectation concerns. A smaller group of reviewers describe discomfort with the sales approach or felt expectations were not aligned during the proposal stage. These comments point to isolated but real friction around how the process was handled. Representative review excerpt: "If you are looking for just a salesperson they will take you."

Price & financing transparency

Price Transparency7.0/10

Reviewers mostly describe pricing and financing as straightforward, with several noting quoted pricing and fair estimates. The main complaints center on higher-than-expected bids, upfront payment issues, and a few reports of cost-related frustration tied to repairs or follow-up work.Solar.com's composite of published customer feedback, not a customer quote

Quoted pricing often matched expectations. Reviewers say the team explained costs clearly and, in several cases, came in at the quoted price. Some also describe the pricing as fair for the work performed. Representative review excerpt: "They walked us through the entire process, diligently answered all of our questions (we had many :) and came in at quoted cost."

Fair pricing on specific jobs. Some reviewers report receiving a fair price after discussing the issues they wanted addressed. These comments suggest the company can be transparent when scope is clear. Representative review excerpt: "He went over all the issues i had asked him to address and gave a fair price."

Cost concerns and payment friction. A smaller set of reviewers describe surprise around pricing or payment handling, including being asked to pay upfront or feeling the project cost was higher than expected. These complaints are not the majority, but they show that price expectations can matter. Representative review excerpt: "I paid my bill upfront in full."

Communication & coordination

Communication7.7/10

Reviewers frequently praise the team for staying in touch, answering questions, and helping coordinate a project with multiple steps and stakeholders. Complaints are less common, but when they appear they usually involve missed calls, lack of follow-up, or not being told about delays in time.Solar.com's composite of published customer feedback, not a customer quote

Responsive project communication. Reviewers say staff members were easy to work with and kept them informed throughout the project. Several mention timely answers and strong coordination across different roles. Representative review excerpt: "The staff is amazing to work with, especially the Project Manager Pamela Rodriguez and the Sales Manager Lonnie Cory."

Clear updates during the project. Some reviewers describe excellent communication and say they were walked through each step of the process. Others note that even complicated projects were handled with timely responses. Representative review excerpt: "We had a complicated project with a complicated team and every question was answered in a timely fashion."

Follow-up gaps for some customers. A smaller number of reviewers report missed calls, no-shows, or a lack of notice when schedules changed. These comments suggest communication is usually strong, but not uniform across every project. Representative review excerpt: "No one returned any of my phone calls."

Timeline reliability

Timeline Reliability7.3/10

Reviewers often say projects moved forward on a reasonable schedule, including permit, inspection, and utility steps. The main complaints involve delayed installs, missed appointments, or activation issues that pushed completion later than expected.Solar.com's composite of published customer feedback, not a customer quote

Projects completed on a workable schedule. Reviewers say the team kept the process moving and helped guide projects through permitting and utility approval. Some mention getting to completion in a timely manner. Representative review excerpt: "The people at Simmitri were very helpful in getting the solar system through the hoops to approval with PG&E."

End-to-end timing handled well. Several reviewers report that their projects finished on schedule or within a reasonable timeframe. These comments show that timing can go smoothly when the project is well coordinated. Representative review excerpt: "Within nearly 2 months everything was permitted, installed and running."

Delays and missed install dates. A smaller group of reviewers describe delayed appointments, no-shows, or commissioning delays tied to activation and inspection steps. These reports show that timeline reliability can slip on some jobs. Representative review excerpt: "once I had everything ready and they had scheduled an actual install date, no one had showed up (even though I sent emails and requested confirmation a week prior to..."

Workmanship & site care

Workmanship8.4/10

Reviewers overwhelmingly describe the installation crews as fast, competent, and professional, with many noting clean work and solid results. The complaints that do appear are mostly about cleanup, professionalism, or follow-up fixes rather than the core quality of the install itself.Solar.com's composite of published customer feedback, not a customer quote

Fast, clean installation crews. Reviewers frequently praise the crews for being fast, friendly, and clean on site. These comments suggest a strong day-of-install experience for many customers. Representative review excerpt: "The installation crew was fast, clean and friendly."

Thorough and competent work. Some reviewers say the installation team was competent and thorough, and that the project result met expectations. Others mention successful roofing or solar work tied to the install. Representative review excerpt: "The installation crew were fast, competent, and thorough."

Cleanup and professionalism concerns. A smaller set of reviewers report issues such as debris left behind or workers not appearing fully professional. These are isolated complaints, but they point to occasional lapses in site care. Representative review excerpt: "Lastly, the workers were not always professional--at one point, they left a pile of garbage on our roof, and it stayed there for over a week."

Long-term support & performance

Long-Term Support8.2/10

Reviewers generally describe good post-install support, smooth approval steps, and solid system performance after turn-on. A few complaints mention repair follow-through or escalation fatigue, but they are much less common than positive reports about output and ongoing help.Solar.com's composite of published customer feedback, not a customer quote

Strong post-install performance. Reviewers say their systems have produced well and that backup or solar output has met expectations. These comments suggest solid results after activation for many customers. Representative review excerpt: "Very happy with my battery backup and solar output."

Support after installation remained helpful. Some reviewers describe a seamless experience even after installation, including later additions and ongoing assistance. Others note that the system moved through approval and utility steps without major issues. Representative review excerpt: "We can say that installing and working with Simmitri was a seamless experience."

A few repair and follow-through complaints. A smaller number of reviewers report problems with repair completion or escalation before issues were resolved. These comments indicate that post-install support is usually positive, but not problem-free. Representative review excerpt: "Supposed to make some specific repairs where leaks were obvious and then do an entire roof inspection including replacing missing tiles."

Bottom line: SIMMITRI’s review profile is strongest on workmanship and long-term system results, with generally positive marks across sales, communication, and pricing transparency. The main watch-outs are occasional delays, missed follow-up, and a handful of cost or repair-related complaints, but those issues are less common than the praise overall.

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.
