Sales & proposal integrity
Sales Integrity7.1/10
Reviewers mostly describe clear, straightforward sales conversations and proposals that matched what was discussed. A small number of complaints raise concerns about disclosure and follow-through, but the overall pattern is positive.Solar.com's composite of published customer feedback, not a customer quote
Clear, no-pressure sales process. Several reviewers say the initial sales experience felt low-pressure and easy to understand, with estimates delivered without a drawn-out pitch. They describe the proposal stage as efficient and helpful for setting expectations. Representative review excerpt: "Was very against the salesy solar people I had met previously - then we met Matt and his team..."
Forecasts lined up with results. Some reviewers report that the projected savings matched what they later saw after the system was running. That suggests the proposal details were, in many cases, reasonably aligned with the finished project. Representative review excerpt: "Now that the panels are in operation, the savings that were forecast are right on the estimates!"
Disclosure and follow-through concerns. A small number of reviewers describe concerns tied to what was disclosed up front and whether later project obligations were completed as expected. These comments point to occasional breakdowns in contract expectations and completion details. Representative review excerpt: "He "ghosted" us after panel and battery install, didn't finish the final project requirements necessary for passing city inspection, never filed the necessary application with SDGE (which should have been..."
Price & financing transparency
Price Transparency6.7/10
Feedback on pricing and financing leans positive, with some reviewers saying the final cost matched what was promised. Still, a few complaints mention disclosure and surprise-related concerns, so this area reads as mixed rather than uniformly strong.Solar.com's composite of published customer feedback, not a customer quote
Cost matched the quote. Some reviewers say they checked the bottom-line cost over time and found it matched the original promise. That supports a positive read on pricing transparency for those projects. Representative review excerpt: "I waited one year to write this review because I wanted to verify that the bottom line cost to us was what was promised."
Value and savings viewed favorably. A number of reviewers describe getting a deal they felt was strong for the system delivered, and some say the forecast savings tracked closely with results. Those comments suggest pricing was understandable and acceptable for many customers. Representative review excerpt: "Even my brother, who works in the solar business, could not believe the deal I was getting for such a great system."
A few disclosure-related complaints. A small set of reviews raise concerns about undisclosed details or unexpected issues tied to the project and its completion. These complaints keep the category from reading fully positive. Representative review excerpt: "He did not disclose this at anytime, albeit the CSLB states "The licensee is not entitled to operate during the period of suspension until certain requirements are met." On checking..."
Communication & coordination
Communication6.8/10
Many reviewers describe responsive communication, friendly coordination, and helpful follow-up during the project. At the same time, a noticeable set of complaints points to unreturned calls, limited updates, and difficulty getting projects closed out.Solar.com's composite of published customer feedback, not a customer quote
Responsive and available. Several reviewers say the owner and crew were easy to reach, answered questions, and stayed helpful through bidding and installation. Those experiences suggest solid day-to-day coordination for many projects. Representative review excerpt: "The crew was very friendly and punctual and the owner Matt was available and answered all of my questions."
Good handoffs and follow-up. Some reviewers describe smooth communication from the estimate stage through follow-up questions, with results that matched expectations. That indicates a generally workable project management process when things stayed on track. Representative review excerpt: "I give Simms Solar my highest recommendation as they were great during the bidding, installing, follow up questions, and the results were as promised."
Communication lapses on some jobs. Other reviewers report difficulty getting responses, including repeated calls and texts without resolution and projects that felt abandoned before completion. These complaints suggest communication can break down when there are schedule or closeout issues. Representative review excerpt: "Matt has not responded to any of my calls or texts to get this done after saying all along that "we're good to go"."
Timeline reliability
Timeline Reliability6.1/10
Timeline feedback is mixed, with some reviewers saying work stayed on schedule and others describing long delays before activation or completion. Permitting, inspection, and utility-related steps appear to be a recurring pain point in the negative reviews.Solar.com's composite of published customer feedback, not a customer quote
On-schedule projects. Some reviewers say their projects were completed on the timeline originally promised. These comments suggest the company can keep to schedule on at least some jobs. Representative review excerpt: "Both projects were done on time with the schedule we were promised at the outset."
Punctual crews and steady pacing. A few reviewers describe crews as punctual and the process as moving at the expected pace. That points to a generally workable timeline when the project is managed smoothly. Representative review excerpt: "The crew was very friendly and punctual and the owner Matt was available and answered all of my questions."
Delays and closeout issues. Other reviewers report long waits, repeated follow-ups, and delays tied to getting the system fully up and running. These complaints make timeline reliability a clear watch-out in the review set. Representative review excerpt: "It took more than 6 months and a lot of calls and emails to get the solar up and running."
Workmanship & site care
Workmanship7.7/10
Most reviewers describe strong workmanship, clean installations, and professional crews. There are a few complaints about installation errors or site-plan problems, but the overall feedback remains comfortably positive.Solar.com's composite of published customer feedback, not a customer quote
Clean, professional installs. Several reviewers praise the installation quality, describing the work as clean, attractive, and carefully done. They also mention crews who were friendly and respectful of the property. Representative review excerpt: "The equipment was installed super clean and aesthetically pleasing."
Careful site protection. Some reviewers say the team avoided damage to the home and yard and left the site in good shape. That suggests attention to cleanup and site care was a strength for many customers. Representative review excerpt: "I really appreciated how careful they were in making a clean installation without harming my home or yard."
A few installation mistakes. A small number of reviewers report panels or components being installed incorrectly or not matching the agreed site plan. These complaints indicate occasional workmanship issues that required extra correction. Representative review excerpt: "Furthermore the inspector noticed many panels install incorrectly as well as other system components."
Long-term support & performance
Long-Term Support7.4/10
Post-install feedback is mostly positive, with some reviewers saying the system worked as expected and follow-up service resolved concerns. Still, several complaints mention delays, authorization issues, or system problems after installation, so support is not uniformly smooth.Solar.com's composite of published customer feedback, not a customer quote
Post-install problems on some jobs. Other reviewers describe delays around approval or concerns about how the system was set up, which affected their experience after installation. Those reports keep this category in mixed territory rather than strongly positive. Representative review excerpt: "He said at the time he was still waiting authorization from SDG&E to have our system approved before 'going live'."
Helpful post-install support. Some reviewers say follow-up service was responsive and helped them get questions answered or issues resolved after the system was in place. That points to at least some ongoing support after the initial job. Representative review excerpt: "He walked us through every step of the process and answered questions that we had (if you know me, you know I ask a lot of questions)."
Systems working as expected. A few reviewers report that their systems performed fine after follow-up and that issues were addressed successfully. These comments support a generally positive view of long-term performance for satisfied customers. Representative review excerpt: "Matt came to our house to do a checkup on our system and everything works fine now."
