How does Starpower Systems 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 Starpower Systems 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.

Starpower Systems 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 Integrity7.2/10

Reviewers generally describe the sales process as clear and informative, with several saying the team explained options, technical details, and next steps before contracts were signed. A small number of comments raise concerns about how some requirements were communicated, so the overall picture is positive but not flawless.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations. Reviewers frequently say the sales process included detailed walkthroughs of system options, technical considerations, and project steps. Several also describe the quote-to-installation flow as organized and easy to follow. Representative review excerpt: "Matthew was very friendly to work with, but more importantly he walked me through my options and explained in detail the system and all of the steps along the way."

Straightforward process. Some reviewers say the whole process, from quote through permits and utility steps, felt well managed and well explained. They point to a sales experience that set expectations early. Representative review excerpt: "The whole StarPower process was excellent with the whole team from quote to site visit to plans, approvals, permits, and PG&E process."

Communication gap on requirements. One reviewer reports that a contract-related requirement was not clearly communicated at the quote stage. This appears as an isolated complaint within an otherwise favorable pattern. Representative review excerpt: "This should have been communicated with quote and note that they can't do contracts until it's fixed and license is valid."

Price & financing transparency

Price Transparency7.0/10

Feedback on pricing and financing is mostly favorable, with reviewers often describing the company as transparent about options and cost structure. The review set does not show a notable pattern of surprise charges or financing confusion, though some comments emphasize that pricing discussions were part of a broader consultative process.Solar.com's composite of published customer feedback, not a customer quote

Transparent pricing discussions. Reviewers say the team explained pricing, options, and project scope in a way that made the proposal easier to understand. Several comments suggest the company focused on helping customers evaluate what they needed before moving forward. Representative review excerpt: "With StarPower, I got a visit from the owner, whose expertise was manifest, and who talked to me about what I needed rather than about what he wanted to sell."

Helpful walkthrough before signing. Customers also describe receiving detailed explanations before contracts were signed, including time spent discussing technical and financial details. That comes through as a strong point in the pricing experience. Representative review excerpt: "Matthew was very friendly to work with, but more importantly he walked me through my options and explained in detail the system and all of the steps along the way."

No major surprise-cost pattern. Across the available reviews, there is no recurring complaint pattern about unexpected fees, deposits, or financing surprises. The main theme is clarity rather than confusion. Representative review excerpt: "Being in Silicon Valley and have been an HR professional in the valley growing tech companies where it's tough to get good help, Matthew was transparent about his challenges in..."

Communication & coordination

Communication7.4/10

Most reviewers report responsive communication, regular follow-up, and hands-on coordination from the team. A smaller set of comments mentions delays in callbacks, invoices, or email follow-up, so communication is a strength with some uneven spots.Solar.com's composite of published customer feedback, not a customer quote

Responsive follow-up. Many reviewers say the team responded quickly, stayed in touch, and helped troubleshoot issues as they came up. Several also mention friendly, caring support during the project. Representative review excerpt: "They responded right away and they kept in touch, trying to trouble shoot, great communication, friendly, and caring."

Hands-on ownership. Customers describe team members stepping in personally to troubleshoot, provide app guidance, and help keep projects moving. That suggests strong ownership once a project is underway. Representative review excerpt: "Matt came out personally and troubleshooted the system, got our solar back up and working and provided us with solar app information so now we can see our energy storage."

Occasional follow-up delays. A few reviewers report slower communication around invoices, callbacks, or service follow-up. These comments do not dominate the feedback, but they do show that responsiveness is not uniform across every case. Representative review excerpt: "My only criticisms are that it took a few weeks to get a final invoice and that I was ghosted on my communication with Matt about a service panel upgrade..."

Timeline reliability

Timeline Reliability6.7/10

Timeline feedback is mixed-to-positive: many reviewers say permitting, inspections, and installation moved smoothly, but a few note delays tied to parts availability or project scheduling. The category score reflects that the company often keeps projects moving, while some customers experienced longer-than-expected waits.Solar.com's composite of published customer feedback, not a customer quote

Permits and inspections handled well. Several reviewers say the team helped work through city permitting and inspection steps, with projects moving through approvals in an organized way. These comments point to solid coordination on the administrative side of the timeline. Representative review excerpt: "In addition they worked with the city of campbell to assist us with a new permit so everything could be squared away."

Efficient completion in some cases. Some customers describe the installation itself as smooth and fast, including projects finished in record time. That suggests the team can move efficiently when materials and scheduling align. Representative review excerpt: "Our experience with them was smooth and not only did they finish the installation, but also did it in record time!"

Delays and stock issues. A few reviewers report longer waits tied to installation timing, missing parts, or backordered equipment. These complaints are not the majority, but they show that timeline reliability can vary. Representative review excerpt: "during our installation, the battery was out of stock for a extended period but he has the plan to make customers happy."

Workmanship & site care

Workmanship7.8/10

Reviewers generally praise the installation quality, crew professionalism, and attention to detail. The small number of complaints center on follow-up for parts or fixes rather than a broad pattern of workmanship problems.Solar.com's composite of published customer feedback, not a customer quote

Clean, professional installs. Customers often describe the crew as professional and the work as well executed. Some say the installation passed inspection on the first try, which supports a strong workmanship impression. Representative review excerpt: "The job was nicely done and passed inspection the first time!"

Attention to roof and layout details. Several reviewers say the team took roof placement and site requirements seriously and made thoughtful installation choices. That suggests attention to detail during the site work itself. Representative review excerpt: "Luckily I had several roof placement options but only Matt took this requirement seriously and he went to some trouble to use parts of my roof where the panels could..."

Follow-up on missing parts. One reviewer reports that a needed part was not available during a service visit and the issue had to be revisited later. This is a limited complaint, but it points to occasional site-care or closeout gaps. Representative review excerpt: "They identified the issue to be a failed fuse but since they didn't have it they promised to come back."

Long-term support & performance

Long-Term Support6.8/10

Post-install feedback is mostly positive, with many reviewers saying the company responded to system issues, provided troubleshooting, and helped customers understand monitoring and app tools. The lower score reflects a few complaints about repair timing or post-install milestones not being completed as quickly as expected.Solar.com's composite of published customer feedback, not a customer quote

Responsive troubleshooting. Several reviewers say the team returned to troubleshoot problems, restored system function, and helped with monitoring or app setup. These comments suggest solid hands-on support after the system is running. Representative review excerpt: "Matt came out personally and troubleshooted the system, got our solar back up and working and provided us with solar app information so now we can see our energy storage."

Long-term customer care. Some customers say the company continued to help after installation and showed willingness to support the system over time. That is a recurring positive theme in the post-install feedback. Representative review excerpt: "They take care of their customers over the long term, which I appreciate."

Service timing concerns. A small number of reviewers mention delayed post-install milestones or repair timing that felt slower than expected. The complaints are limited, but they show that support timing can be uneven. Representative review excerpt: "It is now mid September still not passed NEM."

Bottom line: Across 36 substantive reviews, STARPOWER SYSTEMS earns an overall Solar.com Installer Score of 7.9/10, with strongest feedback around workmanship, communication, and clear sales explanations. The main watch-outs are timeline reliability and some post-install support timing, where a few reviewers describe delays or follow-up gaps.

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.
