How does Sutro Power 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 Sutro Power 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.

Sutro Power 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 Integrity7.5/10

Reviewers describe Sutro Power’s sales process as clear, professional, and low-pressure. Feedback most often centers on straightforward explanations, careful proposal review, and help setting expectations about scope and process.Solar.com's composite of published customer feedback, not a customer quote

Clear, careful proposals. Reviewers say the team took time to answer questions, explain design choices, and walk through the proposal in detail. Several describe the process as honest and easy to understand. Representative review excerpt: "Even during the busy time, their team took the time to answer questions and plan solar for our multi unit building!"

Professional, low-pressure approach. Customers often report that JP and the team were professional, timely, and straightforward, with a presentation style that helped them feel comfortable moving forward.

Contract and process clarity. Reviewers also note that the team handled inspections and applications and helped set expectations around the project workflow, which reinforced trust in the initial agreement. Representative review excerpt: "They handled all the inspections and applications, and as a small, local business, we feel confident that they will be responsive to any questions or concerns we have in the..."

Price & financing transparency

Price Transparency6.9/10

There is one complaint-related review in this category, so the overall picture is positive but not perfectly uniform.Solar.com's composite of published customer feedback, not a customer quote

Pricing pricing. They also describe the team as straightforward about cost and scope. Representative review excerpt: "They are knowledgeable and reliable, and their pricing is very competitive - substantially better than the quotes I got from national chains."

Clear price and contract discussion. Customers report that the design, scope of work, contract, schedule, and price were explained in a direct way. That clarity appears to have reduced uncertainty around the final agreement. Representative review excerpt: "JP and Juliano were very straightforward and easy to work with on the design, their scope of work, the contract, their schedule and the price."

Incentive timing watch-out. One reviewer references incentive timing as part of the overall wait before the project moved forward. The review set contains only a small amount of negative feedback on pricing and financing. Representative review excerpt: "We waited a bunch of months and then bam, it was our turn :) may be less of an issue now that the NEM 2.0 deadline is in the past."

Communication & coordination

Communication7.7/10

Reviewers describe Sutro Power as responsive and hands-on, with frequent check-ins and clear ownership of the project. Most feedback is positive, though one review describes a long wait before the project reached its turn in the queue.Solar.com's composite of published customer feedback, not a customer quote

Responsive follow-through. Customers say the team is quick to respond when issues come up and that they stay engaged through the project. This is one of the most consistently praised parts of the review set. Representative review excerpt: "If anything comes up they are super responsive."

Active project oversight. Reviewers note regular check-in calls, onsite visits, and practical guidance when the team saw problems in prior designs. This suggests strong coordination across estimate, install, and follow-up. Representative review excerpt: "From estimate to install, JP oversaw that everything was going accordingly by making regular check-in calls and driving also by driving down to Palo Alto for "house calls"."

Queue timing watch-out. One reviewer describes a long wait before the project was scheduled, even though the eventual communication was positive. That complaint appears isolated rather than common. Representative review excerpt: "We waited a bunch of months and then bam, it was our turn :) may be less of an issue now that the NEM 2.0 deadline is in the past."

Timeline reliability

Timeline Reliability7.3/10

Reviewers generally report that Sutro Power manages permitting, scheduling, and activation well. The main caution is that one review describes a long delay before work began, while most others describe the timeline as smooth or flexible.Solar.com's composite of published customer feedback, not a customer quote

Permitting and local process knowledge. Customers say the team understands local permitting and can explain the steps involved in multi-unit or complex projects. That familiarity appears to help the work move forward more predictably. Representative review excerpt: "Local operator who understands San Francisco permitting well, and also could walk me through details on whether to tie in multiple meters in my multi unit 4 apartment building or..."

Flexible scheduling. Reviewers also describe the company as willing to adjust timing when roof work or other site conditions required a delay. That flexibility helped some projects fit the customer’s schedule. Representative review excerpt: "They kindly agreed to postpone the installation of two of the panels for almost six months while we completed other work on the roof."

Delay watch-out. One reviewer reports waiting several months before the project was scheduled. This is the main timeline complaint reflected in the review set. Representative review excerpt: "We waited a bunch of months and then bam, it was our turn :) may be less of an issue now that the NEM 2.0 deadline is in the past."

Workmanship & site care

Workmanship7.9/10

Reviewers typically describe the installation crews as professional and the finished work as high quality. A small number of comments point to minor improvement areas, but the dominant pattern is satisfaction with the install and cleanup.Solar.com's composite of published customer feedback, not a customer quote

Professional crews and cleanup. Customers say the crews were friendly, professional, and careful to clean up afterward. These reviews suggest solid site care during and after installation. Representative review excerpt: "They were friendly, professional, and made sure to clean up afterward."

Troubleshooting and fix-ups. Reviewers mention the team staying with difficult integration issues until the system worked, including follow-up corrections after the initial install. That persistence is a recurring strength in the workmanship feedback. Representative review excerpt: "There were some issues integrating that battery with my old system, but the Sutro team kept troubleshooting until it worked."

Minor field-process note. One review mentions a small improvement area around when roof work is done during the day. The comment reads as a minor site-practice note rather than a major workmanship complaint. Representative review excerpt: "Only real thing to improve would be getting crews to do more of the active roof work earlier in the day when the shingles are cooler and would get less..."

Long-term support & performance

Long-Term Support7.7/10

Reviewers report strong post-install support, including troubleshooting, monitoring-related fixes, and follow-up service after the system is running. The review set is uniformly positive in this category, with no meaningful complaint pattern visible.Solar.com's composite of published customer feedback, not a customer quote

Post-install troubleshooting. Customers describe the team returning to solve integration and performance issues after activation. Reviewers present this as evidence of real long-term support rather than one-time installation work. Representative review excerpt: "The co-owner, JP Rapagnani, took us on, attracted the attention of Solar Edge, came onsite and got the battery reconnected and updated, installed optimizers on three dark panels, and, finally..."

Ongoing service after turn-on. Several reviews note continued help once the system was live, including attention to equipment updates and other follow-up needs. That suggests the company stays involved after the initial install. Representative review excerpt: "We have had our 4.1kW solar panel, and Powerwall 3 system up and running for almost 2 months now."

Support-oriented ownership. Reviewers also describe JP as someone who remained engaged across the life of the project and helped address issues as they came up. The category contains no notable complaints in the reviewed set. Representative review excerpt: "I suppose my situation was quite different than most because I wanted the system to be integrated into everything I was were trying to do with the house at the..."

Bottom line: Solar.com’s review corpus for Sutro Power is strongly positive overall, with an installer score of 8.2/10 and especially consistent praise for communication, sales clarity, and post-install support. The main watch-outs are occasional timeline delays and a small number of pricing or site-process concerns, but those issues appear rare in the reviewed set.

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.
