How does All Bay Solar Construction 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 All Bay Solar Construction 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.

All Bay Solar Construction 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 Integrity7.7/10

Reviewers mostly describe the sales and proposal process as clear, helpful, and low-pressure. The main complaints are rare, but a small number of reviewers report concerns about how pricing or included work was presented.Solar.com's composite of published customer feedback, not a customer quote

Clear proposals and guidance. Reviewers frequently say the team took time to explain options, walk through recommendations, and make the process easy to understand. Several describe the proposal stage as straightforward and professional. Representative review excerpt: "They did a site survey and put together a proposal with their recommendations, and then spent time talking through options."

Helpful, low-pressure sales experience. Many customers report that the team was friendly, honest, and responsive during the sales process, with explanations that made the technology easier to follow. Representative review excerpt: "They were friendly and honest, and spent time making sure I understood the technology and the options."

Occasional concerns about sales clarity. A small number of reviewers describe concerns about what was being sold or about added work they did not expect, suggesting occasional gaps in expectation-setting. Representative review excerpt: "The sales rep was not on the up and up regarding what your buying."

Price & financing transparency

Price Transparency7.0/10

Feedback on pricing and financing is mostly positive, with many reviewers describing reasonable pricing and timely handling of project timing around incentives. Still, this category is more mixed than the others because a few reviewers report confusion or dissatisfaction tied to pricing-related expectations and system details.Solar.com's composite of published customer feedback, not a customer quote

Reasonable pricing and responsiveness. Some reviewers describe the pricing as reasonable for the work delivered and say questions were answered promptly during the process. Representative review excerpt: "The whole team at All Bay is responsive, reliable, kind, professional and and their pricing is reasonable for top notch work."

Incentive timing handled well. Reviewers also note that the team completed projects in time for incentive timing or other schedule-sensitive milestones, which they appreciated. Representative review excerpt: "Most importantly, the team was able to complete the installation in time for us to qualify for the end-of-year tax incentive, which we really appreciated."

A few pricing or scope concerns. A small set of reviewers report confusion or dissatisfaction related to how work was priced or how the final setup functioned, indicating occasional transparency issues. Representative review excerpt: "I do not understand why my generator doesn't supply power to my home, My Generator Guy said it does not provide power because the generator was partial connected to subpanel."

Communication & coordination

Communication8.1/10

Most reviewers describe communication as responsive, courteous, and organized, especially when it came to updates and follow-through. The complaint pattern is limited but includes some reports of slow replies, less structure after signing, or gaps in follow-up.Solar.com's composite of published customer feedback, not a customer quote

Responsive project support. Reviewers often say the team replied quickly, answered questions patiently, and kept them informed as the project moved forward. Representative review excerpt: "I tend to ask a lot of questions, and they were always responsive and courteous, despite it being an unusually busy time for everyone in the solar industry."

Hands-on coordination. Several customers report that project managers or team members stayed engaged through diagnosis, completion, and system walkthroughs, which made the process feel well managed. Representative review excerpt: "When everything was complete, Edgar, my project manager, powered up the system and took the time to show me how everything worked."

Some follow-up gaps. A few reviewers mention needing to follow up proactively or feeling that post-signing communication lacked structure, showing that coordination was not always consistent. Representative review excerpt: "Our only issue was that there were some hiccups with email communication and we would have liked a little more structure after signing the contract from the team."

Timeline reliability

Timeline Reliability7.9/10

Timeline feedback is largely positive, with many reviewers saying projects finished on time and aligned with expectations. A small number describe delays between stages or schedule-dependent frustrations, so the category is strong overall but not flawless.Solar.com's composite of published customer feedback, not a customer quote

Often on time and on budget. Many reviewers say the work was completed when promised and that the project stayed on schedule from planning through completion. Representative review excerpt: "They came to the house, sited the panels for maximal efficiency, created a plan and estimate, and then delivered on time and on budget."

Good handling of schedule-sensitive work. Some customers specifically note that the team finished in time for deadline-driven milestones, including incentive timing and other project goals. Representative review excerpt: "When we were planning the installation of our panels we had All Bay install a new roof because ours was about 15 years old and we wanted the roof to..."

Occasional delays between stages. A few reviewers describe waiting periods during the process, such as pauses between survey and the next step, which suggests some timeline variability. Representative review excerpt: "The process went in a few stages first they sent a team to perform a site survey from All Bay Solar once that was completed we had to wait for..."

Workmanship & site care

Workmanship8.7/10

Reviews of installation quality are mostly positive, with many customers praising professionalism, cleanup, and finished work. The main complaints are limited but include a few reports of installation or equipment issues that required correction.Solar.com's composite of published customer feedback, not a customer quote

Professional installation crews. Reviewers frequently describe the crews as professional, responsive, and careful during the install process. Representative review excerpt: "Every single member of their team was professional and responsive, getting back to me in a day or less and really going above and beyond to get me a working..."

Clean and efficient job sites. Some customers say the crew completed the job quickly and left the property clean and neat afterward. Representative review excerpt: "The crew had my job complete in one day and left the grounds clean and neat."

A few workmanship issues. A small number of reviewers report installation problems such as fit, sizing, or incorrectly completed work, indicating that site care was not perfect in every case. Representative review excerpt: "All Bay Solar came out initially and installed a new breaker panel which was undersized, and the inner cover never really fit over the breakers, bulging out at various points..."

Long-term support & performance

Long-Term Support8.8/10

Post-install feedback is mostly strong, with reviewers saying systems performed well and warranty or service follow-up was helpful. Complaints are rare but include a small number of service-related issues after installation.Solar.com's composite of published customer feedback, not a customer quote

Strong system results. Reviewers report good system performance after turn-on, including strong production and meaningful bill reduction in some cases. Representative review excerpt: "Allbaysolar installed three solar panel systems in our building and we’re enjoying almost zero bills from PGE."

Helpful warranty support. Several customers say they were happy with warranty service calls and post-install support from the team. Representative review excerpt: "I've been very happy w/All Bay Solar's warranty service calls."

Limited service complaints. A small number of reviewers describe unresolved service problems or additional repair costs after installation, which suggests occasional post-install support issues. Representative review excerpt: "In April, 2024 I paid $500 to a Generac certified generator repair technician to trouble shoot."

Bottom line: Across 126 substantive reviews, All Bay Solar Construction is described positively in most categories, with especially strong marks for workmanship and long-term support. The most mixed area is price and financing transparency, where reviewers generally stay positive but a few report confusion or dissatisfaction around pricing or scope. Complaints appear relatively uncommon overall, but they are present in each category and are most noticeable where expectation-setting and post-install support are involved.

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.
