How does Guyou 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 Guyou 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.

Guyou Construction 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 Integrity6.4/10

Reviews on sales and proposal integrity are mostly positive, with many customers describing clear explanations, helpful follow-through, and a professional handoff into installation. At the same time, a meaningful minority reports concerns about overpromising, unclear contract expectations, or feeling they had fewer rights or options than expected.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations and follow-through. Reviewers often say the sales process was straightforward and that the company followed up to make sure the system and next steps were understood. Representative review excerpt: "Once completed they did a follow up to ensure my understanding of how the new solar system would work and made sure everything was done to my complete satisfaction."

Helpful sales guidance. Some customers describe sales staff as supportive and informative during the proposal stage, including advice that helped with the overall decision process. Representative review excerpt: "And a very special Thank you to salesman Grady DenBoer in Utah who helped us with advice and helped us with the sale of our roof."

Proposal or contract concerns. Other reviewers report feeling that the sales process did not fully match expectations, including concerns about how contracts were framed and what rights or options were available. Representative review excerpt: "7_When I objected to the matter, the made sure that the contract is prepared such that you have minimum rights for example if the production reduces substantially after each rain..."

Price & financing transparency

Price Transparency5.8/10

Feedback on pricing and financing is mixed.Solar.com's composite of published customer feedback, not a customer quote

Upfront pricing and value. Reviewers describe a recurring pattern in this area. Representative review excerpt: "Recently had them come out to service my solar, they provided up front pricing and were on time."

Pricing deal for the project. Some customers describe the overall price as a strong value and note that the process stayed on budget or felt reasonably priced. Representative review excerpt: "This is the best prices and installation process we got for solar in inland empire."

Unexpected cost concerns. Other reviewers report confusion about final costs or service charges, including concerns about paying more than expected without enough explanation. Representative review excerpt: "I made the big mistake of directly hiring Guyou construction and I paid a lot more without knowing my rights and options and received a non-optimal solar."

Communication & coordination

Communication8.4/10

Communication and coordination are a clear strength overall. Reviewers frequently mention responsive staff, helpful scheduling, and regular updates, while the smaller set of complaints centers on delayed replies, missed follow-up, or occasional project confusion.Solar.com's composite of published customer feedback, not a customer quote

Responsive, helpful communication. Many reviewers say the team stayed in touch well, answered questions promptly, and kept them updated through the project. Representative review excerpt: "They communicated very well and did very good work."

Helpful scheduling and follow-through. Customers also mention staff who were helpful by phone and on site, especially around scheduling and coordination with different crews. Representative review excerpt: "Their customer service rep on the phone handling the scheduling, Jennifer and the guys Ralph, and Brandon were very helpful."

Delayed responses in some cases. A smaller group reports difficulty getting timely responses when service questions or billing concerns came up. Representative review excerpt: "I have sent numerous messages to the sales rep, Roland, and their technician over the past 3 weeks without response regarding exorbitantly high SCE monthly bills recently."

Timeline reliability

Timeline Reliability8.1/10

Timeline feedback is generally favorable, with many reviewers saying installations and inspections moved along smoothly. The main watch-outs are permitting, inspection, and utility-activation delays, which some customers describe as longer than expected but not severe in every case.Solar.com's composite of published customer feedback, not a customer quote

Smooth project flow. Reviewers often describe the job as organized and say the process moved through installation and inspection without major issues. Representative review excerpt: "They left the site clean and all inspections were completed as scheduled."

Clean completion of visits. Some customers say the team finished installation and inspection visits efficiently and left the job site in good condition each time. Representative review excerpt: "Over the installation and inspection visits, the team finished the job without any loose ends and a cleaned up job site each time."

Waiting on approvals or activation. Other reviewers note delays tied to city approvals, inspections, or utility permission to operate, which extended the time to turn the system on. Representative review excerpt: "My panels look great, low profile and now just waiting to get approvals from the city to turn on."

Workmanship & site care

Workmanship9.0/10

Workmanship and site care receive very strong feedback. Reviewers commonly describe professional crews, careful installation, clean job sites, and solid overall execution, while complaints are relatively rare and usually focus on cleanup or installation-detail issues.Solar.com's composite of published customer feedback, not a customer quote

Professional installation crews. Many reviewers praise the installers as knowledgeable and professional throughout the job. Representative review excerpt: "From the initial consultation to the final installation, their team was professional, knowledgeable, and communicative every step of the way."

Clean job sites. Customers frequently mention that the team left the site clean and handled the work neatly from start to finish. Representative review excerpt: "Explained what was being done and left the job clean."

Cleanup and site-protection issues. A small number of reviewers say there was debris or other cleanup-related concerns after the work was done. Representative review excerpt: "The roofers and the solar install crews both left quite a bit of trash on the roof, which obviously blows off eventually."

Long-term support & performance

Long-Term Support8.7/10

Post-install support and system performance are rated positively overall. Reviewers often report that the system works well, that fixes were handled quickly, and that support was helpful after installation, though a smaller group says follow-up was slower than expected or that performance concerns took time to resolve.Solar.com's composite of published customer feedback, not a customer quote

Strong system performance. Many reviewers say the system has worked as expected and, in some cases, helped reduce monthly electric bills. Representative review excerpt: "System works as expected, great savings on my monthy electric bill."

Quick repair and reset support. Customers also describe fast help after installation, including repairs or resets that restored operation quickly. Representative review excerpt: "He finished the repair quickly, verified everything was working correctly, and cleaned up everything when he finished."

Post-install follow-up concerns. A smaller set of reviews says they had difficulty getting responses after completion or still needed help with performance issues. Representative review excerpt: "I have been calling and calling and no response."

Bottom line: GUYOU CONSTRUCTION’s review profile is strongest in workmanship, communication, and long-term support, with most customers describing professional crews and solid follow-through. The main caution areas are sales/proposal expectations and pricing transparency, where some reviewers report unclear contract details, cost surprises, or slower issue resolution after installation.

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.
