How does High Definition Solar 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 High Definition Solar 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.

High Definition Solar 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 Integrity4.3/10

Reviewers give a mixed-to-negative picture of the sales process. Many describe clear explanations and helpful follow-through, but complaint patterns around pressure, poor responsiveness, and contract or proposal expectations are substantial.Solar.com's composite of published customer feedback, not a customer quote

Pressure and outreach complaints. Other reviewers report aggressive or unwanted outreach, including repeated calls, unexpected visits, and difficulty getting basic information. These complaints suggest that first-contact experiences can feel intrusive or hard to manage. Representative review excerpt: "They showed up at my house unexpectedly and helped themselves into my backyard, not cool when I am a woman living alone and see a stange man creeping around in..."

Proposal and contract expectations. Reviewers also mention unclear proposals, price issues, or promises that were not reflected later in the process. The recurring theme is that some customers felt the initial sales presentation did not match the final outcome.

Helpful when the process goes well. Some reviewers describe a smooth sales experience and say the company was helpful on repeat projects or larger system work. These comments point to clear guidance and a team that can earn trust with some customers. Representative review excerpt: "Because of the good service we received in 2020, we decided to expand our panels again in 2023 for going green and again High Def Solar helped us a lot..."

Price & financing transparency

Price Transparency4.0/10

Price and financing feedback leans negative. While some reviewers describe reasonable charges or a well-planned process, many others report unclear quotes, price increases, and concerns about deposits, refunds, or final pricing.Solar.com's composite of published customer feedback, not a customer quote

Unclear quotes and missing breakdowns. Several reviewers say they received quotes without enough detail, or that the numbers were presented in a way that made it hard to understand the full cost. This pattern suggests transparency problems around how pricing is explained. Representative review excerpt: "Doesn't bother emailing the quote and just spits out a number on a piece of paper with no price breakdown or itemized list."

Price changes and surprise cost concerns. Other reviewers report contract changes, unexpected increases, or quotes they felt were far above what they expected. These comments make pricing one of the clearest complaint areas in the review set. Representative review excerpt: "The experience has been horrible the first sales guys messed up the contract and tried to increase it by 6k then the installers left garbage all over my property and..."

Some reviewers found pricing reasonable. A smaller set of reviewers say the pricing felt fair or the overall plan was well organized. These comments frame the company as workable on cost for at least some jobs. Representative review excerpt: "Their charges were very reasonable, and the entire experience was seamless, from the prompt response to the professional installation."

Communication & coordination

Communication5.6/10

Communication is one of the more balanced categories, with many reviewers praising responsiveness and active follow-up. Still, a meaningful share describe missed callbacks, broken promises, or difficulty getting project updates and ownership.Solar.com's composite of published customer feedback, not a customer quote

Responsive support for many customers. Many reviewers say staff answered quickly, stayed engaged, and followed up multiple times to make sure issues were resolved. These comments suggest the company can be attentive once a project is underway. Representative review excerpt: "Thank you High Definition Solar for responding so quickly to address the issue with my system and a huge thank you to Eliud for patiently explaining the system, the problem..."

Good coordination on some projects. Some customers describe smooth communication during installation and say the team kept them informed when service was needed. This points to solid coordination in a number of successful cases. Representative review excerpt: "I got a call from the technician and the inside manager a total of 4 times to make sure it was taken care of and working."

Missed calls and weak follow-through. Other reviewers report repeated calls without response, slow callbacks, or promises that were not kept. The complaint pattern centers on inconsistent project ownership and uneven customer support. Representative review excerpt: "No return calls, broken promises, and customer service from hell."

Timeline reliability

Timeline Reliability6.0/10

Timeline feedback is moderately positive overall, with many reviewers saying work moved on schedule and was completed as planned. Even so, some reviewers report delays tied to design, inspections, or activation, and a few describe long waits before the system was running.Solar.com's composite of published customer feedback, not a customer quote

On-schedule work in many reviews. Many reviewers say the crew arrived when promised and the project moved forward on time. These comments suggest the company can meet schedules on a meaningful share of jobs. Representative review excerpt: "Their workmanship was first class, and everything was done on time, as scheduled."

Fast completion in some cases. Some customers describe quick turnaround, including projects completed in just a few hours once work began. This supports the view that the company can move efficiently when planning and execution line up. Representative review excerpt: "They even handled cleanup and painting when they installed the new electric panel and solar panels (all on the same day and in a few hours)."

Delays and missed milestones. Other reviewers report extended waits, failed inspections, or progress dates that did not match what they were told. These complaints show that permitting and activation can still slip behind expectations. Representative review excerpt: "Lack of communication, misrepresentation on progress and completion date, and already failed one city inspection due to the technician not completing the work and not being present the day of..."

Workmanship & site care

Workmanship7.4/10

Reviewers often describe professional crews, clean job sites, and solid installation quality, though a smaller set raise concerns about leaks, cleanup, or work that needed follow-up.Solar.com's composite of published customer feedback, not a customer quote

Professional crews and clean installs. Many reviewers say the installation team was prompt, professional, and careful on site. These comments suggest the crew experience is often a strong part of the job. Representative review excerpt: "The crew arrived at exactly 8:oo AM as promised and were completely finished at 2:00 pm."

Strong installation quality. Some reviewers describe the workmanship as first class and note that the job was completed as promised. This reflects a generally positive view of how the physical install is handled. Representative review excerpt: "Today Marshall returned as promised and spent 5 hours replacing the wiring to each panel and the junction box as well as the wiring to our Enphase box at ground..."

Site and repair concerns. A smaller group reports leaks, debris left behind, or repair-related issues after installation. The complaint pattern is present but less common than the praise in this category. Representative review excerpt: "On March 28, 2024, i sent an email to the company in regard to this leak in the location where the solar panels were installed, no reply back."

Long-term support & performance

Long-Term Support5.0/10

Long-term support and post-install performance are mixed, with many reviewers describing helpful follow-up and working systems, but a notable set reporting monitoring gaps, warranty frustrations, or delayed service. The category suggests better experiences once support is engaged, though not consistently.Solar.com's composite of published customer feedback, not a customer quote

Helpful follow-up after installation. Some reviewers say the company continued to help after the system was up and running and responded when service was needed. These comments indicate that post-install support can be effective in some cases. Representative review excerpt: "Our system out does our neighbors love our panels and the continued help from the staff."

Monitoring and service gaps. Other reviewers report systems being offline for long periods or say they were not alerted by monitoring when a problem developed. This points to concerns about how reliably issues are detected and handled after activation. Representative review excerpt: "Panels were offline for months and smud came out and notified me of a problem not the supposed 24 hour monitoring system they have tracking the panels."

Warranty repair delays. Some customers describe repeated attempts to get warranty repairs completed and say they had trouble getting responses. The recurring complaint is that post-install support can be slow or hard to reach when problems arise. Representative review excerpt: "Called left messages for warranty repairs, this is now the 2nd issue that we have had with this business."

Bottom line: Across 333 substantive reviews, HIGH DEFINITION SOLAR earns an overall Solar.com installer score of 5.9/10, which points to a mixed customer experience. The strongest themes are better workmanship and decent communication for many projects, while the clearest complaint patterns involve sales/proposal clarity, pricing transparency, and inconsistent post-install support.

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.
