#66 of 678 scored in California by Solar.com Installer Score

How does Alltech 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 Alltech 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.

Alltech Solar 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 Integrity7.9/10

Reviewers mostly describe clear, fair sales interactions and say the proposal process matched expectations. A small number of complaints mention disagreement over recommendations or a sense that expectations were not aligned, but those reports are limited in the review set.Solar.com's composite of published customer feedback, not a customer quote

Clear and fair proposals. Many reviewers say the sales process felt honest, straightforward, and knowledgeable, with expectations explained clearly before the job began. Representative review excerpt: "Very honest and fair, and very good at making the repair and knowledgeable about the whole process and SolarEdge inverter."

Comfort with the quote and process. Some customers describe feeling confident in the proposal and say the quote and overall presentation made the decision easier. Representative review excerpt: "I went with Alltech based on a recommendation of a friend who was very pleased with his installation with Alltech as well as their great quote in comparison to other..."

Isolated dissatisfaction with recommendations. A few complaints describe disputes over placement recommendations or say a negotiated understanding was not reflected in the final experience. Representative review excerpt: "I was deceived by AllTech Solar after a negotiated agreement with the sales representative, Ken Ehrle."

Price & financing transparency

Price Transparency7.4/10

Reviewers generally report clear cost discussions and acceptable pricing, including support around rebate-related timing questions. A small set of complaints raises concerns about added charges, deposit handling, or how certain expenses were explained.Solar.com's composite of published customer feedback, not a customer quote

Costs explained clearly. Several reviewers say the company was clear about pricing and costs, which helped set expectations before work started. Representative review excerpt: "Explained every step and was clear on costs."

Helpful on pricing and support. Some customers describe strong value and responsive follow-up when they needed help after the initial installation. Representative review excerpt: "Lost my solar installer call Alltech Solar to the rescue and for a great price made the repair and solar up and running full strength once again."

Disputes over fees and payments. A few reviewers report concerns about permit-related charges or how payments and expenses were handled after the fact. Representative review excerpt: "They sent a weak memo and claimed to have permit expenses equal to my payment, which the city confirmed no payments were made by AllTech, no required permit application with..."

Communication & coordination

Communication7.8/10

Most reviewers describe responsive communication, steady updates, and a team that stayed engaged through the project. The main complaint pattern is that some customers say messages and calls went unanswered or that follow-through fell short after the sale.Solar.com's composite of published customer feedback, not a customer quote

Frequent updates and responsiveness. Many reviewers say the team kept them informed, answered questions promptly, and made the process feel organized. Representative review excerpt: "Chase (the owner) and his team were always on time, finished the work on schedule, kept me updated throughout the entire process, and did clean, high-quality work."

Strong overall coordination. Some customers describe the team as easy to work with and say follow-up support was responsive when adjustments were needed. Representative review excerpt: "What really stands out is their ongoing support — they’ve been very responsive whenever we’ve had follow-up questions or needed adjustments."

Unanswered messages. A portion of complaints says emails, texts, and calls were not returned, leaving customers waiting for help or information. Representative review excerpt: "They don't reply to email or phone call or texts."

Timeline reliability

Timeline Reliability7.7/10

Reviewers often say projects moved on schedule, with permits, inspections, and final sign-off handled cleanly. The complaints focus on delays in permitting or activation-related follow-through, along with a few reports of missed details after installation.Solar.com's composite of published customer feedback, not a customer quote

On-time project flow. Many reviewers say the crew arrived when expected, finished on schedule, and kept the project moving without major delays. Representative review excerpt: "Chase (the owner) and his team were always on time, finished the work on schedule, kept me updated throughout the entire process, and did clean, high-quality work."

Permits and inspections handled. Some customers report that the company managed permits, inspections, and final approval as part of a smooth process. Representative review excerpt: "Everything was handled: on-site inspection, quote, permits, So Cal Edison, city inspection, and final sign off."

Delays and missed follow-through. A few complaints mention longer-than-expected timelines, permit issues, or incomplete post-installation activation steps. Representative review excerpt: "I understand the desire as a business to bite off more than you can chew, but the result was significantly delayed timelines, poor communication, and a lack of transparency."

Workmanship & site care

Workmanship8.9/10

This is one of the strongest categories in the review set. Reviewers overwhelmingly describe clean, professional installations and say the crews handled complex work well, while only a few complaints mention property damage or cleanup concerns.Solar.com's composite of published customer feedback, not a customer quote

Professional, smooth installation. Many reviewers say the installation itself was smooth and professional, with crews handling the job carefully from start to finish. Representative review excerpt: "They installed an Enphase solar system with battery backup at our home, and the entire process was smooth and professional."

Good results on complex projects. Some customers describe multi-step projects that included panels, batteries, panels, and inspection approval, and say the work was handled well. Representative review excerpt: "The project included upgrading and relocating the power panel, working with SDGE, installing the panels and getting the projects approved by the city inspector."

Property damage concerns. A small number of complaints mention damage to landscaping or home surfaces during installation. Representative review excerpt: "When they came to install the new electrical panel, required for solar, they ripped out a $50 hibiscus plant and just tossed it aside like it was garbage, plus a..."

Long-term support & performance

Long-Term Support8.1/10

Reviewers mostly report strong system performance after installation, including good production, successful repairs, and helpful follow-up support. The complaint pattern centers on slow post-install support, monitoring or registration issues, and difficulty getting service when something needed attention.Solar.com's composite of published customer feedback, not a customer quote

Reliable system performance. Many reviewers say their systems performed as expected after turn-on and continued working well over time. Representative review excerpt: "very clean job, Chase responded to questions promptly, system worked as expected and still working well 6yrs later."

Helpful repair and follow-up support. Some customers say the company responded quickly to service needs and got systems back up and running promptly. Representative review excerpt: "A technician showed up promptly, replaced the board, and got our system back up and running immediately."

Post-install support issues. A number of complaints describe trouble getting help after installation, including monitoring, registration, or repair follow-up problems. Representative review excerpt: "We have been trying to reach them for a more than month through emails about faulty solar panel replacement."

Bottom line: ALLTECH SOLAR’s review profile is strongly positive overall, with especially high marks for workmanship and solid ratings across sales, coordination, timing, pricing, and post-install support. The main watch-outs are a smaller set of complaints about communication gaps, permit or timeline delays, and follow-through after the project is complete.

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.
