How does Kota 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 Kota 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.

Kota Construction reviews: what customers say

An independent synthesis of published customer feedback, updated September 28, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity6.8/10

Reviewers most often describe the sales process as clear, helpful, and low-pressure, with several saying the rep stayed involved from the first conversation through project completion. At the same time, a meaningful minority report pushy or slick sales behavior, along with expectations that did not line up well with later follow-through.Solar.com's composite of published customer feedback, not a customer quote

Helpful guidance. Many reviewers say the sales team explained the process clearly and stayed engaged through the project, including helping customers understand billing and app usage after installation. Representative review excerpt: "His dedication shone through when he personally reviewed our first SDG&E bill post-installation, ensuring we understood the billing and app usage."

Low-pressure presentation. Some reviewers report a professional, patient sales approach with thorough explanations rather than hard selling. Representative review excerpt: "McKay came to my house as a very professional, pleasant and such a good listener without any sales pressure, but thorough explanation of the benefits of having a solar system..."

Sales follow-through complaints. Complaints in this area describe delays, poor communication after the sale, and cases where customers say promised help did not materialize. Representative review excerpt: "For the next month we called Kota incessantly, even calling the director of sales repeatedly, who even texted and emailed us that he would help, but did nothing and never..."

Price & financing transparency

Price Transparency4.9/10

Feedback on pricing and financing is mixed and leans negative. While some reviewers say the process was straightforward and helpful, others describe overcharges, confusing financing terms, and problems tied to deposits or refunds.Solar.com's composite of published customer feedback, not a customer quote

Smooth pricing experience. Some reviewers say the process felt smooth and that they were kept informed about timing and costs. Representative review excerpt: "The whole process went smoothly, professionally, quickly and KOTA kept me informed of events and timing."

Helpful explanation of value. A few customers describe the sales conversation as informative and money-saving without feeling pressured. Representative review excerpt: "McKay came to my house as a very professional, pleasant and such a good listener without any sales pressure, but thorough explanation of the benefits of having a solar system..."

Overcharge and financing disputes. Complaints describe overbilling relative to the quote, followed by contract and financing disputes that were not quickly resolved. Representative review excerpt: "Over charged from what was quoted then they sent out a new contract with correct price but still paying the over charged price as finance company says Kota needs to..."

Communication & coordination

Communication5.3/10

Many reviewers say they received frequent updates, good follow-through, and clear step-by-step coordination. However, a substantial set of complaints describes slow responses, repeated calls, and situations where customers felt left without ownership or timely answers.Solar.com's composite of published customer feedback, not a customer quote

Regular updates. Several reviewers say a project lead stayed engaged and kept them updated on progress throughout the job. Representative review excerpt: "Jared always stayed engaged in the process and kept us updated on all progress."

Good follow-through. Some customers describe the team as informative and consistently responsive at each step in the process. Representative review excerpt: "We have gotten great service, no hard sell, lots of good information, excellent follow through and always keeps us informed at each step in the process."

Delayed or missing responses. Complaints say communication broke down after the sale, with repeated calls, ignored concerns, and long stretches without meaningful follow-up. Representative review excerpt: "For the next month we called Kota incessantly, even calling the director of sales repeatedly, who even texted and emailed us that he would help, but did nothing and never..."

Timeline reliability

Timeline Reliability4.9/10

Some reviewers say installation and permitting moved quickly and were coordinated around their schedules. Still, complaints frequently focus on delays, missed timelines, and projects that stalled during permitting, inspection, or activation.Solar.com's composite of published customer feedback, not a customer quote

Convenient scheduling. Positive reviews say the installation was scheduled around the customer’s availability and handled efficiently. Representative review excerpt: "The installation was scheduled and coordinated with us to our convenience and challenging schedules."

Fast installation in some cases. A number of reviewers describe the installation as quick, even on more complicated properties. Representative review excerpt: "Installation was amazingly fast considering the required effort to install on a 2-story building with a tile roof to an older electrical panel."

Permit and inspection delays. Complaints describe projects taking months longer than expected or not reaching final inspection in a timely way. Representative review excerpt: "Original review: KOTA and its sales representative commenced our solar project in 2020 and though the equipment was installed in early 2021 it has not passed final inspection with the..."

Workmanship & site care

Workmanship6.5/10

Reviewers often describe the crew as professional, prompt, and capable of handling complex roofs or careful panel placement. Even so, some complaints mention roof damage, broken tiles, or disputes over whether installation-related repairs were properly handled.Solar.com's composite of published customer feedback, not a customer quote

Professional crews. Positive reviews commonly mention prompt, professional installers who answered questions and worked carefully on site. Representative review excerpt: "He answered all of our questions and the install crew was prompt and professional."

Careful design and appearance. Some customers say the system was designed neatly and installed in a way that blended well with the home. Representative review excerpt: "Also, the panels themselves are sleek and installed in such a way that from the street you can hardly even tell we have them."

Roof damage complaints. Complaints describe broken tiles, leaks, or repair disputes after the installation work was completed. Representative review excerpt: "Paid over $20k for solar panels, only to find out their poor installation caused roof damage and a roof leak."

Long-term support & performance

Long-Term Support6.5/10

Post-install feedback is fairly balanced. Many reviewers report systems working well and say they received helpful support with monitoring, billing, or inverter questions, but others describe unresolved service issues and warranty follow-up that stalled.Solar.com's composite of published customer feedback, not a customer quote

System working well. Several reviewers say the system has been operating properly after installation. Representative review excerpt: "The system was installed and is working very well."

Helpful post-install support. Some customers report that the team explained bills, app usage, or inverter concerns in a helpful and professional way. Representative review excerpt: "I contacted them regarding an inverter thats was not working properly, I got in contact with Tripper Gawan VP and he was very attentative,helpful,kind and very professional!"

Warranty and repair complaints. Complaints describe trouble getting repair follow-up or warranty support after the system was up and running. Representative review excerpt: "Attempted to allow Kota to fix the issue and follow through with their written contract and warranty but they now have stonewalled us."

Bottom line: KOTA CONSTRUCTION’s review profile is mixed, with stronger marks for sales guidance and installation quality than for pricing clarity, communication, and timeline reliability. Reviewers commonly praise professional crews and helpful explanations, but a meaningful number report delays, billing disputes, and unresolved follow-up 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.
