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

How does Luminalt Energy 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 Luminalt Energy 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.

Luminalt Energy 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 clear, helpful sales conversations and proposals, with many saying the team answered questions thoroughly and explained the process well. A small number of complaints mention expectations around agreement fulfillment and project follow-through, so the overall read is positive but not flawless.Solar.com's composite of published customer feedback, not a customer quote

Clear, responsive quoting. Reviewers frequently say Luminalt replied promptly, answered contract questions, and explained proposals in a way that felt knowledgeable and straightforward. Representative review excerpt: "We messaged several solar installers for quotes, and Luminalt was prompt in their reply, as well as honest, and very knowledgeable."

Helpful through the decision process. Several customers describe the team as open, honest, and willing to walk through changes to the original plan without pressure. Representative review excerpt: "Luminalt was not only able to remove the battery from the original quote, install panels and inverter in just a few days, but explained the process throughout the project in..."

Agreement follow-through concern. A small number of reviewers report frustration that work they believed had been agreed to was not completed as expected. Representative review excerpt: "Trying to get work done since September 2024 and now they decided they don't want to do it even though they made the agreement."

Price & financing transparency

Price Transparency7.0/10

Feedback on pricing and financing is mixed-to-positive. Reviewers often say costs were explained clearly and financing terms were understandable, but a few comments raise concerns about price level, deposits, or the way expectations were handled.Solar.com's composite of published customer feedback, not a customer quote

Financing and cost walkthroughs. Some reviewers say the company explained costs, usage, and savings carefully, including financing details and project scope before work began. Representative review excerpt: "They set up a zoom call where they went through everything that their service provided, how the installation would work, costs and overall usage and savings with solar."

Clear but not always inexpensive. A few customers note that Luminalt can be pricier than some quoted options, while still describing the service and materials as worthwhile. Representative review excerpt: "Luminat is a bit more expensive than some other options, but they use high quality (Sun Run) panels, their customer service is so far wonderful, the entire project took 4..."

Watch-outs on expectations and timing. A small number of reviewers describe dissatisfaction tied to agreement handling or money-related expectations, including one report of a zero-down financed project that felt manageable month to month. Representative review excerpt: "We financed the installation zero-down, and our monthly payments are roughly the same as our pre-solar electric bill, so it feels like it didn't cost us anything."

Communication & coordination

Communication8.4/10

Reviewers generally describe strong coordination and responsive support, especially during planning, permitting, and issue resolution. The main complaints are isolated and focus on delayed replies, schedule changes, or incomplete follow-up when something needed attention.Solar.com's composite of published customer feedback, not a customer quote

Responsive and knowledgeable team. Many reviewers say the team answered questions promptly, stayed professional, and took ownership of details across the project. Representative review excerpt: "I had a ton of questions related to the contract and install and everyone with whom I interacted was super friendly, knowledgeable and excited about solar!"

Good coordination through permitting. Some customers specifically mention smooth handoffs and familiarity with city processes, which they felt helped projects move along efficiently. Representative review excerpt: "The team is extremely knowledgeable, they have done hundreds of successful installs in SF and know the permitting process and the building department inspectors personally to get things done quickly."

Follow-up gaps in a few cases. A few reviewers report slow or incomplete follow-up when problems came up, including situations where they wanted clearer updates or repair progress. Representative review excerpt: "So far, I've received a few emails in return, expressing regret, but no repairs, no update, and no reassurance that they will ever fix the problem with the system that..."

Timeline reliability

Timeline Reliability7.6/10

Most reviewers describe projects moving on schedule or reaching PTO in a reasonable timeframe, with several praising efficient permitting and inspection handling. There are a few complaints about delays or missed commitments, so timeline performance appears generally solid but not perfect.Solar.com's composite of published customer feedback, not a customer quote

Efficient path to PTO. Several reviewers say the project moved from contract to permission to operate in a fairly short timeframe and that the permitting process felt well managed. Representative review excerpt: "The entire project took just 3 months from my initial March contact to June Permission to Operate (PTO)."

On-time install and inspection flow. Some customers report that installation happened on the date promised and that follow-up inspections came sooner than expected. Representative review excerpt: "Waiting for city inspections is never fun, but was amazed that Luminalt's schedule hit the install date exactly, they got the job quickly, and follow up inspections happened sooner than..."

Occasional delay complaints. A small number of reviewers describe longer-than-expected waits or missed commitments, especially when schedules changed after work had already been agreed. Representative review excerpt: "Trying to get work done since September 2024 and now they decided they don't want to do it even though they made the agreement."

Workmanship & site care

Workmanship8.9/10

Reviews are strongly positive on installation quality and crew professionalism. Customers frequently describe careful, efficient work and courteous crews, while complaints about workmanship or site care are rare in the corpus provided.Solar.com's composite of published customer feedback, not a customer quote

Strong install quality. Reviewers often praise the installation itself, including solar, battery, and related electrical work, as clean and well executed. Representative review excerpt: "10/10 Luminalt was great to work with for installing solar panels on the pitched roof of our home and battery storage in our garage!"

Professional crews. Customers mention installers by name and describe them as excellent, courteous, and efficient on site. Representative review excerpt: "Cody and Fabian did an excellent job with the installation!"

Rare workmanship issue. One review raises concern about a system-data problem, which is more of a post-install service issue than a broad pattern of install complaints. Representative review excerpt: "Only to be followed by my finding that our solar generation and power usage had been wrong for 2 years so the app data was useless."

Long-term support & performance

Long-Term Support8.8/10

Post-install feedback is mostly favorable, with reviewers describing responsive warranty help, repair visits, and prompt troubleshooting after the system was up and running. A few reviews raise concerns about performance expectations, repair follow-up, or added battery cost, but those complaints are not the dominant pattern.Solar.com's composite of published customer feedback, not a customer quote

Responsive service after turn-on. Several reviewers say the team replied quickly when issues came up and helped resolve repair or service needs without much hassle. Representative review excerpt: "If we ever have any issues we email her and she always replies promptly, professionally and always goes above and beyond to solve any and every issue we have!"

Helpful repair visits. Customers also report that the company returned to diagnose and fix post-install electrical or inverter issues when needed. Representative review excerpt: "The inverter started issuing 'electric arc fault' messages about a year ago throwing the system off line.They were able to correct it at the time."

Performance and support watch-out. A small number of reviewers describe concerns about reliability, unresolved follow-up, or battery-related cost and outage expectations. Representative review excerpt: "However, the battery system adds $$$ to the overall cost (nearly doubled our quote), and from what I understand, the battery won't be charging during the power outage unless you..."

Bottom line: Luminalt Energy’s reviews are generally positive, with especially strong feedback on installation quality, communication, and post-install support. The most consistent caution points are price transparency, occasional scheduling friction, and a small number of complaints about follow-through on specific issues.

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.
