How does 1St Light 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 1St Light 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.

1St Light 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 Integrity4.7/10

Reviewers give mixed feedback on the sales experience. Some describe helpful, honest, and informative representatives, while others say the proposal stage set expectations that did not match the outcome on savings, equipment, or follow-through.Solar.com's composite of published customer feedback, not a customer quote

Expectation gaps after sale. Other reviewers report that the system did not perform as promised or that key expectations were not met after signing. These comments include concerns about promised savings and post-sale service. Representative review excerpt: "They sold me solar 10 years ago with the promise of no more PG&E bill."

Good-faith follow-up on a rocky start. A smaller set of reviews says the company worked to rework a project and communicated more openly after problems surfaced. That suggests some customers did see effort to correct earlier issues. Representative review excerpt: "And while our project started out rocky, we're grateful to 1st Light Energy for making good on their business promise, reworking our system, and being open and honest once we..."

Helpful, clear consultations. Several reviewers say the sales team was informative, honest, and easy to work with during the initial consultation. A few also describe the process as clear and low-pressure. Representative review excerpt: "Kyle was informative and efficient while inspecting our property for future solar needs."

Price & financing transparency

Price Transparency4.0/10

Feedback on pricing and financing is mostly negative. Reviewers describe confusion around lease terms, interest, fees, and add-on costs, though a few say the financing process was explained clearly.Solar.com's composite of published customer feedback, not a customer quote

Unexpected costs and lease confusion. Many reviewers report surprise charges, unclear lease terms, or trouble understanding how financing would work over time. Some also mention fees or costs tied to repairs, payoffs, or moving the system. Representative review excerpt: "excessive fees and lack of accountability."

Incentive timing noted in a mixed review. One reviewer says the financing options were not ideal but did not end up mattering in their situation. This reads as a limited positive rather than a broad endorsement. Representative review excerpt: "I wasn't wild about the financing options they offered, but we refinanced our house so it didn't really matter."

Financing explained clearly for some. These customers describe the process as understandable and more manageable than they expected. Representative review excerpt: "The salesman (Cade Spackman) was very specific in explaining our options to purchase or lease the system and the financing process as well."

Communication & coordination

Communication3.6/10

Communication is a major pain point in the review set. While some customers describe clear updates and responsive staff, many others say they had trouble getting callbacks, status updates, or ownership once the sale was complete.Solar.com's composite of published customer feedback, not a customer quote

Slow or absent responses after the sale. Many reviewers report that communication dropped off after the initial sale. They describe repeated attempts to reach the company, with limited follow-through on questions or service needs. Representative review excerpt: "If you’re looking for a company that doesn’t respond to their customers beyond the initial sale, then proceed with 1st light energy."

Some coordination help during installation. A smaller set of reviews mentions proactive coordination, such as moving up an installation date or helping customers understand next steps. These comments suggest occasional strong service, but not consistently. Representative review excerpt: "He called a month prior to my appointment for installation because he had a cancellation and I was able to get them installed the same day!"

Clear communication for some customers. A handful of reviewers say they were kept informed and felt supported through the project. These accounts describe the team as responsive and easy to reach. Representative review excerpt: "Had clear communication throughout the entire process."

Timeline reliability

Timeline Reliability4.8/10

Timeline feedback is mixed to negative. Some reviewers say delays were tied to permits or inspections, but many others report long waits for responses, repairs, or completion of the project.Solar.com's composite of published customer feedback, not a customer quote

Long waits for service and responses. Many reviewers report months-long delays in getting calls returned, parts ordered, or service scheduled. Some say the delay extended far beyond the original timeline they were given. Representative review excerpt: "Inverter died - took months just to get someone on the phone to get a new one ordered."

Delays tied to permits and inspections. A few reviewers say the waiting period was driven by permit and inspection timelines rather than the company’s direct actions. These comments frame the delay as part of the process rather than a project failure. Representative review excerpt: "All of the wait time that we experienced was due to waiting for permits and inspections, which is not the fault of 1st Light Energy."

Some installs finished on schedule. A smaller group says installation went smoothly and on time, with no major issues afterward. These reviews indicate that schedule performance was not uniformly poor across all projects. Representative review excerpt: "I am very satisfied with the timeline of my installation and have not had any problems with my system!"

Workmanship & site care

Workmanship4.7/10

Workmanship feedback is uneven. Some customers say crews were efficient, careful, and kept the work area clean, while others describe roof damage, awkward installations, or repair follow-up that did not resolve the issue quickly.Solar.com's composite of published customer feedback, not a customer quote

Roof and repair concerns. Other reviewers report damage, awkward panel placement, or post-install problems that were not handled to their satisfaction. Some also say repair support was slow or incomplete. Representative review excerpt: "the solar installation has ruined a huge portion of our roof and included interior damage to multiple rooms- their response, we will give you 10% off of your solar panel..."

Clean, efficient crews. Several reviewers say the installation crew worked quickly and kept the site tidy. These customers describe a professional in-person experience during the install itself. Representative review excerpt: "The crew knew what they were doing and finished quickly."

Cleanup praised in some projects. A few reviews specifically mention that the crew kept the area clean and reduced follow-up headaches. That suggests site care can be strong even when the broader project experience is mixed. Representative review excerpt: "Kept the area they work clean at all times."

Long-term support & performance

Long-Term Support4.9/10

Post-install support and performance draw a mix of appreciation and frustration. Some reviewers report good system output and helpful fault resolution, but many others say warranty help, inverter repairs, or other service issues took too long or were not resolved well.Solar.com's composite of published customer feedback, not a customer quote

Service and warranty frustrations. Many reviewers say post-install service was difficult to get, especially when equipment failed or warranty questions came up. They describe slow help, limited follow-through, or concerns that support did not match expectations. Representative review excerpt: "This is not the integrity or support customers expect from a company promoting "

Some systems performing well. A number of reviewers say their systems are producing as expected and that they remain satisfied months or years after installation. These comments suggest some customers do see reliable long-term performance. Representative review excerpt: "I've had my system for 7 months and am very happy thus far."

Some inverter issues resolved. A smaller set of reviews says the company did help diagnose or resolve inverter problems after installation. These accounts show that some service interactions were productive, even though they were not the norm. Representative review excerpt: "Found and resolved my Inverter fault."

Bottom line: Reviewers give 1ST LIGHT ENERGY a mixed overall picture, with some positive notes on helpful staff, clean installs, and occasional follow-through. But the strongest patterns across the review set are weak communication, pricing and financing confusion, and delays or difficulties after the system is installed.

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.
