How does "Infinium Solar, Inc." 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.

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.

"Infinium Solar, Inc." 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 Integrity7.3/10

Reviewers most often describe the sales process as clear and low-pressure, with several saying proposals, design, and permit guidance were handled well. A small number of complaints point to delays in receiving quote details or confusion about what was included in the original scope.Solar.com's composite of published customer feedback, not a customer quote

Clear, consultative sales approach. Many reviewers say the sales experience felt straightforward and informative, with expectations explained up front and no hard pressure to proceed. Several also credit the team with helping design the system and navigate permit steps. Representative review excerpt: "Infinium Solar did an AMAZING job designing the layout, getting permits, ensuring everything is installed and setup correctly to make our home fully independent of the grid."

Low-pressure interactions. Some customers specifically note that the team did not push them into decisions when timing or repair needs were uncertain. That kind of pacing is part of the stronger feedback in this category. Representative review excerpt: "They told me upfront that the repair might not be completed before year-end, but they understood the financial burden I was facing with my system down and never pressured me..."

Occasional scope and quote friction. A smaller set of reviewers report delays or misunderstandings around what was included in the proposal, including waiting for project details or learning that additional planning work would be needed. These complaints are limited but point to occasional gaps in early-stage clarity. Representative review excerpt: "Instead of moving forward with the project, Infinium indicated that in order to draw up plans, which I had assumed were already part of the package, and draw up a..."

Price & financing transparency

Price Transparency6.6/10

At the same time, a noticeable minority report confusion around billing, change orders, deposits, or other pricing details, so this category reads as positive-to-mixed rather than uniformly strong.Solar.com's composite of published customer feedback, not a customer quote

Pricing pricing for many projects. Some also mention successful code upgrades and added battery work without major pricing surprises. Representative review excerpt: "Their communication was clear, their price was competitive, and they worked seamlessly with SMUD (and PG&E for others) to ensure everything was permitted and running smoothly."

Post-install savings cited. A number of customers report noticeably lower monthly electric bills after the system was running. Those savings are a recurring theme in the stronger reviews tied to this category. Representative review excerpt: "Our system has been up and running for a few months now and our electric bills have dropped from $500-$600 a month down to $16 a month."

Some billing and pricing confusion. Complaints focus on unclear change-order expectations, incorrect billing, and delays in getting pricing updates when scope changed. Reviewers also mention cases where they had to follow up repeatedly to understand the final price. Representative review excerpt: "There were repeated examples of internal miscommunication: * Incorrect anchor information * Wrong anchors installed * Incorrect billing * Conflicting instructions from different teams I frequently had to identify problems..."

Communication & coordination

Communication7.5/10

Communication is one of the company’s stronger areas, with many reviewers praising responsive staff and steady project management. The main complaints involve missed updates, slow follow-through on pricing adjustments, and occasional no-shows or long delays when coordination broke down.Solar.com's composite of published customer feedback, not a customer quote

Responsive project management. Many reviewers say staff stayed available, answered questions, and kept the project moving. Several note that the team handled city coordination and follow-through well. Representative review excerpt: "They handled all the heavy lifting with the city, seamlessly managing the plan design reviews and following through until everything was officially signed off."

Helpful updates through the process. Customers often describe receiving regular updates and feeling informed about next steps. That ongoing contact appears to be a common positive thread in the feedback. Representative review excerpt: "We were never in the dark as to what the next step was."

Occasional follow-up and scheduling gaps. Some reviewers report having to chase the company for pricing updates, and others describe missed appointments or long stretches without clear contact. These issues are not the dominant pattern, but they do show up often enough to matter. Representative review excerpt: "There was supposed to be a $100/mount deduction because my roofer handled the mounting and waterproofing, but I had to repeatedly follow up before receiving updated pricing."

Timeline reliability

Timeline Reliability6.9/10

Reviews lean positive on schedule management, permit handling, and final activation, but there are enough delay complaints to keep this category near the mixed line. Several customers praise smooth permitting and clear progress updates, while others describe gaps between approval and installation or slower-than-expected completion.Solar.com's composite of published customer feedback, not a customer quote

Smooth permit and inspection handling. Many reviewers say the team managed permits, inspections, and sign-off without forcing them to coordinate the details themselves. Those experiences are a key reason the category trends positive overall. Representative review excerpt: "They kept us in the loop through every phase--from the initial design and scheduling to installation and the final inspection."

Clear next-step communication. Some customers say they always knew what was happening next and were not left guessing about the project timeline. That kind of process visibility shows up repeatedly in the stronger reviews. Representative review excerpt: "We were never in the dark as to what the next step was."

Delays between approvals and install. Complaints focus on long gaps after permit approval, rescheduling issues, and slower progress when outside approvals or inspections were involved. Reviewers describe these delays as frustrating even when the work itself was eventually completed. Representative review excerpt: "However, there was a five-week gap between permit approval and panel installation, even though the installation itself only took one day."

Workmanship & site care

Workmanship7.5/10

Most reviewers describe the crews as careful, professional, and thorough, with strong marks for installation quality and cleanup. The main complaints are isolated but notable, centering on roof damage, inspection-related issues, and a few cases of slow or uneven reinstall work.Solar.com's composite of published customer feedback, not a customer quote

Meticulous installation work. Reviewers frequently praise the crew’s attention to detail, including battery, conduit, and panel work. Several say the installation looked organized and professionally executed. Representative review excerpt: "I'd like to give a shout out to Juan, Ernesto, and crew for the meticulous installation of batteries, conduits and panels, Ryan and Edgar who made several site visits to..."

Handles complex site conditions. Some customers say the company managed added complexity well, including electrical upgrades and roof-related reinstallation. That flexibility is part of the stronger workmanship feedback. Representative review excerpt: "Infinum also accommodated take-down and re-install of the solar panels as we were replacing the roof (it added to complexity of the project)."

A few damage and quality complaints. A smaller set of reviewers report roof damage, shoddy work, or reinstall projects that took far longer than expected. These complaints are not the majority, but they do suggest occasional site-care and finish-quality concerns. Representative review excerpt: "The installation team also damaged our roof during installation, requiring my roofer to repair the roof membrane afterward."

Long-term support & performance

Long-Term Support7.1/10

Post-install support is generally viewed positively, especially when customers needed help with system issues, monitoring, or warranty-related questions. Still, some reviewers report performance setbacks after service work or unresolved warranty concerns, so the category is positive overall but not spotless.Solar.com's composite of published customer feedback, not a customer quote

Supportive follow-up after installation. Many reviewers say the team stayed responsive after the system was turned on and helped work through questions or issues. Some also mention successful support with upgrades and troubleshooting. Representative review excerpt: "They worked hard to find solutions to all of these issues and difficulties, and they have an amazing supportive team that kept the project moving quickly and efficiently."

Generally strong long-term system results. Several customers report that their systems worked well over time, including examples of reliable production for years. Those reviews suggest solid long-term performance for a large share of projects. Representative review excerpt: "We used Infinium Solar services before to install a 5KwH Solar system in our home, which worked flawlessly for many years."

Some unresolved warranty and performance issues. Complaints include failed inverters, support that did not fully resolve a warranty problem, and a few cases where post-service performance dropped or other follow-up work was still needed. These reports keep this category from reading as purely strong. Representative review excerpt: "A simple removal and reinstall of a solar system took them 5 months and the output of the system dropped 50% after they reinstalled it."

Bottom line: Infinium Solar, Inc. holds a solid overall review profile, with strongest feedback around communication, workmanship, and the sales experience. The most common complaints center on pricing clarity, timeline delays, and occasional post-install follow-up issues, but those concerns appear less frequent than the praise across the review set.

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.
