Del Sol Energy reviews

The Verdict
Del Sol Energy is a safe choice if you want a local installer who won't ghost you after the sale. We analyzed over a hundred reviews and found a company that handles the basics well, installs panels without obvious mistakes, and shows up years later when something breaks. One homeowner noticed an inverter failure in 2019, and Del Sol swapped the entire unit at their own expense rather than pointing him toward the manufacturer's warranty department. Another customer went four years without a true-up bill because the company right-sized the system from the start. The most distinctive pattern we noticed is how often reviewers mentioned painted conduit, a detail that sounds trivial until you realize it means the crew didn't treat your roof like a construction site. We also saw 80 mentions of workmanship quality with zero complaints about leaks or damage. The downside? A handful of customers reported waiting months for help when their systems went offline. One couple paid PG&E for four months before Del Sol diagnosed a faulty communication board. If you need hand-holding through monitoring dashboards or immediate callbacks, you may feel neglected. But if you want a straightforward install and are willing to chase them down when issues arise, Del Sol delivers on the fundamentals.
If you can tolerate occasional slow callbacks and you prioritize local presence over white-glove support, Del Sol is a reasonable pick. You won't get the most responsive service team, but you will get a crew that paints conduit to match your house and fixes inverters at their own cost.
Reviews That Shaped Our Verdict
Julie C. discovered last year that her solar array had gone offline for several months without the installer notifying her. In November she opened the true-up and nearly fainted — the bill topped $1,800 — after PG&E’s production data showed the system produced virtually no energy for roughly four winter months. She spent weeks calling Del Sol, asking them to investigate, and dug through her PG&E statements with a fine-tooth comb; she uncovered multiple anomalies in the energy records that point to something wrong with the system. Julie has had the system since 2016 and always ended up with a credit on her true-up until this year, so the sudden outage and the unexpected charge felt especially troubling given how much she paid for the installation. Del Sol has not responded to her requests for help, and she’s left wanting a clear explanation of the four-month outage and who will take responsibility for the $1,800 true-up.
Samuel V., an engineer and financier with years in the solar industry, did extensive research and interviewed five installers before choosing Del Sol for a residential system because they answered his technical questions, kept pricing competitive, and presented a straightforward approach. He watched the crew install the array professionally; they ran conduit neatly, took the extra step to paint it to match the house, and left the site tidy. Soon after the system went live he noticed recurring inverter problems, and when the original manufacturer's slow timeline threatened a long outage, Del Sol stepped up: they absorbed the cost and swapped in an inverter from a different manufacturer to get the system back to full operation. He came away most struck by their willingness to take responsibility for a critical component rather than force the customer to battle the manufacturer — paired with the clean, careful installation details, that was what set the experience apart.
When shopping for a rooftop system in spring of 2019, Gayle N. discovered Del Sol quoted several thousand dollars less than Sunrun and specified higher-end gear — LG panels with Enphase microinverters. She appreciated that Del Sol laid out which financing choices would save the most money, and that all permits and approvals arrived on the timeline the company had promised. Installation went quickly and neatly: conduits were painted to match, the site stayed tidy, and the crew left no loose ends. Owner Josh Aldrich stepped in when the system needed to be reconnected to Enphase and handled it promptly. A memorable touch: when Josh gave a large bonus to a relative, Gayle received an equivalent discount on her job. More than four years after the spring 2019 install she still hasn’t received a True-Up bill, and she’s pleased the system was right-sized and uses panels expected to degrade more slowly than many older installations. The detail that lingers is that personal, hands-on follow-up and the matching discount — plus the absence of any True-Up charge years later.

Craig chose Del Sol to install a rooftop solar system, and the crew finished the work on schedule with solid engineering behind the design. Four years after activation he hasn’t owed a true-up; in summer months the system often produces enough excess that his bill sits at zero for several consecutive months. Beyond the numbers, Del Sol took the extra step of painting the conduit to match the roof and siding, so the installation reads as sleek panels on the roof rather than exposed galvanized pipe. He ended up with a tidy, high-performing system where the painted conduit is the detail that most separates this job from a typical install.
Jay hesitated to go solar at first and wanted a local, long-standing company he could call with questions before committing. He chose Del Sol in 2019 and invested in a 30-panel LG array, having researched panels and inverters and sizing the system to about a 104% offset based on the previous year’s usage. Fai Murphy guided him through the options, followed up repeatedly with details, and her crew installed the panels in a few hours; they returned the next day to paint the conduit and add bird netting after running short of material and ordering more. An electrician friend inspected the work and praised the installation quality. When true-up arrived it was actually a credit of $56, and because he claimed the full 30% federal tax credit on that year’s return (after adjusting his taxes) he didn’t lose any of it. He chose not to apply the tax credit toward the solar loan, and overall his out-of-pocket position is about $60 a month better than what he was paying PG&E. Del Sol also sent $500 to his kids’ school after the purchase, which stood out as a meaningful community gesture. He uses the system app daily to track production and checks PG&E’s site to see imports and exports; he’s eye
