Prime SLR puts panels on roofs, then disappears. We found 10 reviewers whose systems were installed but never turned on, some waiting months or even years for the city inspection or the battery they paid for, all while making loan payments on equipment they can't use. One customer waited from April to October for a fix that Prime quoted at $3,000, work that should have been done right the first time. Another signed in November 2024, got panels in January, was promised batteries in April, and by July the owner stopped answering entirely. The pattern is consistent: quick installation followed by radio silence. We noticed 20 separate complaints about post-sale support, most describing ignored calls, full voicemail boxes, and unanswered emails. (One reviewer suspects the ghosting is strategic, forcing customers to hire another installer and void their warranty.) Meanwhile, 19 reviews mention problems that needed fixing after install, from failed inspections requiring master electricians to breakers that knocked the whole system offline. Mustafa, the owner, is often the only contact, and when he goes dark, your panels just sit there generating power you can't use or debt you can't escape.
If you want solar panels that actually produce power you can use, skip Prime SLR. The installation might be fast, but the odds of getting stuck in limbo with an unfinished system and an owner who won't return your calls are too high to risk your money.
Sterling had Prime Solar put rooftop panels on his house in September; the actual installation went up quickly, but the months that followed turned into an ongoing slog. He watched scheduling snafus and missed steps pile up: Prime’s rep Mustafa kept insisting “we have you scheduled,” yet the company hadn’t actually booked the city inspection. The first city visit failed after an inspector showed up two hours early. The second appointment never happened because Lewisville doesn’t do Friday afternoon inspections. A third attempt failed when Prime sent a regular employee despite explicit instructions that a master electrician was required. A fourth visit finally brought a master electrician — who hadn’t brought the right tools and had to buy one on-site before repairs could be completed. After that hurdle cleared, a new DG meter from TNMP became the next roadblock. TNMP told Prime in mid-November they needed photos of the entire meter unit, not just roof panels; Mustafa knew this but didn’t act until Sterling called TNMP in December. Meanwhile the solar loan payments kicked in in December for a system Sterling couldn’t use, and he kept receiving utility bills. Mustafa promised to “re
Eric De La Rosa signed a contract in November 2024 for a 10 kW solar system with a backup battery for his home. After repeated excuses the panels finally went up in January 2025, but the company blamed a battery backorder and pushed the backup install out to April. By late July 2025 communication collapsed: owner Mustafa stopped answering calls, texts and emails. The last message from Mustafa, sent the month before, claimed the batteries had arrived and only scheduling remained, yet no follow-up or installation materialized. Frustrated with a partial system and no clear timeline, he is now exploring legal options to force completion of the work he paid for.
When Derek Maxwell signed with Prime Solar he expected the full package the sales pitch promised. Instead he discovered that, more than five months after the panels were installed, the promised batteries never arrived and the expected energy offset never materialized. He’s been exporting power back to the grid without receiving credit because the system can’t be adjusted until the battery portion is completed. Attempts to get answers turned up empty — calls and emails went unanswered, and even reaching out directly to owner Mustafa produced no response. Frustrated, he has consulted a Dallas-based attorney who handles solar contract disputes and says he will shut down the system and pursue contract dissolution if Prime Solar doesn’t follow up. The detail that will matter to other buyers: months after installation the core add-on that enabled the savings — the batteries and the billing adjustments tied to them — hadn’t been delivered, and communication from the company broke down entirely.

Todd Trueblood hired Mustafa and his team to install a home solar system and found their work excellent from the first call to the final details. He connected with Mustafa on three separate occasions and discovered the team to be consistently responsive and thorough each time. Mustafa went beyond installation, recommending a specific battery-backup option that would pair well with the system, so Todd walked away with both the panels in place and a clear, practical path for adding backup power. What lingered for him was the steady responsiveness and the concrete battery recommendation — not a vague upsell, but a usable next step.
Doug had panels installed by Prime Slr three years ago and discovered recently that a breaker fault left the array completely offline — so his system stopped producing and he began losing money. He found that the company's only listed contact was the CEO, but every call routed straight to voicemail and the mailbox was always full, so he couldn't even leave a message. Emails and texts went unanswered, and every attempt to get a technician on site hit a wall. He grew worried that Prime Slr might be forcing customers to hire outside installers to troubleshoot, which could let the company later claim any warranty is voided because another contractor intervened. The most striking detail in his experience was the lack of any reachable support — a full voicemail box that prevented lodging a complaint — leaving him with a nonworking system and no clear path to make a warranty claim.
Silvia had solar panels installed on her home in January 2023 but discovered they were never connected. She tried calling the company repeatedly and found them unresponsive. She also learned the installer arranged bank financing for the system even though she never signed any paperwork. The lasting image is stark: panels sitting on the roof since January, unpowered, while financing appears to have been initiated without her consent.
Waldo Silva had Prime SLR install his solar panels just over a year ago. He appreciated that the installation crew walked him through every step, answered all his questions during the process, and made sure he understood the installation. The team worked quickly and cleaned up completely, leaving the site tidy when they finished. A year later he still highlights their clear explanations and thorough cleanup as the details that mattered most.
Valerie has had a rooftop solar array for nearly two years and remains pleased with how it’s performed. When she needed a roof replacement, she called the same company back; they removed the panels so the roofers could work and then reinstalled the system afterward, scheduling the work around her availability. The easy coordination and willingness to be flexible during the roof project is what stuck with her and reinforced her choice.
Larry R had solar panels installed in June 2025 and was told the battery units would follow. He handed cashier's checks to the installers, then waited — calls went unanswered and no batteries arrived. When he pushed the company for an update, they insisted he had not made a down payment. Frustrated by the mismatch between the payment he gave to installers and the company's denial, he is talking with others about forming a class-action lawsuit. The image that sticks: panels up on the roof, promised batteries missing, and no company confirmation of the funds he paid to the crew.
Marjie discovered a string of solar panels that had stopped working. On a cold, windy day Abdullah came out, traced the problem and repaired the faulty string on the spot. She watched him work professionally and efficiently, and the system was back in order by the end of the visit. The detail that sticks is that he showed up despite the weather and resolved the issue quickly.
