Longhorn Solar reviews

Ray chose Longhorn for a seven-year-old rooftop system because they offered competitive pricing and a solid, established track record — not a fly-by-night installer. Over those seven years he experienced an inverter failure and, more recently, a Tesla battery problem; both times the parts and labor fell squarely under warranty and were replaced. He noticed delays between reporting outages and repairs, but chalked that up to the realities of ordering replacement parts and scheduling installations rather than any lack of effort on Longhorn’s part. The consistently distinctive part of his experience has been the people: every technician who visited and the Longhorn tech he deals with by email, Luke, proved knowledgeable, friendly, and patient in explaining what was happening. He also made a point of saying he’s not receiving any discount or perk for this praise—he’s simply impressed. When a later glitch cropped up in the Tesla gateway’s communication with the solar array and batteries, Longhorn sent someone out the following week and the system has been working perfectly since.

M Danielian has relied on Longhorn for more than five years to keep their home’s solar system running smoothly, and the through-line across that time has been responsiveness and follow-through. What started with Jameson in sales became a multi-step, collaborative process: Jameson listened to wants and needs, went back and revised proposals a couple of times, and pushed until the fit felt right. David, the field supervisor, stepped in to oversee installation details and kept tightening loose ends on-site, while Jared from service showed up afterward to verify the system was operating properly. Over the years they’ve called Longhorn for support and consistently found the company ready to help—answers, repairs, and checks happen without long waits. The most memorable part of the experience was the team handoff—sales, field, and service all owning their piece—so the final sign-off from Jared felt like the proof of their pride in the work.

Tim had a 2.5-year-old solar system when one panel suddenly stopped working — the first problem he’d seen since installation. Longhorn Solar sent a technician, Adam, who replaced a failed optimizer and brought the system back to 100% production. He described Adam as professional and friendly; Adam walked him through the repair so he understood exactly what was done. The repair was covered under warranty, and the clear, no-cost optimizer swap — plus the technician’s explanation — is the detail that stuck with him.

A decade ago Michael hired Longhorn Solar to outfit his home with solar panels. The array has weathered rain, hail, and snow and still runs reliably. Service didn't end at the install — whenever a question or a small issue popped up over the years he reached out and Longhorn responded promptly and helpfully. The standout detail: after ten years of varied weather the system keeps performing, and the company has stayed a quick, practical resource for any follow-up needs.

Fpo bought a 36-panel solar array with a 10 kWh LG battery for their ranch-style home in November 2018 — an about $55,000 installation — and has lived with the system for nearly seven years. What stands out most is how Longhorn Solar stuck with the job: whenever something went wrong their crew showed up and fixed or upgraded parts without charging extra, and they pushed the manufacturer hard until a warranty replacement arrived. The array has produced reliably on sunny days, but the ride hasn’t been without hiccups. Fpo encountered two blown fuses that Longhorn repaired, had the inverter replaced twice, and had an automatic shut-off relay added to the system at no cost. The LG battery failed twice and Longhorn fought for five months to get a replacement; the third battery was eventually approved and installed for free. Fpo believes the problems came down to battery programming. The first LG unit repeatedly emptied overnight and then recharged fully on sunny days, yet still lasted about 4.5 years. The second unit was set to stay at 100% and only lasted around two years. The newly installed third battery comes with a smarter program that keeps its state of charge around 20–50% in

Tommy K had a residential solar array installed in 2018 and, when his roof was replaced in 2020, his insurer had Longhorn Solar remove and reinstall the panels. After the reinstallation he discovered generation had plunged to less than half of its previous output. He spent weeks badgering the company with calls that went to voicemail and unanswered emails; only after copying the CEO did technicians finally show up, and those techs tried to pin the loss on animals. The same drop in performance cropped up again in 2024, and once more the company ignored his calls and messages. He regrets choosing them, and the detail that sticks is this: the only way he got anyone to act was by escalating directly to the CEO.

Marty has relied on Longhorn Solar for a PV system for 12 years, and throughout that time the company repeatedly stepped in to keep the array running perfectly. He watched them go above and beyond on service and maintenance rather than disappearing after installation. After a decade-plus of hands-on support and trouble-free performance, he recommends Longhorn to anyone considering a PV system — the standout is their long-term, proactive care that preserved the system’s operation for years.

Richard had spent three and a half years with a solar system that kept malfunctioning. A pair of technicians showed up to diagnose the issue and, after their inspection, he finally understood what had been wrong all along. He found their work fantastic and felt relieved that, although it took far too long, the system’s problems now have a clear path to being fixed. The memorable takeaway: after 3½ years of uncertainty, the crew actually pinpointed the fault.

Ray Hassen hired the company to detach and re-attach his solar panels while his roof was replaced. He discovered the crew had subcontracted the job to inexperienced contractors, and the finished work showed poor quality and weak supervision. When problems surfaced, the company stopped returning his calls for service and warranty support. Even after being left without timely help, he kept getting outreach from the company offering a referral reward to find new customers — a tone-deaf move that underscored the disconnect between their sales efforts and aftercare. The most memorable detail for him was that persistent reward pitch in the face of unresolved warranty issues, a mismatch that any prospective buyer should weigh heavily.
