Kosmos Solar reviews

Franx4ever invited Kosmos to their home in 2017, when solar still felt new to the household, and Kevin walked them through the technology until they felt comfortable moving forward. The installation went smoothly and the panels have since trimmed their electric bills. Over the years they ran into a couple of real-world problems — squirrels chewed through wiring and a few panels stopped working — but Kosmos dispatched a technician quickly and repaired everything. Customer service stayed responsive, and that fast, practical support — especially the prompt fix for wildlife damage — left them confident Kosmos will continue to stand behind the system as other installers disappear.

Brenda F. signed a contract with Kosmos Solar on 11/20/20 after a very positive sales interaction with Parry, but she ended up frustrated by recurring equipment failures and poor follow-up. The installer began work 1/12/21 and completed the job on 1/13/21 with a battery in place that was supposed to power the refrigerator, freezer and a master-bedroom circuit for her husband Matthew’s CPAP. Within days the battery dropped to zero (1/19/21), and an unannounced Kosmos visit on 1/30/21 shut the system down abruptly and failed to fix it. During a February outage (Feb 14–16, 2021) the battery did not provide backup: the family went without heat, Matthew could not use his CPAP and they lost the food in their garage freezer — Kosmos offered $250 in compensation. Technicians returned several times through late March, and the issue was not fully resolved until 4/11/21, when the system began producing usable credits again. More problems surfaced in 2022 when she discovered on 6/11/22 that the inverter had been out, costing significant production in April–early June; a replacement arrived but proved defective, then a second inverter was installed on 7/13/22. Since that install the system has

Jason shopped around, chose Kosmos, and two years later still calls them the best in town. He ended up with a solar installation that has held up well — he highlights fair pricing, genuinely helpful service, and solid workmanship as the reasons. The turning point came during the quoting process: a competing company, Spark Solar, nearly quoted him almost double the price for a system that would have produced less power, so comparing offers saved him a lot of money. He urges other buyers to always get multiple quotes and compare output as well as price. The detail that sticks with him is the stark price-and-performance gap between quotes — and two years of trouble-free operation that confirmed he made the right choice.

Joshua, who works in the construction industry, had rooftop solar installed and checked the result one year later with a professional eye. He found the installation crew highly skilled and the workmanship solid, with communication through the process being fairly good. He remains pleased with the rooftop system’s performance and the quality of the install. The memorable takeaway: someone used to evaluating construction still approves the crew’s workmanship a year on.

Ana purchased an 8kW solar system from Kosmos seven years ago for her home. Over that time she encountered only a couple of minor issues, and Kosmos stepped in and fixed them immediately. The two still keep in periodic contact, and she continues to be very happy with how the system performs and with the company's responsiveness. The detail that sticks is the long-term follow-up: years later Kosmos remained reachable and prompt when problems arose, earning her enthusiastic, 1000% endorsement.

Kemi was referred to Kosmos Solar by Tesla when she started exploring rooftop panels for her home. Corbin and his partner came for the initial visit and immediately stood out by walking her through how a solar system actually works — the first company to give that level of clear, hands-on explanation — which made her feel confident about the technology. Corbin kept steady, patient contact after that: answering every question, staying in touch, and never pressuring her to decide, a steady approach that helped her commit. From the credit application to the final installation the process moved smoothly, promises were kept, and the crew proved reliable. What she remembers most is that blend of expert explanation and low-pressure, attentive service — the specific detail that turned the switch to solar into an easy, reassuring experience.

Armando had solar panels installed by Kosmos Solar just over a year ago on his home. He discovered he hasn’t had an electrical bill since the system went live — concrete proof, he says, that the array delivered the output Kosmos predicted. After a year of data, he found their production estimates to be very accurate. He worked with Parry to acquire the system, and Parry’s professionalism became a defining part of the experience: no high-pressure tactics, patient answers to a barrage of questions, and a willingness to research the extra-detailed ones. Kosmos kept that same attention after the install, periodically checking in to make sure any new questions were answered. The detail that sticks: a year of zero bills coupled with a salesperson who actually followed through on technical questions and ongoing support.

TJoseph had Kosmos Solar install a rooftop system on his home in 2017, and what began as a plan to shave his electricity costs turned into an unexpected win: the array is producing a little more than the company projected. He watched a previous $250 monthly bill flip to a negative balance — now showing a $150 credit — and remains very happy with the system’s performance.

John B. bought a home solar system in early 2022 and kept having problems. The installer came back four separate times to repair it, and when the array failed yet again he called repeatedly only to get voicemail. He then discovered the company has closed permanently. Now he’s left with a nonworking system and an unresolved warranty—he’s trying to find out how to transfer that coverage after the installer disappeared.
