Slingshot Power reviews
• last updated FEB 26, 2026Loading map...
The Verdict
This company is not safe to hire. We found a disturbing pattern: systems installed years ago sit broken for months or years while customers chase repair techs who never show up. One homeowner discovered a faulty panel in March and was still waiting in July after repeated calls and emails. Another waited six months and fifty phone calls to fix dead panels in 2020, only to face the same ghosting cycle when trying to schedule panel removal in 2023. The workmanship score of 3.9 looks decent until you see what happens after installation. Post-sale support earned a 2.2 out of 10, anchored by 57 negative mentions. Twenty-four reviews describe systems that stopped producing power entirely while warranty requests went ignored. Eight customers reported roof leaks tied to the installation, and one paid $600 out-of-pocket to fix ceiling damage because the company stopped responding. The owner promised fixes, sent texts confirming appointments, then vanished. One customer even received a bounced $500 referral check. The company appears to have closed its residential division, which means your 25-year warranty may already be worthless.
If you're weighing Slingshot against other installers, cross them off the list. The equipment may work fine for a few years, but when something breaks or your roof starts leaking, you'll be stuck chasing ghosts. Pay more for a company that answers the phone.
Reviews That Shaped Our Verdict
Jan J. discovered Slingshot Power appears to have shut down its residential arm, but could only find a Yelp listing to suggest that. They had a system installed in 2014 and appreciated the quality of the install and the professional approach early on. That positive start unraveled when an optimizer failed in 2020 and replacement never happened. They made repeated phone calls — including conversations with Paul S., the owner — opened two tickets with SolarEdge, and were repeatedly promised a technician, yet no one showed. Contractual service obligations went unacknowledged, leaving a single faulty component unresolved for years. The standout detail for a prospective buyer: solid installation work, but long‑term service vanished — an optimizer still out of commission since 2020 despite owner contact and vendor tickets.
Prakash had a residential solar system installed in 2016 — the installation itself went smoothly and the price looked very good. But in 2020 he discovered a couple of panels had stopped working and spent months fighting for a fix: roughly 50 phone calls, repeated rescheduling and at least three service visits before the problem finally got resolved after about six months. Fast forward to 2023 during a roof remodel, he needed the array removed and began a three-week scramble to get the company to respond; most calls went to voicemail and scheduling happened without a written contract because the crew was "too busy" to send one, yet they demanded an upfront payment. On the day they were supposed to uninstall, there was radio silence until late; eventually Paul arrived with two men in jeans and T‑shirts in a beat-up car, no work van and no proper equipment. After a quick look they announced they needed a different hex drill and drove off to the nearby Home Depot, disappearing at 3:30 and not returning until about 4:45; when Prakash called at 5:00 he was told they were back, only to find the roof dark and no one on site and no courtesy reschedule. Between the earlier six‑month repair t
A A. had Slingshot install a solar system on their home in the summer of 2020 and discovered a pattern of failures almost immediately: each year the inverter or the LG battery backup malfunctioned, and every inverter failure left them without solar for at least a month. The most recent breakdown began on March 29, 2024. Slingshot hired a third party for service; a technician named Greg opened a case with SolarEdge, but by April 29 the inverter replacement was still pending and SolarEdge could not give a delivery date. They learned their LG backup model had been subject to a recall, and when Paul sent an electrician to check the backup setup the electrician found the critical backup panel configured incorrectly. The panel only supplied 25 amps total — far too little to run the three items the homeowner had designated as critical. The installer had told them they could pick three items to be backed up but never explained how many amps each item would need. As a result, every outage knocked those items offline; even after the utility (PGE) restored power, the three designated circuits remained dead. Two of those items were refrigerators, and foods spoiled during summer outages while

Ogen had Slingshot put a 30-panel system on his roof about nine years ago under a contract that promised remote monitoring and a free annual panel cleaning—services that never materialized. Over the past few months several panels stopped producing, and on closer inspection he discovered the crew hadn’t installed the contract-specified SunPower panels with SolarEdge optimizers but had used ABB microinverters instead. ABB (now Fimer) told him they can’t determine warranty coverage without voltage measurements that only the original installer can take. Paul, the installer who had been personable during the job, has been ignoring calls, texts and emails, so the warranty process stalled. He also found the installation didn’t follow the manufacturer’s specs: installers tied too many inverters onto a single trunk, which likely contributed to the failures. The end result is a partially nonfunctional 30-panel system, no manufacturer support until Slingshot cooperates, and an owner stuck in limbo after nearly a decade—what stands out is that a named installer’s lack of follow-through, not just product problems, is what’s blocking a warranty resolution.
