GR8 Energy reviews

The Verdict
GR8 Energy will handle your installation just fine but may abandon you afterward. One homeowner called every day for four business days about a failing inverter, leaving urgent messages that production was dropping, and never got a callback. Their system had already cycled through three inverters in six years. Another customer waited over a month for any response while their system sat offline. We found 13 reviews describing post-installation support failures: unanswered calls, ignored emails, monitoring app issues left unresolved for months. The pattern is consistent enough that it outweighs the early positives. Yes, 40 reviewers praised the installation workmanship and several mentioned fair pricing. One installation wrapped in two days, another reviewer watched their electric meter spin backward right on schedule. But the value of a smooth install evaporates when your system stops producing and the company goes silent. The referral program took six months to pay out, forcing the salesperson to cover it from his own pocket. An installer promised to return after Thanksgiving to fix a wifi sync issue and simply never showed, never called, never texted.
If you want panels installed quickly and cleanly, GR8 Energy can do that. But if you expect someone to pick up the phone when your inverter dies two years later, you're rolling the dice. The gap between their installation performance and their post-sale responsiveness is too wide to ignore.
Reviews That Shaped Our Verdict
Kelsey J. bought a solar system from GR8 Energy six years ago and has already gone through three inverters. For the past four business days she and her husband have called every day and left multiple urgent messages trying to get a callback. Meanwhile the array is losing production each day as the current inverter weakens; she needs an installer to come out and assess the problem, but nobody has returned their calls. The contrast is sharp: the company shone during the sale, yet fell silent once the system was installed and issues began. The detail that lingers is concrete — three inverter replacements in six years and a system losing output while the owner chases support — a practicality buyers should factor into post-sale expectations.
Luke R. hired GR8 Energy to put solar on his home and quickly ran into a string of problems. He discovered the installer used ballasts the inspector rejected, which stalled the job and added several thousand dollars in unexpected cost. That led into more hold-ups: trouble securing inspection approval, delays getting the PTO, and voltage issues that caused additional setbacks and further thousands in expense. What began as a straightforward install stretched out to nearly two years and inflated the project by about $6,000. After the system finally ran for a few months it stopped responding and stopped generating, and he hasn’t been able to reach anyone at GR8 Energy for over a month. The end result: a long, expensive ordeal with an idle array and no effective aftercare.
Jose M. moved forward with a residential solar purchase after a smooth sales process and clear explanations from Earl Kapule, the salesperson who stood out for his help. He found the buying and installation steps easy, but the problems began after the system was live. For months he kept getting an alert that the Envoy monitoring unit wasn’t reporting. He followed the app’s step‑by‑step troubleshooting exactly and still saw no improvement. The week before Thanksgiving he called the office; a technician checked remotely, said only an employee-only app could re‑sync the Envoy to his Wi‑Fi, and suggested the unit’s antenna might be faulty. The tech promised someone would contact him Thursday and that he himself would follow up, but Jose’s calls and texts to that technician went unanswered. He left multiple voicemails for the company, sent emails, and even messaged Earl for help, yet heard nothing back—same voicemail greeting even after the holiday. On top of the monitoring issues, a promised referral payment stalled. After Earl earned his trust, Jose referred friends to GR8 Energy. The first referral paid promptly after installation, but the second stayed “pending” in the referral app.

What You Can Expect
Shweta K. had panels installed more than a year ago and remembers the initial job as prompt and well executed — quick responses and a solid installation left a good first impression. When she started planning to buy an electric car, she reached out to Ross and Grace at Gr8 Energy for a quote to add roughly five or six panels. Months passed with no reply, so she phoned them herself; they asked her to book an appointment and promised to call back in three days. They finally talked, went over the additional panels, and then silence returned for nearly a week. She ended up frustrated by the contrast: excellent service at installation, but slow to nonexistent follow-up when she needed an upgrade quote. The detail that sticks is the disconnect between a flawless initial install and the company’s unreliable post‑sale communication about EV readiness and extra panels.
Paul M. had a great experience with his original solar installation about three years ago — knowledgeable staff, competitive pricing — and felt confident in the system. Lately he discovered a roof leak and has spent a month trying to get Ross and his crew to remove a few panels so the roofer can find the leak’s source. He has left numerous phone messages while the roofer has cleared his schedule and offered to come out any day or time that’s convenient for GR8. With more rain on the way, the situation feels urgent, and he’s grown increasingly frustrated by the lack of customer service and cooperation. At this point he may have to hire a different Cooperative solar person to take the panels down and put them back up just to get the leak fixed before the next storm.
David marked his one-year true-up with SDGE and discovered his bill was essentially zero after Ross installed his home solar system. Wanting a safety margin, he had Ross add one extra panel beyond the original recommendation. Since activation he has encountered no issues with the equipment or service. The memorable detail: a slightly oversized array and a smooth installation translated into a true-up bill that was practically nothing.
