Core Energy Group reviews

idcatlady Hoho discovered that the company that installed her home solar system quietly folded in June under the guise of a "merger," without notifying customers. When the inverter later failed, she had to hire a local firm that charged $750 to diagnose and repair it — and the tech determined the fault was a simple mistake the original installer had made. Core had also told her one of the system batteries was functioning, but the replacement team found that battery completely without charge. She learned that employees and the CEO of Solgen Construction/Core Energy have moved into new jobs, leaving existing customers abandoned while those staffers take on new clients. The lasting impression: an unexpected $750 bill and a dead battery she was told was fine — a tangible cost and inconvenience from an installer that disappeared midstream.

Haley Perez contracted the company to install solar on her home and, nearly a year later, still didn’t have a working system. She documented every interaction — collecting contracts, text-message threads and email exchanges — and has been printing the full paper trail to present to an attorney as she figures out next steps. Along the way she learned that someone who had worked for the company was never paid for installing her system and for many other jobs. Frustrated and alarmed, she labels the company scammers and urges others to avoid the same drawn-out, unpaid mess; the standout fact is simple and sharp: almost a year with no panels producing power and a folder of evidence ready for legal action.

M had a short, unpleasant encounter with the installer: after handing over payment, they heard nothing more from the company. Expecting either an installation or at least routine follow‑up, they found communication stopped and no work materialized. M left a one‑star review and labeled the experience a scam — the striking detail being that money left their account but contact did not.

Kelli Walker felt completely scammed after a residential solar installation that turned into a long, costly ordeal. She waited nearly seven months for the system to be connected while still paying about $200 a month on the loan in addition to her regular utility bills. When the company finally said the array was "ready to use," she discovered it hadn’t been properly programmed — and for over a year the panels sat on her roof without being tied into a system to use the power they produced. That failure left her with a nearly $4,000 TrueUp bill from PG&E at year’s end. The bottom line she walked away with: months of loan payments plus utility charges and a hefty TrueUp made the solar project more expensive than staying on the grid.

Ferman Perez contracted a residential solar installation and more than a year later is still waiting for the company to finish the job — the project remains incomplete.

Alissa Holiday initially left a five-star review after crews showed up quickly and put panels on her roof, giving the impression the installers knew what they were doing. She discovered, more than eight months later, that the work stopped at the rooftop: the company never finished the electrical hookup, so she’s been paying for the solar system while still writing checks to SCE because the array isn’t functional. Repeated attempts to reach anyone at the firm went nowhere; post-installation support disappeared and she was left dealing with an unfinished job. The experience turned from promising to deeply frustrating — eight months on, a paid-for system that doesn’t produce power and a company that won’t answer is the core warning she offers to anyone considering Core Energy Group.

Nani Zara arranged for the company to install solar panels on her parents’ house; crews finished the work at the end of May. When she checked afterward, the array was just sitting on the roof — never switched on — and the inverter/meter readouts weren’t working, so the system produced no power. She emailed repeatedly trying to get help but couldn’t reach anyone or get a reply. As of the review the panels remained inactive and she left a one‑star rating. Takeaway: confirm a firm activation date and written communication commitments before signing, because installation can be completed without the system ever being turned on.

Gabriel Gonzalez paid for a solar installation and discovered the company went silent after receiving his payment. He waited as work progressed at a crawl, repeatedly got no replies from the team, and watched promised incentives evaporate once the money changed hands. Communication broke down, the system still isn’t working, and he concluded the whole operation felt like a scam. The detail that sticks: salespeople promised incentives up front but those incentives never materialized after payment, leaving him with a nonfunctional system and no recourse.

Maria L. had her solar panels installed without issue, but the trouble began with the sales side. She trusted an agent named Tim after he offered a $1,000 referral bonus; she kept records of that offer and other communications, yet Tim never delivered the payment. He apologized at one point and later texted that his phone had been disconnected, leaving her holding the documentation while he failed to follow through. On top of that, the financing company Mosaic promised to reimburse three payments she made while PG&E had not yet connected the system. She kept proof of those payments as well, but nearly a year later Mosaic has still not paid and keeps blaming a broken checking system for the delay. She ended up with a working installation but unresolved money promised by both the salesperson and the financier. With texts, payment records and timestamps in hand, she is preparing to take the matter to civil court if the company doesn’t make good.
