Core Energy Group reviews

Kelli W. paid for a rooftop solar system on her single-person home and ended up feeling completely scammed. She waited nearly seven months for the system to be connected, all the while continuing to pay about $200 a month on the loan in addition to her regular PG&E bills. When the crew finally said the system was "ready to use," she discovered it hadn’t been properly programmed or tied into any working setup—so for more than a year the panels sat on her roof but weren’t actually delivering usable power. The consequence was a year-end TrueUp with PG&E of nearly $4,000, and today the array produces less than 200 kWh a month—effectively nothing for a solo household. She ended up paying loan payments for a system that didn’t offset her bills and was left with a large utility bill instead—clear evidence that commissioning, programming, and confirmed interconnection matter before expecting savings.

J R. paid in full for a residential solar system and then waited a year before the crew finally arrived to install it. When work was completed, they found the installation unacceptable — sloppy workmanship and unfinished details. Customer service compounded the problem by repeatedly promising fixes that never came and by ignoring calls and texts. Frustrated, they plan to consult an attorney to pursue negligence and breach of contract. The sharp takeaway: prepaying led to a year-long delay, poor installation, and unreturned communications, and J R. is pursuing legal options rather than relying on the company to make it right.

Kyle had a solar system installed in November 2022, with the loan for the project coming into effect in February 2023. He ended up paying both the loan and his regular electric bill for nine months after the installation. During that stretch company representatives repeatedly promised they would refund the loan payments he made before the system was activated. Two employees specifically promised a reimbursement of $2,258.11, but by May nothing had been done. He remains out $2,258.11 and is still waiting on the promised refund despite repeated assurances.

Estelle J had solar panels installed on her home more than two years ago and ended up with a system that isn’t producing any electricity. She has sent over 50 text messages trying to get someone to come out and diagnose the problem, but heard nothing back. The company limits its responses to phone and text, and once she submits her information nobody follows up. Meanwhile she continues to pay a solar loan while her utility bills remain high—after more than two years and dozens of unanswered texts, she still has a nonworking system and no resolution.

Linda H. has been paying Core Solar for nearly two years but never received the service she expected. She continues to cover her regular utility bill while also paying Core Solar for a system that never materialized — the defining detail of her experience is being billed for almost two years for a product that never delivered any service.

Paulino signed a residential solar contract in January 2023 and by March his household ran into relentless problems. For more than two months he discovered they couldn’t use major appliances—stove and oven, washer and dryer—and had no reliable air conditioning, forcing him to cancel his daughter’s going‑away party during a heat wave. Calls went unanswered, appointments were promised and then missed, and technicians never showed up; when he followed up about a PG&E visit he learned a work order had never even been submitted. The appliances finally started working on the 19th, but only after weeks of extra costs: dining out because the oven didn’t work, laundromat trips for laundry, and a week in a hotel to escape the heat. The company had assured him repeatedly—he asked the question more than six times—that there would be no PG&E annual true‑up and that he wouldn’t need to curb electricity use; instead he received a $2,500 TRU‑UP and regular bills far higher than promised. He was also promised three months’ reimbursement and signed a disclosure agreeing not to speak negatively, yet a year later no reimbursement arrived. Frustrated and feeling misled—he even labeled the company “scam

Jose P began working with the company in mid‑2022 to get solar panels installed on his home. He expected the system to go up last summer, but repeated delays pushed the project out and communication slowed to the point where he now gets only text replies and no direct contact. Meanwhile he has been paying toward a loan for the system despite there being no installation. Frustrated, he has turned to the Better Business Bureau hoping for a resolution — the memorable takeaway is simple and sharp: months of delays paired with loan payments and only text responses.

Rodney S bought a house that already had a Tesla solar setup but found it wasn't large enough, so he had extra panels added. In October 2023, when an inverter replacement was performed, the installer discovered three of the AP Systems panels he'd had added were shattered. He contacted AP Systems, who directed him to his installer, Core Energy, and indicated the damage should be covered under warranty. Core Energy refused to honor the warranty, quoted $500 per panel to replace them, and implied Rodney had damaged the panels; he insists he never touched them and thinks either a defect or the climate caused the breakage after only about 18 months. He points out AP Systems' website references weather-related coverage and believes portions of the warranty run for ten years, so he's prepared to pursue legal action if the panels aren't replaced. What stays with him is the $1,500 repair bill Core Energy demanded while the manufacturer maintains it should be a warranty repair — that disagreement is the central problem he wants resolved.

Alexander invested about $60,000 in a home solar system in July 2022. The salesperson even walked into the house despite Alexander and another household member having COVID that day, an act he appreciated, but the installation and follow-up turned into a long, frustrating saga. It took eight months for the panels to go live, and once they did he discovered overall production far below what had been promised. Two panels produced very little because installers placed them behind trees, and two other panels showed persistent problems on the monitoring app from the start. After asking for help he noticed someone had accessed the system — one module’s display changed in the app — but one panel still showed an error and then communication went quiet. He was promised lifetime free maintenance and given contact numbers; one contact never responded and another initially said it would cost $500 to move the tree-blocked panels. On November 10 a staff member waived the fee and a technician visit was scheduled, but after being persuaded to push the appointment to November 11 no one arrived. Text messages to customer service went unanswered over the weekend. After months of patience, worrying a$
