Core Energy Group reviews

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

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.

Susana P paid $45,000 for a 10-panel solar system and ended up with panels that still haven’t been switched on after 17 months. She discovered the crew installed the array even though they knew her breaker box couldn’t handle the setup, leaving the system unusable. Feeling misled by promises, she warns other buyers to "get everything in writing." The lasting image: a costly rooftop of panels that produces no power because the underlying electrical compatibility was never resolved.
