Rose Energy LLC

★★★★★5.0(20 reviews)
88Score

Rose Energy LLC holds a 5-star rating from 20 reviews, showcasing high customer satisfaction. Clients often highlight their personalized service and attention to detail, which makes them a great pick for homeowners seeking custom solutions. However, their limited number of reviews makes their overall reliability somewhat less established. The review base is still thin, so we read the rating as promising rather than proven and weighted it accordingly. Most of what reviewers hire it for is custom solar solutions. It serves Rock Hill, SC, with $10,000 to $20,000 pricing, and the honest trade-offs are limited number of reviews and less established in the market.
