RNR Solar reviews

The Verdict
RNR Solar poses clear risk and is not worth the gamble. We found multiple reports of catastrophic utility billing failures, property damage during installation, and an owner who goes silent when customers need help. One homeowner discovered a year after install that their monitoring system was never linked to the utility, resulting in a $1500 surprise bill even though the panels had been generating power the entire time. When they tried to reach owner Gregg Miller about the setup error, he promised a call and then ghosted them. Reviews also document delayed installs, conduit runs that destroyed fresh exterior paint, and roof tiles left behind chimneys for months. We noticed aggressive door-to-door sales tactics with daily calls and texts even after prospects declined. The company's roofing work has a decent track record (25 reviewers praised workmanship quality on roof replacements), but the solar operation shows a pattern of broken promises and vanishing support when billing or technical issues surface. A company that won't return calls about a four-figure utility mistake is a company that will leave you holding the bag.
If you're comparing solar installers, cross RNR off your list. Their roofing crew may be competent, but the solar side shows serious gaps in utility coordination, installation care, and post-sale accountability. You'll find more responsive support elsewhere.
Reviews That Shaped Our Verdict
Shawn arranged for solar on his home and watched the project unravel. The crew showed up a couple of months after the scheduled install date, ran conduit across the exterior and ruined fresh paint, and left a roof tile behind the chimney that took repeated requests and months to get removed. About a year later he discovered Edison had put him on an annual billing plan and hit him with a $1,500 bill — because the installer never properly linked the system’s Enphase setup with Edison, the solar he generated hadn’t been credited. He tried to get the owner, Gregg Miller, to sort it out; Gregg promised a call and then repeatedly failed to follow up. Shawn has retained an attorney and is moving forward with legal action. The lasting, specific takeaway: property damage and months of unresponsiveness combined with an entire year of uncredited solar that resulted in a $1,500 unexpected bill.
David S. found his quiet suburban weekend interrupted when solar solicitors started knocking on doors in the neighborhood. His wife had unintentionally given them their number, and after that the company contacted him by text and phone, leaving a voicemail every single day and even returning on a weekend to try to speak in person. He told them they couldn’t afford a new roof right now, but they kept pressing him to meet, insisting on city rebates and payment programs that might make the work possible and refusing to accept no. The salesperson insisted a site visit wasn’t necessary, claiming they used Google Maps to measure square footage — which left him wondering how they could possibly determine roof slope without looking. Noticing they weren’t local and watching the nonstop solicitation, he felt alarmed; the company’s persistence and remote estimating set off his don’t-use radar.
Piers B. rarely posts reviews, but after work on his 1908 Craftsman he made time — the house has a lot of steep roof, and the change was dramatic. Rodney from R&K Roofing steered him to RNR Roofing, and Piers trusted that referral. From the first contact Gregg Miller laid out clear, regular timelines and cost expectations without any hard sell. When Gregg suggested cedar instead of the asphalt composition they’d originally considered, he sketched out how hidden ancillary costs for a new composition roof would balloon the price; a competing bid later confirmed Gregg’s projection, so they opted for cedar. Gregg also pointed out that the house was built for cedar, that the earlier conversion to composition had relied on liberal mastic around dormer windows and the porte-cochere (which had become a damp trap after heavy 2020 rains), and that the plywood base used for composition had been trapping heat and turning the upstairs into a sauna. Gregg promised the cedar would cool the upstairs, and Piers waited through the first 100º+ run in 2021 to verify the claim — the difference was night and day. COVID interrupted material shipments from Canada, but Gregg kept Piers updated and, even on

What You Can Expect
Shawn R. discovered, a year after the system was active, that he owed $1,500 on his Edison annual bill because the installer never linked the Enphase equipment to the utility—so his solar production never registered with Edison. He had already weathered a shaky installation: the crew arrived months after the scheduled date, ran conduit along the exterior and ruined newly painted siding, and left a broken roof tile behind the chimney. He asked repeatedly for the tile to be removed; crews only returned after months of follow-ups. He tried to escalate the problems with owner Gregg Miller, who promised to schedule a call but repeatedly failed to follow through and began ignoring him. Facing unexpected charges and unaddressed damage, he’s instructed his attorney to file suit.

Susan H. had solar installed on her home and found a company that was both budget-friendly and unusually reliable. She appreciated that the crew actually answered the phone and arrived when they promised, which smoothed the whole process. The installation cut her electricity costs to the point she now has effectively free power. Her clear takeaway: ask for Greg when you call — that personal contact made the difference for her.
