Renu Energy Solutions

In 2010, Jay Radcliffe founded Renu Energy Solutions in Charlotte with a straightforward mission: make solar energy accessible, reliable, and worth the investment for homeowners and businesses across the Carolinas. What began as a local solar installer in Charlotte has grown into one of the Southeast’s most established solar companies, now with regional offices in Columbia, Asheville, Cary, and Greenville. Over the past 15 years, Renu Energy Solutions has completed over 7,000 residential and commercial solar installations throughout North Carolina and South Carolina, powering homes and businesses with clean energy while maintaining the personal touch of a locally owned company. Every team member lives in the communities they serve—Charlotte, the Triad, Upstate South Carolina—giving them genuine insight into what Carolina homeowners need from their solar installer. Unlike national companies that rely on subcontractors, Renu employs an in-house team of W-2 installers, electricians, and project managers who handle every aspect of the solar installation process from consultation to activation and beyond. The company holds NC and SC general contractor and electrical licenses, maintains an A+ BBB rating, and employs nine NABCEP-certified professionals who bring proven expertise to every project. Renu specializes in residential and commercial solar panel installations, battery storage systems from Tesla, Enphase, and FranklinWH, and EV charger installations. They’ve installed over 1,000 energy storage systems and maintain over 10,000 solar and battery systems across the region. Through its sister company, Sun Service Specialists, Renu also provides ongoing maintenance and repair for systems they install—and even those installed by other companies. In February 2024, Renu was acquired by Swell Energy to expand Virtual Power Plant capabilities across the Southeast, positioning the company at the forefront of grid-connected home energy systems. For Charlotte homeowners considering solar energy, Renu offers custom system design tailored to roof size, energy usage, and budget, plus comprehensive warranties including a 10-year workmanship warranty, 5-year roof warranty, and 5-year production guarantee. The company is a Duke Energy Trade Ally, which means customers installing solar plus battery storage can access the PowerPair incentive program offering up to $9,000 in rebates. Renu has been recognized on the Inc. 5000 Fastest-Growing Private Companies list and named a Top Solar Contractor by Solar Power World. With over 100 Carolina-based employees, the team takes pride in educating homeowners about solar installation without high-pressure sales tactics, providing transparent communication throughout the process, and delivering systems built to perform reliably for decades.
