Renu Energy Solutions

Renu Energy Solutions has spent the better part of fifteen years building one of the most established residential solar practices in the Carolinas, and what stood out to our research team is the depth of their in-state credentialing. Founded in 2010 by Jay Radcliffe, Renu carries both a South Carolina General Contractor license (#119903) and a South Carolina Electrical Contractor license (#CLM.113782), and the company maintains an A+ rating with the Better Business Bureau where it has been accredited since 2017. Their Columbia office at 2711 Alpine Road anchors a broader SC footprint that includes a Greenville warehouse and active project work across Charleston, Columbia, and the Upstate. Across the Southeast, Renu reports more than 6,000 solar installations and over 1,500 energy storage installations, with a 4.6-star Google rating across 557 reviews.

On equipment, Renu installs CertainTeed solar panels paired with Enphase and SolarEdge inverters, and the company is a certified installer for Tesla Powerwall 3, FranklinWH aPower 2, Generac PWRcell 2, and Enphase IQ battery storage. Their NABCEP certification (#090919-017323) and W-2 in-house installation crews — rather than subcontracted labor — were factors that contributed meaningfully to their score. They are recognized as a Solar Power World Top 500 Solar Contractor every year from 2013 through 2021, an Enphase Platinum Installer, a Tesla Certified Installer, and a Generac Premier dealer.

Prospective customers should also be aware of the company's recent ownership history. Renu was acquired by Swell Energy in February 2024, and Swell subsequently entered an assignment-for-the-benefit-of-creditors liquidation process in early 2025. Renu itself, however, has continued to operate in the Carolinas through 2026, with documented installations and permitting activity confirmed across the period and an active office presence in Columbia. Our research team did flag a number of BBB complaints involving design errors, post-installation responsiveness, and project delays — issues common to mid-sized regional installers, but worth raising directly during the sales process. Homeowners should ask pointed questions about warranty backing, service-call response times, and how Renu structures its in-house electrical work versus permitting handoffs.

With a composite score of 78.4 out of 100, Renu Energy Solutions stands as our top-ranked solar company in South Carolina for 2026.
