What RxSun does
RxSun is a full-service residential solar energy consulting company that designs, finances, and project-manages home solar installations for homeowners in Illinois, Michigan, Wisconsin, and Florida. The company employs NABCEP certified designers and engineers to produce system designs and handles the full workflow — home qualification, permitting, grid interconnection, incentive applications (including the 30% federal tax credit and Illinois SREC payments), and project management — while outsourcing physical installation to a locally-based installation partner, Fresh Coast Solar. Underlying technology is conventional residential solar (typical 7.15 kW rooftop systems generating ~965 kWh/month) paired with an online Solar Savings Calculator and an educational Solar 101 content hub; no proprietary AI/ML or software platform is disclosed.
The business model is one-time transactional: customers purchase a solar system outright (often financed through third-party lenders via zero-down or interest-free-for-18-months plans), with RxSun capturing revenue at installation. Ancillary streams include bundled consulting/professional services and a referral program paying up to $500 per installed system to both customers and contractors. Go-to-market is sales-led, combining inbound channels (EnergySage marketplace, website, blog, SEO content), direct phone sales (800-607-9786), field sales consultations, and partner referrals. The company operates an asset-light model with a stated headcount of 1-10 employees out of a single Chicago headquarters (2211 North Elston Ave. Suite 208), and is privately held under private equity sponsor Altimus Capital alongside sister companies Fresh Coast Solar and Verde Solutions.
In 2025 the company completed approximately 500 installations (~25% above 2024), earned a 2025 INC. 5000 recognition, and preemptively halted new orders by mid-August 2025 in anticipation of a projected 50-70% sales decline in 2026 following the federal solar tax credit repeal. The company's customer base is entirely distributed across individual residential homeowners, with no enterprise contracts, and customer acquisition relies heavily on referral and marketplace channels rather than recurring revenue streams.
