SUNation Energy designs, installs, and maintains rooftop solar and battery storage systems for residential and commercial customers, operating primarily on Long Island, New York and in Hawaii. Residential homeowners make up roughly 85% of revenue, with commercial and institutional clients representing the balance. The company's core product is a rooftop photovoltaic system, typically paired with battery storage, which allows customers to reduce reliance on grid power — a particularly compelling value proposition in New York and Hawaii, where electricity rates are among the highest in the country. SUNation sells directly to customers and recognizes revenue milestone-by-milestone during installation, with payment typically flowing from third-party solar loan providers. Beyond installation, SUNation generates revenue from service and maintenance (including "orphaned" systems whose original contractor has gone out of business), roofing, community solar, and grid services in Hawaii through a virtual power plant program. SUNation's stated growth strategy is to become a national consolidator of regional solar installers through M&A, targeting companies with revenue above $20M, positive EBITDA, and diversified revenue streams. The company intends to preserve local branding post-acquisition while spreading procurement and back-office costs across a larger base. With the residential federal tax credit (Section 25D) expiring at end of 2025, SUNation is developing lease-to-own and third-party ownership financing options to sustain residential demand, while its commercial backlog — supported by a longer-dated federal tax credit — is growing heading into 2026.
