What SUNation Energy does
SUNation Energy, Inc. (NASDAQ: SUNE) is a U.S. residential and commercial solar installation and energy services company headquartered in Ronkonkoma, New York, founded in 2003 by Scott Maskin. The company installs photovoltaic solar systems (monocrystalline and polycrystalline silicon panels), battery storage (Tesla Powerwall, Enphase Encharge, Goal Zero), EV charging stations (Tesla, JuiceBox), and GAF Master Elite-certified roofing, primarily serving homeowners and select commercial/nonprofit customers in high-electricity-cost markets — Long Island, New York City, Florida, and Hawaii — through brands including SUNation, Hawaii Energy Connection, E-Gear, and SUNation Roofing. SUNation has installed 10,000+ systems representing 130+ MW of capacity and was the #1-ranked solar contractor in PSEG Long Island's service territory in 2025 with 9.3 MW deployed.
The company generates revenue primarily through one-time installation fees for solar systems, supplemented by recurring maintenance/service revenue (SUNation Service), battery and EV charger hardware sales, roofing projects, and community solar subscription programs. Pricing is quote-based and not publicly disclosed; customer-facing economics are supported by federal (up to 30%) and New York state (up to $5,000) tax credits, alongside lease and PPA financing arrangements facilitated through Palmetto (LightReach) and Participate Energy partnerships. FY2025 revenue was $71.9M (26% YoY growth) with positive Adjusted EBITDA of approximately $2.5M and gross margins in the high-30% range; Q1 2026 revenue declined 43.1% YoY to $7.2M following Section 25D federal tax credit expiration. In April 2026, the Board initiated a strategic alternatives review, culminating in a June 2026 reverse merger agreement with Suniva — the largest U.S. merchant manufacturer of monocrystalline silicon solar cells — under which pre-merger Suniva stockholders will own approximately 98.2% of the combined entity, with closing expected in H2 2026.
