Noria Energy launches single-axis tracker for floating solar applications

A California company called Noria Energy has built a new system for floating solar panels — the kind installed on reservoirs and other bodies of water instead of rooftops or fields. The product, called Airon, tilts panels to track the sun through the day, rather than staying fixed in one position like most floating solar setups. Noria says this boosts electricity output by up to 20% compared to fixed floating arrays, while costing about the same to install.

This is mainly utility-scale news rather than something that affects home solar directly, since floating solar is used on reservoirs and other large water bodies, not residential rooftops. But it points to where solar technology is heading: getting more power out of the same equipment and site, which can matter for local utilities and municipalities looking to add clean energy without using up land.

Noria tested an early version of the system at a reservoir in Golden, Colorado, in 2025. The company now plans a first commercial installation in late 2026, with full shipments to customer sites starting in mid-2027. It has also brought on two partners — AccuSolar, which will manufacture the hardware domestically, and Sunrock Distributed Generation, which will help finance and develop projects. Because the components are sourced through a U.S. supply chain, developers using the system may also qualify for domestic-content bonuses under federal clean energy tax credits.
