GameChange Solar Corp. filed GameChange Solar Corp. v. Nextpower Inc., No. 1:26-cv-01136 (D. Del.), on September 9, 2026. GameChange describes itself as a utility-scale solar tracker company; Nextpower is a Delaware corporation based in Fremont, California.
Patents and accused products
The complaint asserts U.S. Patent 12,449,161 ("Self-Shielding Photovoltaic Module Tracker Apparatus"), issued October 21, 2025. Asserted claims: at least claim 1. The accused product is Nextpower's NX Horizon with Hail Pro solar tracker. GameChange seeks a permanent injunction, damages, an accounting, exceptional-case fees, and related relief.
What the patents cover
U.S. Patent 12,449,161 (Self-Shielding Photovoltaic Module Tracker Apparatus) covers a solar panel assembly with parallel arrays, including a windward perimeter array whose rotatable shaft is sized for torsional stiffness so rows can be controlled and stowed in a self-shielding way. Asserted claims: at least claim 1. Claim 1 covers a solar panel assembly of substantially parallel arrays with a windward perimeter array, each array on racking with a stationary structural member anchored to the ground, configured for that self-shielding tracker architecture.
What the lawsuit is about
GameChange alleges that NX Horizon with Hail Pro directly, indirectly, and contributorily infringes at least claim 1. It points to Nextpower marketing of high-speed, high-angle stowing (including about 75 degree stow), weather-responsive and forecast-driven autonomous stow, and related controls. GameChange also says it contacted Nextpower before suit.
What it means
This is an operating-company solar hardware fight in Delaware over hail-stow tracker mechanics, and it may sit alongside Nextpower's earlier Delaware case against GameChange.
