PosiGen

What PosiGen does

PosiGen was a privately held residential solar installer founded in 2011 and headquartered in New Orleans, Louisiana. The company sold and installed rooftop solar and energy efficiency systems directly to low- and moderate-income homeowners in underserved U.S. communities, a segment traditional solar providers had largely ignored. PosiGen operated a direct-to-consumer go-to-market model, reaching customers across 15+ states and Washington, D.C., and had deployed systems for 40,000+ households by the time of its collapse. The company differentiated through mission-aligned branding, community-level trust-building, and access to mission-driven capital sources.

PosiGen's revenue model centered on hardware sales (residential rooftop solar systems) and related installation services, supplemented by energy efficiency upgrades. Financing for customer acquisitions was enabled through institutional funding partnerships, most notably a series of debt facilities and equity investments from Brookfield Asset Management totaling $600 million since 2023, alongside earlier equity rounds led by Magnetar Capital ($100M preferred, January 2022) and debt from Connecticut Green Bank, ImpactAssets, and Inclusive Prosperity Capital. The company leveraged public incentive programs — notably the Inflation Reduction Act and state green bank capital — to make solar financially accessible to LMI households.

The company's independent operations ended when it filed for Chapter 11 bankruptcy in November 2025 with at least $100 million in debt. Creditor challenges subsequently surfaced double-pledged assets and commingled funds. In February 2026, Renewbrook Energy — a Brookfield portfolio company — acquired the majority of PosiGen's residential rooftop systems and customer contracts, with servicing transferred to Renewbrook (supported by Omnidian), Sunstrong, and GoodLeap. The entity is now classified as closed; its underlying assets continue to operate under successor ownership rather than under the original PosiGen brand.
