Full Analysis
PosiGen, a Louisiana-based residential solar company, filed for Chapter 11 bankruptcy in November 2025. The company attributed its financial distress to significant changes in renewable energy policy, specifically the Trump administration's de-prioritization of tax incentives for solar panels. Additionally, the imposition of steep tariffs on imported materials essential for solar projects, such as solar modules, inverters, racking, and structural steel, dramatically increased their operational costs. The effective tariff rate for imported solar cells and panels surged to approximately 20% after May 2025, up from less than 5% in previous years. This substantial increase in import duties, amounting to close to $70 million a month for common panel types, placed immense strain on the company's finances, making it difficult to maintain profitability and compete in the market.
