Type: Financing · Technology: Solar · Country: United States · Value: $100M · Announced: 2026-08-13

Tandem PV announced it has secured $100 million in financing from a group of investors including Eclipse Ventures, Constellation Energy, Planetary Technologies, Trellis Climate and 8090 Industries. The capital will be used to advance its perovskite‑silicon tandem solar panel technology and to build a high‑volume manufacturing line targeting gigawatt‑scale output by 2028. The financing package combines equity, debt and grant components, reflecting confidence in the company’s 30.4 % efficiency record module and its roadmap toward 34‑37 % efficiency panels. By leveraging domestic content credits and a $0.40/W average selling price, Tandem aims to capture a material share of the U.S. utility‑scale IPP market, which accounts for roughly 80 % of domestic solar installations. The deal was disclosed in an interview with PV Magazine USA on 13 August 2026, with no specific closing date provided.
