Expansion of domestic solar manufacturing supply chains is expected to strengthen the U.S. solar PV market in 2025

The solar photovoltaic (PV) market is expected to witness strong growth in 2025–2026 due to increasing investments in localized and vertically integrated manufacturing supply chains aimed at improving energy security, reducing import dependency, and supporting renewable energy deployment targets. Governments and private players are increasingly focusing on building end-to-end domestic solar ecosystems covering polysilicon, wafers, cells, and module production. In March 2025, Corning Incorporated, Suniva, and Heliene announced the first “Made in America” solar module supply chain, integrating U.S.-manufactured polysilicon, wafers, and solar cells to produce fully domestic solar modules. The initiative is expected to strengthen supply chain resilience, enhance energy independence, and support the growth of local manufacturing capabilities in the U.S. solar industry. Additionally, rising policy support for renewable energy localization and increasing demand for high-efficiency solar modules are expected to further accelerate market expansion during the forecast period.

Strategic polysilicon and wafer supply agreements are expected to accelerate U.S. solar manufacturing capacity expansion in 2025–2026

The solar manufacturing market is expected to experience continued expansion in 2025 as companies invest in long-term supply agreements to stabilize raw material availability and support large-scale solar deployment. Increasing demand for clean energy infrastructure and government incentives for domestic renewable manufacturing are driving investments in vertically integrated solar production facilities. In August 2025, T1 Energy and Corning Incorporated announced a strategic commercial agreement to strengthen the U.S. solar supply chain by sourcing hyper-pure polysilicon and solar wafers from Corning’s Michigan facility. Starting in the second half of 2026, these wafers will be supplied to T1 Energy’s solar cell and module manufacturing facilities, supporting a fully integrated domestic production model. The agreement is expected to enhance supply chain stability, improve cost competitiveness, and support large-scale solar deployment in the United States. Furthermore, increasing focus on energy resilience, job creation in advanced manufacturing, and clean energy transition policies is anticipated to further strengthen the global solar PV market.
