Why American-Made Solar Panels Matter in 2025
Over the past few years, interest in domestic solar production has skyrocketed. Why? Because buying American-made solar panels supports local jobs, reduces dependence on foreign supply chains, and often ensures better compliance with ethical and environmental standards.
The Inflation Reduction Act (IRA) of 2022 supercharged this movement by offering incentives for U.S.-based solar manufacturing and deployment. As a result, companies like First Solar, Qcells, and Canadian Solar have ramped up their American production facilities, making it easier than ever to go green and buy local.
In addition, solar projects using American-made panels may be eligible for enhanced tax credits, particularly those adhering to “domestic content” requirements under the IRA. This makes American panels not just patriotic but financially practical.
