As the solar industry continues to grow and evolve, module blending can offer practical solutions for reducing project cost, particularly as antidumping and countervailing duties (AD/CVD) tariffs could be applied to Chinese products and US domestic content is incentivised. There are strategic considerations for designing and constructing solar sites with blended modules.
While it is common to have a mix of different module power ratings within the same type of solar module, module blending specifically refers to using different types of solar modules — varying in manufacturer, cell size, cell count, cell technology and more — within the same project site. This approach is often driven by the need to navigate supply constraints, value economic incentives and realize tariff relief. For instance, with the Inflation Reduction Act (IRA) mandating that products be domestically manufactured or sourced from approved regions to qualify for certain tax credits, blending modules may be a viable strategy to meet these criteria while managing costs effectively.
