North America Bi-facial Solar Market Outlook, 2031

Market Drivers

• Utility-Scale Bifacial with Tracker Integration: The pairing of bifacial modules with single-axis tracking systems has fundamentally transformed utility-scale project economics across North America. Bifacial modules now represent over 60% of utility-scale ground-mounted installations in the United States, as albedo gains of 5-15% improve project economics on tracked systems. NREL data shows bifacial adoption in systems exceeding 5 MWdc growing from 5% to 78% of capacity between 2020 and 2024. The Department of Energy's investment of $14 million across eight projects specifically targets extending system longevity and increasing reliability of bifacial and thin-film solar technologies, further strengthening the technology's value proposition.
• Domestic Manufacturing Expansion and Supply Chain Localization: The North American bifacial solar market is witnessing an unprecedented manufacturing renaissance driven by federal incentives and supply chain resilience imperatives. Module manufacturing capacity surged more than 50% in 2025 to reach 65.5 GW, up from 42.5 GW at the end of 2024, while wafer capacity came online for the first time since 2016. The U.S. solar industry added 8.6 GW of new solar module manufacturing capacity in Q1 2025, marking the third-largest quarter for new manufacturing capacity on record. ES Foundry's South Carolina facility now delivers high-efficiency monocrystalline bifacial PERC cells enabling module manufacturers to unlock the domestic content ITC bonus.

Market Challenges

• Trade Policy Uncertainty and Tariff Complexity: The North American bifacial solar market confronts a labyrinthine trade policy environment that introduces significant uncertainty and cost pressures. The U.S. International Trade Commission's May 2025 final affirmative injury determination on antidumping and countervailing duties from Southeast Asia adds another layer of tariffs that SEIA warns will raise costs for the solar products American companies need to build projects. The U.S. Court of International Trade's injunction freezing the elimination of the bifacial exclusion created temporary relief, but legal uncertainty persists. Section 201 tariffs of 14.25% on modules, combined with AD/CVD duties and the Uyghur Forced Labor Prevention Act, create a complex regulatory environment that complicates supply chain planning and increases project costs.
• Grid Connection Constraints and Infrastructure Bottlenecks: North America's bifacial solar market faces significant challenges from grid connection bottlenecks and infrastructure limitations. The 2025 South African Renewable Energy Grid Survey highlighted that developers are ready to build, but grid connection remains the single biggest hurdle to timely delivery, a challenge equally applicable across North American markets. Grid capacity in key regions has been depleted, with projects increasingly competing for limited connection points. The shift in constraint from connection capacity to insufficient load and system flexibility further complicates grid integration, threatening to slow private sector-led growth and creating a "gridlock" that challenges the pace of bifacial technology deployment.

Market Trends

• Technology Transition to N-Type TOPCon Bifacial Modules: North America's bifacial solar market is witnessing a decisive technology transition toward n-type TOPCon bifacial modules, with the technology emerging as the dominant next-generation architecture. TOPCon modules achieve conversion efficiencies exceeding 24% with bifacial gains surpassing 85%, making them particularly suitable for utility-scale power plants. Commercial TOPCon modules have surpassed 22% efficiency to reach a new standard of 22.5% to 24.5% for high-volume products, significantly increasing energy density over older PERC models. Independent testing by NREL and field installations consistently demonstrate 15-25% higher energy yields from N-Type panels compared to P-Type alternatives. Industry projections indicate n-type modules including TOPCon are expected to reach 50% to 60% market share by 2030 and 70% to 80% by 2035.
• Agrivoltaic Expansion and Dual-Use Land Optimization: North America's bifacial solar market is witnessing a transformative trend toward agrivoltaic development, where photovoltaic installations coexist with agricultural activities on the same land. This approach addresses land-use concerns while maximizing bifacial technology's value proposition. Research institutions including NREL and Fraunhofer are advancing agrivoltaic system optimization, with studies examining panel control algorithms and exploring electrification of agricultural uses. The panels offer protection from hail, frost, drought, and heavy rain while generating clean energy.
