Core Insights - The U.S. photovoltaic (PV) market is experiencing a dual turning point of "demand explosion + capacity return" in 2025, driven by AI computing power expansion and a declining interest rate cycle, leading to a projected installation capacity of over 60GW in 2025 with a compound annual growth rate of 20% [1][2]. Demand Side - The U.S. renewable energy generation share is low at approximately 10%, significantly below the global average of 30%, indicating substantial room for energy structure transformation [2]. - The demand for PV is catalyzed by the electricity gap created by AI data centers and manufacturing recovery, as these centers operate continuously and require stable power sources, making PV a preferred clean energy option [2]. - The arrival of a declining interest rate cycle has amplified demand potential, as the internal rate of return (IRR) for PV projects is highly correlated with interest rates, leading to lower financing costs and increased investment willingness from developers [2]. Policy Support - The U.S. government is promoting domestic PV production through a combination of "manufacturing subsidies + trade protection," establishing a solid foundation for local capacity expansion [2]. - Although the Investment Tax Credit (ITC) for distributed projects will gradually phase out after 2027, subsidies for manufacturing remain strong, with 4 cents per cell and 7 cents per module, reducing cost pressures for domestic manufacturers [2]. Domestic Capacity and Challenges - The planned domestic PV capacity in the U.S. is set to reach 60-70GW, with approximately 40GW already in production for modules, but only single-digit capacity for cells, highlighting a significant supply gap [3]. - The U.S. PV manufacturing faces challenges such as high labor, energy, and compliance costs compared to China, necessitating the adoption of more efficient and lower-cost technologies like HJT (Heterojunction Technology) [3][4]. HJT Technology Advantages - HJT technology requires only four core processes, resulting in lower operational costs (OPEX) of $5.4-5.5 million per GW, compared to $7.2 million for TOPCon technology, with a cost difference of 2 cents per watt [4]. - Even without government subsidies, HJT can achieve a profit of 1.6 cents per watt, indicating sustainable profitability post-subsidy reduction [5]. Patent Landscape - HJT technology has a patent advantage, as its core patents expired in 2015, allowing U.S. companies to expand capacity without the risk of patent litigation, unlike TOPCon and BC technologies [8]. - Several U.S. companies have announced HJT capacity expansion plans, totaling over 30GW, expected to materialize between 2026 and 2028, providing certainty for the supply chain [8][9]. Equipment Supply Chain - The surge in HJT capacity in the U.S. will benefit Chinese equipment manufacturers, who dominate the global HJT equipment market with over 70% market share, providing a competitive edge in terms of cost and service [10]. - U.S. companies prefer Chinese equipment due to significant cost advantages (60%-70% cheaper than overseas options) and faster service response times, which are crucial for meeting rapid production ramp-up needs [10]. Investment Opportunities - The expansion of domestic PV capacity and the adoption of HJT technology create clear investment themes focused on "equipment leaders + technology support," balancing performance certainty with growth potential [11]. - Key players include: - Maiwei Co., which leads in HJT equipment with over 70% market share, benefiting from U.S. capacity expansion [11]. - Aotwei, a leader in module packaging equipment, with ongoing demand from the 40GW of installed capacity [11]. - Gaomei Co., a core supplier of HJT wafer cutting equipment, benefiting from technology upgrades and U.S. capacity expansion [11]. Auxiliary Investment Themes - The demand for low-temperature silver paste and TCO targets will rise with HJT technology, driving exports of related materials [12]. - Companies producing photovoltaic glass and encapsulants are well-positioned to meet the supply chain needs of U.S. module production, leveraging global presence and cost advantages [12].

Core Viewpoint - The U.S. photovoltaic (PV) market is expected to experience a "demand explosion + capacity return" by 2025, driven by AI computing power expansion and a declining interest rate cycle, leading to a projected installation capacity of over 60GW in 2025 with a compound annual growth rate of 20% [5][6]. Demand Side - The share of renewable energy generation in the U.S. is approximately 10%, significantly lower than the global average of 30%, indicating substantial potential for energy structure transformation [7]. - The demand for PV is catalyzed by the electricity needs of AI data centers and the recovery of the manufacturing sector, as these facilities operate continuously and require stable energy sources, making PV an attractive option [7]. - The arrival of a declining interest rate cycle enhances the demand potential, as the internal rate of return (IRR) for PV projects is closely linked to interest rates, leading to lower financing costs and increased investment willingness from developers [8]. Policy Side - The U.S. government is promoting domestic PV industry localization through a combination of manufacturing subsidies and trade protection measures. Although the Investment Tax Credit (ITC) for distributed projects will gradually be phased out after 2027, subsidies for manufacturing continue to support the industry [9]. - Current domestic PV capacity planning in the U.S. is set at 60-70GW, with approximately 40GW of component capacity already in operation, but a significant gap remains in battery cell production, highlighting a structural imbalance in the industry [9]. Manufacturing Challenges - U.S. PV manufacturing faces three main pressures: high labor costs, high energy consumption, and high compliance costs, necessitating the adoption of more efficient and lower-cost technology solutions [10]. - The cost structure for U.S. manufacturing is significantly higher than that of China, with labor costs being 3.5 times higher, energy costs 2.1 times higher, and depreciation costs 1.3 times higher [11]. - The shift in market focus from capital expenditure (CAPEX) to operational expenditure (OPEX) favors technologies like Heterojunction Technology (HJT), which offers superior operational efficiency compared to traditional technologies [11]. HJT Technology Advantages - HJT technology has a unique advantage in the U.S. market due to its lack of patent barriers, as its core patents expired in 2015, allowing companies to avoid patent litigation risks [15]. - The recognition of HJT technology has led to substantial capacity expansion plans, with several U.S. companies announcing HJT capacity increases totaling over 30GW by the end of 2025 [15]. Chinese Equipment Suppliers - The expansion of HJT capacity in the U.S. will benefit Chinese PV equipment manufacturers, who hold a dominant position in the global market, particularly in HJT production line equipment [18]. - Chinese equipment suppliers, such as Maiwei, have over 70% market share in HJT equipment, providing a cost-effective solution that meets U.S. environmental and technical standards [18]. - The competitive advantages of Chinese equipment include lower prices (60%-70% of overseas equipment) and faster service response times, making them the preferred choice for U.S. manufacturers [18]. Investment Focus - The clear investment theme emerging from the U.S. PV market expansion and HJT technology adoption focuses on "equipment leaders + technology support," balancing performance certainty with growth potential [19]. - Key players include Maiwei, a leader in HJT equipment with significant market share, and Aotwei, a leader in component packaging equipment, both of which are well-positioned to benefit from the ongoing capacity expansion [20]. - Supporting lines of investment include materials and technology companies that supply low-temperature silver paste and TCO targets, which are essential for HJT technology [21].
