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].

Report Industry Investment Rating - Unilateral: Neutral for polysilicon; short - term range operation for polysilicon [5][7] - Inter - period: None for both industrial silicon and polysilicon [2][5][7] - Inter - commodity: None for both industrial silicon and polysilicon [2][5][7] - Spot - futures: None for both industrial silicon and polysilicon [2][5][7] - Options: None for both industrial silicon and polysilicon [2][5][7] Core View - Industrial silicon's short - term supply - demand fundamentals are average. The intraday sharp rise and then fall of the industrial silicon futures are mainly affected by the rise of coking coal. The short - term industrial silicon futures are affected by the overall commodity sentiment and policy - related news. If there are policies to promote, the futures may have room to rise as the current valuation is low [2] - The supply - demand fundamentals of polysilicon are average. The current futures are affected by the anti - involution policy and weak reality. The policy is still in progress, and the futures fluctuate greatly. In the medium - to - long - term, it is suitable to go long on polysilicon at low prices [7] Market Analysis Industrial Silicon - On September 15, 2025, the industrial silicon futures price was strong. The main contract 2511 opened at 8,725 yuan/ton and closed at 8,800 yuan/ton, up 0.86% from the previous settlement. The position of the main contract 2511 was 290,948 lots, and the number of warehouse receipts was 49,905 lots, down 93 lots from the previous day [1] - The spot price of industrial silicon rose slightly. The price of East China oxygen - passing 553 silicon was 9,100 - 9,300 yuan/ton, and 421 silicon was 9,400 - 9,600 yuan/ton.

The monomer factory's pre - sales orders were sufficient, and the inventory pressure was not large. Downstream enterprises' procurement rhythm remained unchanged, mainly replenishing stocks at low prices, with limited support for the market. Silicone is expected to stabilize in the short term [1] Polysilicon - On September 15, 2025, the main contract 2511 of polysilicon futures fluctuated. It opened at 53,630 yuan/ton and closed at 53,545 yuan/ton, down 0.34% from the previous trading day. The position of the main contract was 132,212 lots (134,898 lots the previous day), and the trading volume was 237,981 lots [4] - The spot price of polysilicon remained stable. The price of N - type material was 49.10 - 54.00 yuan/kg, and n - type granular silicon was 48.00 - 49.00 yuan/kg. The inventory of polysilicon manufacturers increased, and the inventory of silicon wafers decreased. The latest polysilicon inventory was 21.90 (a month - on - month change of 3.79%), the silicon wafer inventory was 16.55GW (a month - on - month change of - 1.78%), the weekly polysilicon output was 31,200 tons (a month - on - month change of 3.31%), and the silicon wafer output was 13.88GW (a month - on - month change of 0.73%) [4] - The price of domestic N - type 18Xmm silicon wafers was 1.33 yuan/piece (up 0.05 yuan/piece), N - type 210mm was 1.68 yuan/piece (up 0.05 yuan/piece), and N - type 210R silicon wafers were 1.43 yuan/piece (up 0.05 yuan/piece) [4] - Silicon wafer enterprises may raise prices. N - type silicon wafers - 183mm may rise to 1.35 yuan/piece, N - type silicon wafers - 210R to 1.45 yuan/piece, and N - type silicon wafers - 210mm to 1.7 yuan/piece. The price increase of 183mm is likely to be accepted by downstream, while the other two sizes need to pay attention to the transaction situation [6] - The price of high - efficiency PERC182 battery cells was 0.27 yuan/W, PERC210 battery cells were about 0.28 yuan/W, TopconM10 battery cells were about 0.32 yuan/W (up 0.01 yuan/W), Topcon G12 battery cells were 0.31 yuan/W (up 0.01 yuan/W), Topcon210RN battery cells were 0.29 yuan/W, and HJT210 half - cell battery was 0.37 yuan/W [6] - The mainstream transaction price of PERC182mm components was 0.67 - 0.74 yuan/W, PERC210mm was 0.69 - 0.73 yuan/W, N - type 182mm was 0.67 - 0.69 yuan/W, and N - type 210mm was 0.67 - 0.69 yuan/W [6] Strategy Industrial Silicon - The spot price rose slightly following the futures. The short - term supply - demand fundamentals are average. The short - term industrial silicon futures are affected by the overall commodity sentiment and policy - related news. Attention should be paid to whether there are policies for capacity withdrawal. If there are policies to promote, the futures may have room to rise [2] Polysilicon - The supply - demand fundamentals are average. The current futures are affected by the anti - involution policy and weak reality. Participants should pay attention to risk management. They need to continuously follow up on the implementation of policies and the downward transmission of spot prices. In the medium - to - long - term, it is suitable to go long on polysilicon at low prices. Short - term range operation is recommended [7]
