光伏周价格 | 硅料硅片再度报涨，下游博弈持续

Core Viewpoint - The article highlights the recent price increases across various segments of the photovoltaic industry, particularly in polysilicon, silicon wafers, battery cells, and modules, driven by supply-demand dynamics and cost recovery efforts [5][10][19]. Polysilicon Segment - The mainstream transaction prices for N-type polysilicon are reported at 42.0 RMB/KG for re-investment materials, 40.0 RMB/KG for dense materials, and 40.0 RMB/KG for granular silicon [5]. - The overall transaction prices for polysilicon have stabilized around 40 RMB/KG, with an increase in acceptance of price hikes by crystal pulling factories [6]. - As of this week, the polysilicon industry inventory stands at over 370,000 tons, gradually shifting towards crystal pulling factories due to prior stockpiling by specialized silicon wafer manufacturers [7]. - Looking ahead to August, with rising polysilicon prices, some second and third-tier manufacturers in Xinjiang and Qinghai may prepare to resume production, while leading manufacturers also plan to increase output [8][9]. Silicon Wafer Segment - The mainstream transaction prices for N-type silicon wafers are reported at 1.10 RMB/piece for M10, 1.45 RMB/piece for G12, and 1.25 RMB/piece for G12R [10]. - The silicon wafer manufacturers have reduced their operating rates, leading to a balanced supply-demand relationship and noticeable inventory depletion [11]. - Manufacturers with significant low-cost silicon material stock are experiencing profit recovery, and some plan to increase production next month [12]. - The inventory of silicon wafers has entered a depletion phase, with most manufacturers adhering to guided pricing [13]. Battery Cell Segment - The mainstream transaction prices for M10 single crystal TOPCon battery cells are at 0.27 RMB/W, while G12 and G12R cells are at 0.275 RMB/W [16]. - The price increase of 18% for 183N cells is attributed to rising overseas demand, while the price transmission from upstream to downstream remains slow due to intense negotiations [17]. - As of this week, specialized battery cell manufacturers have seen a decrease in inventory, indicating a balanced supply-demand situation [18]. - The price increase for N-type battery cells has been successfully transmitted, but future sustainability depends on the price transmission from modules [19]. Module Segment - The mainstream transaction prices for 182mm double-sided double-glass TOPCon modules are at 0.67 RMB/W, and for 210mm double-sided double-glass HJT modules at 0.72 RMB/W [20]. - Leading manufacturers are maintaining a favorable order intake, while second and third-tier manufacturers face challenges in securing orders, leading to price reductions [21]. - There is an expectation of a gradual price increase of 0.02-0.03 RMB/W from leading manufacturers, while second and third-tier manufacturers are also slightly following suit [22]. - The cost transmission and export tax rebate policies are anticipated to facilitate smoother price adjustments in overseas markets compared to domestic ones [23].
