光伏周价格 | 库存承压与需求疲软共振，各环节价格延续下行通道

Core Viewpoint - The photovoltaic industry is experiencing a downward price trend across multiple segments, driven by oversupply and weak demand, leading to significant price reductions in polysilicon, wafers, cells, and modules [4][10][14]. Polysilicon - Supply side: The polysilicon industry maintains high inventory levels above 510,000 tons, with a slight accumulation trend, indicating a continued oversupply situation. Increased production from overseas and domestic second and third-tier companies adds pressure on leading polysilicon manufacturers [4]. - Demand side: Continuous price declines in the downstream wafer segment are causing cost losses for wafer manufacturers, which in turn pressures polysilicon suppliers to lower prices. Current mainstream transaction prices are approaching RMB 45/kg, with some traders selling at as low as RMB 38/kg. The market anticipates further declines to around RMB 40/kg [5]. - Price trend: Polysilicon prices have entered a downward phase, with expectations of further price drops due to strong downward pressure from both low-priced sources and aggressive pricing strategies from downstream buyers [5][6]. Wafers - Supply side: The industry inventory has exceeded 27 GW, with significant production increases from wafer manufacturers, leading to a situation of oversupply [7]. - Demand side: The production increase in the downstream cell segment has not kept pace with wafer expansion, resulting in insufficient demand to absorb the high inventory levels [8]. - Price trend: Due to pressure from inventory and aggressive pricing from second and third-tier manufacturers, wafer prices are expected to continue declining, with current lowest prices at RMB 1.00 for 183mm and RMB 1.10 for 210R types [9]. Cells - Supply side: The inventory level in the cell segment has remained above one week, with slower-than-expected inventory reduction, leading to increasing pressure on manufacturers [10]. - Demand side: The upcoming adjustment of export tax rebate policies has heightened caution among overseas customers, slowing down order placements. Domestic demand has not effectively supported the market, leading to a cautious purchasing strategy among buyers [11]. - Price trend: Major manufacturers have reduced prices to around RMB 0.41/W, with some market prices dropping to RMB 0.40/W. The significant drop in raw material costs has weakened the cost support for cell prices, indicating a risk of further declines [12]. Modules - Supply side: Leading companies are attempting to maintain price levels through firm quotations, while second and third-tier manufacturers are adopting aggressive sales strategies, intensifying competition in the market [14]. - Demand side: Anticipation of changes in export tax policies has cooled overseas demand, with domestic customers showing low acceptance of current high prices. Previous procurement prices from state-owned enterprises are suppressing current market price acceptance [15]. - Price trend: There is a divergence between high quotations and low transaction volumes, with actual transaction prices for leading companies falling below RMB 0.80/W. The combination of declining upstream cell prices and reduced demand is expected to lead to further decreases in module prices [16].
