Industry Investment Rating - No investment rating information provided in the report Core Viewpoints - The silicon price has declined and adjusted due to the cooling of sentiment and hedging pressure above the market, but recently the bullish sentiment has resurfaced, and it is expected that the silicon price may maintain a high - level and strong consolidation. For polysilicon, since the end of June, driven by supply - side reform expectations and spot price increases, the polysilicon market has continued to rise, and although the sentiment has faded recently, it still fluctuates, with prices remaining high and volatile, requiring cautious operation [1] Summary by Relevant Catalogs Price Information - **Industrial Silicon Spot Price**: The average price of non - oxygen - blown 553 in different regions (East China, Huangpu Port, Tianjin Port, Kunming, Sichuan) remained unchanged at 9,200 yuan/ton, 9,300 yuan/ton, 9,100 yuan/ton, 9,250 yuan/ton, and 8,950 yuan/ton respectively; the average price of oxygen - blown 553 in different regions remained unchanged; the average price of 421 in different regions also remained unchanged [1] - **Industrial Silicon Futures Price**: The closing price of the futures main contract was 8,840 yuan/ton, a decrease of 1.78% from the previous day [1] - **Polysilicon Spot Price**: N - type dense material, N - type re - feeding material, N - type mixed material, and N - type granular silicon prices remained unchanged at 46 yuan/kg, 47 yuan/kg, 45 yuan/kg, and 44.5 yuan/kg respectively [1] - **Polysilicon Futures Price**: The closing price of the futures main contract was 51,800 yuan/ton, a decrease of 2.24% from the previous day [1] - **Silicon Wafer Price**: The prices of N - type 210mm, N - type 210R, and N - type 183mm silicon wafers remained unchanged at 1.55 yuan/piece, 1.35 yuan/piece, and 1.20 yuan/piece respectively [1] - **Battery Chip Price**: The price of single - crystal PERC battery chips M10 - 182mm remained unchanged at 0.27 yuan/watt [1] - **Component Price**: The prices of single - sided and double - sided single - crystal PERC components of different specifications remained unchanged [1] - **Organic Silicon Price**: The prices of DMC, 107 glue, and silicone oil remained unchanged at 12,000 yuan/ton, 12,750 yuan/ton, and 14,100 yuan/ton respectively [1] News and Information - Yantai Huaxing Silicon Materials Co., Ltd. was established, jointly held by Xingfa Group and Wanhua Chemical, marking the deepening of their strategic cooperation in the silicon materials field [1] - Shifang Baichuan Xinyong New Energy Co., Ltd. is promoting its high - efficiency perovskite solar cell production project, planning to build two pilot production lines, with a design annual output of 1.4GW of high - efficiency silicon solar cells and an expansion of perovskite tandem solar cell production capacity to 200MW/year [1] Investment Strategy - Industrial Silicon - **Supply Side**: As the silicon price continues to rise, some previously overhauled silicon plants in Xinjiang have resumed production. In addition, the southwest production area has entered the wet season, with lower electricity costs and a steady increase in enterprise start - up rates. It is expected that some silicon furnaces will restart in August, and the supply will increase steadily [1] - **Demand Side**: Polysilicon enterprises maintain a production - reduction state, and some silicon material plants have复产 arrangements, which will bring some demand increments; in the organic silicon sector, a large factory has stopped production for rectification due to an accident, resulting in a temporary tightening of supply, but recently the monomer plants have recovered, increasing market supply pressure and potentially pressuring prices again; silicon - aluminum alloy enterprises purchase as needed, and the downstream's willingness to stock up at low levels is insufficient [1] Investment Strategy - Polysilicon - **Supply Side**: Polysilicon enterprises maintain a production - reduction state, and some may have new production capacity put into operation. After offsetting the increase and decrease, the output is expected to increase slightly. It is expected that the output in July will approach 110,000 tons, and the output in August will increase to about 130,000 tons month - on - month [1] - **Demand Side**: The photovoltaic market is generally weak, with rising inventories of silicon wafers and silicon materials. Recently, due to the expected increase in polysilicon prices, the downstream silicon wafer prices have followed suit, and the trading atmosphere has improved. However, the terminal market is still weak due to the large over - consumption of demand in the first half of the year [1]
