Core Viewpoint - The industrial silicon spot prices remained stable over the past week, with minor fluctuations observed in the market, indicating a cautious but improving market sentiment [1]. Supply and Demand Analysis - Supply side: Industrial silicon manufacturers are producing according to plan, with slight production increases from the Southwest region due to some resumption of operations and new capacity coming online [1]. - Demand side: There is an expected increase in operating rates for organic silicon monomer plants in northern regions, which will boost demand for industrial silicon. Additionally, there is a slight increase in operating rates for polysilicon plants, maintaining demand for industrial silicon. Aluminum alloy plants are operating normally, keeping demand stable [1]. Price Dynamics - The overall market for industrial silicon remains under pressure, with prices expected to continue fluctuating within a lower range due to increased supply and limited demand growth. Organic silicon monomer plants are facing inventory pressure, leading to competitive pricing and price declines. The drop in silicon wafer prices has also contributed to a negative sentiment in polysilicon procurement, further impacting prices [1].

Core Viewpoint - Quartz glass fiber, with a silica content exceeding 99.99%, exhibits exceptional thermal resistance and electrical insulation properties, making it suitable for various high-temperature applications in aerospace, military, and semiconductor industries [1][3][5]. Production Process - Quartz glass fiber is produced by refining pure natural crystal into molten quartz glass rods, which are then drawn into fibers. The production methods include hydrogen-oxygen flame and plasma methods, with various coatings applied based on intended use [3][4]. Physical and Chemical Properties - The chemical composition of quartz glass fiber closely resembles that of high-purity quartz glass, resulting in similar physical and chemical properties [4]. - It has superior electrical insulation properties, with the lowest dielectric constant and loss factor among mineral fibers, making it ideal for high-frequency applications [5][6]. Mechanical Properties - Quartz glass fiber has a tensile strength of 6,000 MPa, which is three times that of standard glass fibers. Its tensile modulus and elongation at break are also competitive compared to other fibers [11][12]. Thermal Properties - The softening temperature of quartz glass fiber is 1,700 °C, and it can be used continuously at temperatures up to 1,050 °C. It exhibits minimal weight loss (less than 1.5%) after being subjected to 1,000 °C for 1,000 hours [16][17]. Applications - The superior electrical insulation properties make quartz glass fiber suitable for radar domes in military aircraft, electromagnetic emission windows, and high-frequency circuit boards [20]. - Its thermal resistance allows for applications in aerospace, such as heat-resistant auxiliary facilities around spacecraft engines, thermal protection systems, and ablative materials for re-entry [21].

Core Viewpoint - The article discusses the implementation of the "Distributed Photovoltaic Power Generation Development and Construction Management Measures" issued by the National Energy Administration, emphasizing the need for high-quality development in the distributed photovoltaic industry and the opportunities presented by new policies [3]. Group 1: Definition and Classification - Photovoltaic power generation is the method of converting solar radiation energy directly into electrical energy using solar cells. It is classified into centralized photovoltaic power stations and distributed photovoltaic power generation [5]. - Distributed photovoltaic power generation is developed on the user side, connected to the distribution network, and is generally balanced near the distribution network system [5]. - There are four types of distributed photovoltaic power generation: household use by natural persons, household use by non-natural persons, general commercial and industrial, and large commercial and industrial [6]. Group 2: Types of Distributed Photovoltaic Power Generation - Natural person household use refers to distributed photovoltaic systems built by individuals on their own residential properties, with a connection voltage not exceeding 380 volts. Non-natural person household use involves entities investing in similar systems with a connection voltage not exceeding 10 kV (20 kV) and a total installed capacity not exceeding 6 MW [7]. - General commercial and industrial distributed photovoltaic systems are built on public institutions and commercial buildings, with a connection voltage not exceeding 10 kV (20 kV) and a total installed capacity generally not exceeding 6 MW. Large commercial and industrial systems can connect at 35 kV or 110 kV (66 kV) with higher capacity limits [9]. Group 3: Connection and Capacity Regulations - A project with a connection voltage of 10 kV and an installed capacity of 8 MW does not qualify as general commercial distributed photovoltaic power generation due to exceeding the capacity limit [10]. - A project with a connection voltage of 35 kV and an installed capacity of 5 MW cannot be classified as general commercial distributed photovoltaic power generation [11]. Group 4: Grid Connection Modes - Distributed photovoltaic power generation can adopt three grid connection modes: full grid connection, all self-consumption, and self-consumption with surplus electricity fed into the grid [13]. - Both natural person and non-natural person household uses can choose from the same grid connection modes [14]. - General commercial distributed photovoltaic systems can choose all self-consumption or self-consumption with surplus electricity fed into the grid, while large commercial systems generally must choose all self-consumption [15][16]. Group 5: Project Management and Land Use - Distributed photovoltaic projects must be located within the same land red line as the user’s substation. Large commercial systems can cross land red lines when engaging in dedicated supply [22]. - Projects built on agricultural facilities, such as greenhouses, are classified as agricultural-light complementary projects and fall under centralized photovoltaic management [25]. - Photovoltaic projects built on roads or slopes adjacent to buildings can be managed as commercial distributed photovoltaic systems if they are within the same land red line [26].
