光伏行业周报（20250512-20250518）

Investment Rating - The report maintains a "Recommendation" rating for the photovoltaic industry [1] Core Viewpoints - In April, India's photovoltaic installations saw a significant year-on-year increase, with a total of 10.08 GW added from January to April 2025, representing an 8% increase year-on-year. April alone saw 2.30 GW added, a remarkable 179% increase year-on-year, although it was a 25% decrease month-on-month. The Indian government aims for a cumulative installed capacity of 280 GW by 2030, with an annual addition of approximately 30 GW, supported by various policies and subsidies [6][10] - The demand in the downstream market has weakened, leading to a slight decrease in photovoltaic glass prices. The average price for 3.2mm coated photovoltaic glass is reported at 21.50 CNY/m², down 1.1% week-on-week, while the 2.0mm variant is at 13.50 CNY/m², down 1.8% week-on-week. The industry inventory days have increased to approximately 38.2 days, indicating a trend of rising inventory levels [6][12] Summary by Sections Section 1: April India's Photovoltaic Installations - April saw a year-on-year increase in India's photovoltaic installations, with a total of 2.30 GW added, marking a 179% increase year-on-year [10] - The cumulative installed capacity from January to April 2025 reached 10.08 GW, an 8% increase year-on-year [10] - The Indian government's National Electricity Plan aims for a cumulative installed capacity of 280 GW by 2030, with annual additions of about 30 GW [10] Section 2: Market Trends - The photovoltaic industry experienced a slight decrease in glass prices due to weakened downstream demand and increased production capacity [12] - The average price for 3.2mm coated photovoltaic glass is 21.50 CNY/m², down 1.1% week-on-week, while the 2.0mm variant is at 13.50 CNY/m², down 1.8% week-on-week [12] - Industry inventory days have increased to approximately 38.2 days, indicating a trend of rising inventory levels [12] Section 3: Industry Chain Prices - The average price for polysilicon dense material is reported at 37.00 CNY/kg, down 5.1% week-on-week, while the price for polysilicon granular material remains stable at 35.00 CNY/kg [39] - The average price for 182-183.75mm monocrystalline N-type silicon wafers is 0.95 CNY/piece, down 5.0% week-on-week [41] - The average price for 182-183.75mm TOPCon battery cells is reported at 0.260 CNY/W, down 1.9% week-on-week [44]
