美国光伏股已现“黄金坑”？高盛：超级大规模计算中心正在改写电网需求逻辑

Group 1 - The core viewpoint of the report is that the solar photovoltaic (PV) sector is entering a structural investment window, driven by the surge in electricity demand from data centers, which is reshaping the growth logic of the U.S. power grid [1][2] - Solar PV is expected to account for approximately 54% of new power generation capacity added in the U.S. by 2025, highlighting its central role in the transition of the U.S. power structure [1] - The current valuation of U.S. solar stocks is significantly below historical highs and shows a clear discount compared to other power sector themes, making utility-scale solar companies particularly attractive for investors [1][4] Group 2 - Goldman Sachs has raised its forecast for U.S. electricity demand growth from 2.5% to 2.6% annually, primarily driven by strong demand from data centers, which are expected to contribute about 120 basis points to growth by 2030 [2] - To meet future electricity demands from data centers, approximately 82 gigawatts (GW) of new generation capacity will be needed by 2030, with solar PV expected to contribute around 21 GW of this new capacity [2] - The utility-scale solar installation capacity in the U.S. is projected to grow by about 3% year-on-year in 2026, reaching approximately 40 GW, while the residential solar market is expected to face a decline of about 20% due to the expiration of tax incentives [3] Group 3 - Despite a rebound from early 2025 lows, the valuation levels of U.S. solar stocks remain attractive, with utility-scale solar companies trading at a price-to-earnings ratio significantly below the overall power sector and market averages [4] - The current valuation levels may provide investors with an opportunity to enter the U.S. power structure transition theme at a relatively low cost, considering the advantages of solar PV in terms of generation costs and deployment speed compared to new natural gas and nuclear projects [4]
