尽管美国总统特朗普取消了对可再生能源开发商的补贴和税收减免，这一举措使美国太阳能发电装机容量的增长放缓，但并未完全脱轨。 能源数据门户网站Cleanview的数据显示，截至2025年上半年，美国公用事业规模的太阳能系统装机容量同比增长约10%。这一增速远低于2024年的33%以及 自2015年以来29%的年均增速。然而，考虑到特朗普政府对可再生能源的强烈反对立场，以及因此给电力开发商带来的政策不确定性，今年装机容量依然有 所增加，这一事实将被清洁能源倡导者视为一项胜利。 佛罗里达州的数据同样令人担忧，该州是美国第三大太阳能市场。从表面上看，今年迄今的扩张统计数据似乎不算太差，装机容量同比增长8%，达到接近 12,000兆瓦的历史新高。然而，自1月以来，该州新增的公用事业规模太阳能装机容量为零，这表明自特朗普重新上任以来，该州公用事业公司扩大太阳能 发电的工作可能已完全停止。 北卡罗来纳州和内华达州——这两个州均位列太阳能装机容量前十——以及排名第15位的新墨西哥州的太阳能发电扩张工作也几乎陷入停滞。 整体形势 在其他地方的低迷基调中，亚利桑那州的持续进展在一定程度上起到了缓冲作用。作为美国太阳能装机容量第五大 ...

Core Viewpoint - The article discusses the significant negative impact of President Trump's tax bill on the U.S. clean energy sector, particularly the solar energy industry, leading to a sharp decline in stock prices of major renewable energy companies [1][4]. Tax Credit Reductions - The new bill drastically cuts the tax incentives for clean energy that were previously established under the Biden administration's Inflation Reduction Act. The residential solar tax credit will be eliminated by the end of 2025, while the commercial solar tax credit will gradually decrease starting in 2029, ultimately being phased out by 2032 [4][5]. - The bill also introduces a critical change by disallowing solar leasing companies from applying for the commercial investment tax credit (ITC), which could have catastrophic effects on the rooftop solar industry, where approximately 70% of installations are based on leasing [5][6]. Impact on Companies - Major companies in the solar sector experienced significant stock price declines following the announcement of the bill. NextEra Energy's stock fell by 6.4%, Enphase Energy's by 19.6%, SolarEdge's by approximately 25%, and Sunrun's by 37% [1][4]. - Analysts predict that green energy stocks may continue to decline, with the Invesco Solar ETF seeing a net asset value drop of 7.45% [6]. Senate Considerations - The Senate is expected to develop its own proposal, with some Republican senators expressing concerns about the elimination of energy tax credits. However, analysts believe that these dissenting voices may not lead to substantial changes in the final legislation [7][8]. - The bill is projected to increase the national debt by approximately $3.8 trillion over the next decade, raising concerns about fiscal responsibility among lawmakers [7]. Political Dynamics - President Trump has urged the Senate to act quickly on the bill, indicating potential political repercussions for Republican senators who oppose it. This pressure may lead to a lack of substantial opposition in the Senate [8].

Core Viewpoint - The recent tax bill passed by the U.S. House of Representatives imposes harsher cuts to tax credits for the clean energy sector than anticipated, leading to a significant decline in the stock prices of renewable energy companies [1][3]. Group 1: Impact on Renewable Energy Companies - NextEra Energy, the largest renewable energy developer in the U.S., saw its stock price drop by 6.4% following the announcement of the tax bill [1]. - Enphase Energy, which produces solar systems and battery technologies, experienced a stock loss of 19.6% [1]. - SolarEdge, an inverter and battery supplier, saw its stock shrink by approximately 25% [1]. - Sunrun, a residential solar company, faced a dramatic stock decline of 37% [1]. Group 2: Changes to Tax Credits - The new bill significantly reduces tax incentives for clean energy compared to the Biden administration's Inflation Reduction Act, with residential solar tax credits set to be eliminated by the end of 2025 and commercial solar tax credits gradually decreasing starting in 2029 [3][4]. - The residential solar tax credit, which currently offers a 30% federal tax credit, will be fully phased out by 2032, while commercial tax credits will drop to 80% in 2029, 60% in 2030, 40% in 2031, and be eliminated by 2032 [3][4]. Group 3: Implications for Solar Leasing - A critical new provision in the bill prohibits solar leasing companies from applying for commercial investment tax credits (ITC), which could have catastrophic effects on the rooftop solar industry, where approximately 70% of installations use leasing models [4]. - Analysts have indicated that this change could signify the end of the residential solar business in the U.S. [4]. Group 4: Changes in Project Qualification Standards - The qualification criteria for commercial project tax credits have shifted from a "construction begins" standard with a four-year safe harbor to a "placed in service" standard, eliminating the grace period [5]. - This adjustment particularly impacts utility-scale projects, which require longer construction timelines, leading to declines in related solar stocks [5]. Group 5: Market Reactions and Future Outlook - The Invesco Solar ETF, which tracks U.S. solar companies, saw a net asset value decline of 7.45% following the announcement [5]. - Analysts have warned that green energy stocks may continue to decline as the implications of the tax bill unfold [5]. - The overall sentiment among analysts is that there is currently no compelling reason to hold U.S. solar company stocks due to the government's focus on eliminating green subsidies [6].
