Solar feed-in in Germany up 33% in September; renewables up 9.5% year to date

01The Story新闻事实

An IWR analysis of ENTSO-E data shows German solar feed-in rose 33.0% to 8.55 billion kWh in September 2026, driven by sunny weather and continued photovoltaic expansion. Wind and hydropower feed-in fell year on year. Renewables supplied 209.88 billion kWh from January to September, up 9.5%, reaching a 63.7% share of total feed-in.IWR对ENTSO-E数据的分析显示，受晴朗天气和光伏持续扩张推动，2026年9月德国太阳能并网电量增长33.0%，达85.5亿千瓦时。风电和水电并网量同比下降。1至9月可再生能源供电2098.8亿千瓦时，增长9.5%，占总并网电量的63.7%。

Wind power feed-in fell 6.7% to 11.31 billion kWh; hydropower (excluding pumped storage) fell 33.1% to 0.81 billion kWh.风电并网量下降6.7%至113.1亿千瓦时；水电（不含抽水蓄能）下降33.1%至8.1亿千瓦时。
Renewables fed in 209.88 billion kWh from January to September 2026, up 9.5% from 191.71 billion kWh a year earlier.2026年1至9月可再生能源并网2098.8亿千瓦时，较上年同期的1917.1亿千瓦时增长9.5%。
The renewables share of total feed-in was 63.7% (January–September 2025: 62.3%).可再生能源占总并网电量比例为63.7%（2025年1至9月为62.3%）。
September saw around 192 sunshine hours nationwide, about 28% above the 1961–1990 average, and a mean temperature of 15.9 °C, roughly 2.6 degrees above that baseline.9月全国日照约192小时，比1961–1990年平均值高约28%；平均气温15.9°C，比该基准高约2.6度。
Hard coal feed-in rose 12.5% to 22.74 billion kWh year to date, while lignite fell 1.9% to 48.52 billion kWh.年初至今硬煤并电量增长12.5%至227.4亿千瓦时，褐煤下降1.9%至485.2亿千瓦时。

Germany's renewable electricity supply is growing fast enough that even a month of weaker wind and hydropower still left renewables up 3.8% year on year, with solar expansion and weather driving the mix shift.德国可再生能源电力供应增长迅速，即使在风电和水电走弱的月份，可再生能源仍同比增长3.8%，太阳能扩张和天气因素正在推动电力结构转变。

04What to Watch后续关注

Whether solar feed-in growth continues as photovoltaic capacity expands through the rest of 2026.随着光伏装机在2026年剩余时间继续扩张，太阳能并网量增长能否持续。
Whether wind and hydropower feed-in recover from their below-prior-year September levels.风电和水电并网量能否从低于上年同期的9月水平回升。
Whether the renewables share of total feed-in continues to climb above 63.7% in the final quarter.第四季度可再生能源占总并网电量的比例能否继续攀升并超过63.7%。

05Uncertainties不确定因素

The ENTSO-E-based figures are preliminary (as of October 1, 2026) and exclude own consumption, so they may differ from official gross generation statistics such as Eurostat's.基于ENTSO-E的数据为初步数据（截至2026年10月1日），且不含自用电量，因此可能与Eurostat等官方总发电量统计存在差异。
Weather-driven monthly swings mean September's solar surge may not indicate a sustained monthly growth rate.天气导致的月度波动意味着9月太阳能激增可能不代表持续的月度增速。
