   • 2025 July 24, Will Mathis, “Europe's Solar Power Growth Set to Dip for First Time Since 2016”, in BloombergNEF‎^[1], archived from the original on 24 July 2025:

     The European Union's string of record-setting solar power deployment is on track to come to an end this year as demand wanes for rooftop solar panels due to lower wholesale electricity prices. Solar power additions are set to contract 1.4% in the EU, the first annual dip since 2016, according to a report from industry group Solar Power Europe. While new additions are still at historically high levels, it shows the impact on growth of saturated solar power markets where prices regularly dip below zero during the sunniest parts of the year. Overall, the EU is on track to add 64.2 gigawatts of new capacity, according to the industry group. That view contrasts with analysis from BloombergNEF that sees slight growth this year in the bloc.
