BRUSSELS (Reuters) -The European Union's expansion of solar energy is on track for its first annual slowdown in more than a decade, industry data showed on Thursday, as some governments reduce subsidies for rooftop solar panels.
The trend reflects shifting political priorities in Europe as some member countries have scaled back green measures or support for clean energy from budgets stretched by spending on defence and local industries.
The EU is on track to install 64.2 gigawatts of new solar energy capacity in 2025, a 1.4% fall from the 65.1GW installed last year, industry association SolarPower Europe said.
"There's a kind of paralysis. There's still interest, but people aren’t making decisions," said Peter Knuth, managing director of German photovoltaic systems installation company enerix.
Early purchases in 2022 and 2023, along with rising interest rates, and economic uncertainty have contributed to the falling demand, not falling electricity prices, Knuth added.
The year-on-year drop would mark the first time since 2015 that the growth of Europe's solar market has slowed - denting an area of fast progress in Europe's shift to clean energy. Solar capacity growth soared by 51% in 2023, although last year growth had already slowed to 3%.
Last month, solar generated 22% of total EU electricity, making it the EU's largest single source of power generation that month.
But current deployment rates now indicate the EU will fall short, by about 27GW, of the 750GW of solar capacity which SolarPower Europe said is needed by 2030 for the EU's climate targets and plans to phase out Russian energy.
The main cause of the slowdown is fewer residential rooftop solar panel installations - a sector that is set to make up 15% of total new capacity this year, halving the roughly 30% share it held over 2020 to 2023.
Germany and France are among the countries reducing their feed-in tariff payments for rooftop solar energy, while the Netherlands is also reducing support for households that export their excess solar power to the grid.
Misleading communication regarding a law passed by the previous German government in February cancelling compensation for solar power grid during peak times along with changes to the renewable heating law had also hit demand, Knuth said.
The new German government's plans to reassess the need for renewables and promises of an expansion of gas power plants are also not helping, he said.
The German Economy Ministry was not immediately available to comment on the data.
Asked what the German government could do to help the market, Knuth said: "Best to stay quiet. Honestly. The endless debate about renewable energy ... is counterproductive."

Solar energy is the energy harnessed from the sun's rays, which can be converted into electricity or heat for various applications.
Renewable energy is energy derived from natural sources that are replenished at a faster rate than they are consumed, such as solar, wind, and hydro.
Solar capacity refers to the maximum amount of electricity that can be generated by solar panels at a given time, typically measured in gigawatts (GW).
Feed-in tariffs are payments made to energy producers for the electricity they generate and feed into the grid, often used to promote renewable energy.
