Czechia Ends Double Tax on Solar Batteries

Getting taxed twice for choosing clean energy never made sense, and Czech lawmakers finally agree.

Czechia's Economic Committee just backed proposals to stop double taxation on solar installations with battery storage. The committee also supported raising the electricity tax threshold from 50 kW to 100 kW, giving more solar owners a break.

For years, adding a battery to a solar power plant meant getting hit with taxes twice—once for the solar panels and again for the storage system. Jan Krčmář, executive director of Solární Asociace (the Czech solar association), worked with the current government to fix this unfair practice since they took office.

"The Ministry of Industry as well as the Finance Ministry both agreed," Krčmář told PV Magazine. Working alongside Czech battery association AKU-BAT CZ, his team crafted language that sailed through the economic committee.

The proposals still need to pass second and third readings in parliament, then head to the senate. But Krčmář feels confident the law will pass later this year and take effect in 2026.

The Ripple Effect

Czechia is already experiencing a solar boom. The country installed 696 MW of new solar capacity in 2025, bringing total capacity to around 5.5 GW.

These tax changes arrive alongside other clean energy wins. Last year, Czechia expanded rules for agrivoltaics (combining farming with solar panels) and increased the limit for mandatory electricity generation licenses.

Together, these policies make solar power more accessible for households and businesses ready to cut their electricity bills and carbon footprint. Removing double taxation on battery storage means people can store their own clean energy without financial penalty.

Battery storage transforms solar from a daytime-only power source into round-the-clock clean energy. When governments remove tax barriers instead of creating them, everyone wins—families save money, businesses grow, and the planet gets cleaner air.

One small tax change today could light up thousands of Czech homes with stored sunshine tomorrow.
