Czechia deployed 696MW of new solar PV capacity in 2025, according to data released by the country’s solar industry body, Solární Asociace. The figure represents a decline from the 967MW installed in 2024 and brings the country’s cumulative installed solar capacity to around 5.5GW.
Solární Asociace attributed the year-on-year slowdown primarily to weaker activity in the residential solar segment. In 2025, there were 17,391 fewer residential rooftop installations than in the previous year, with the segment adding a total of 251MW. The association said the decline was driven by repeated pauses and reductions in subsidy schemes, combined with lower electricity prices, which reduced the attractiveness of small-scale PV investments.
Despite the residential slowdown, the commercial and industrial (C&I) segment remained Czechia’s largest source of new capacity. The segment added 370MW in 2025 across approximately 3,000 projects. While C&I solar continues to benefit from financial incentives, Solární Asociace noted that many projects were delayed due to administrative issues linked to the subsidy system.
“These issues were subsequently resolved and we expect strong growth this year as well,” said Jan Krčmář, executive director of Solární Asociace.
Utility-scale solar accounted for a smaller share of new capacity, with around 75MW deployed in 2025 across roughly 25 projects. To stimulate further growth in this segment, Solární Asociace has recommended the introduction of solar auctions with procurement volumes in the low hundreds of megawatts, which would offer investors more predictable and stable cashflows.
Uncertainty remains over whether Czechia’s solar market will rebound in 2026, as the country’s new government has yet to clarify its policy stance on PV subsidies. Solární Asociace has urged the government to stabilise the rooftop market through renewed support for residential and C&I installations. Over the longer term, the association has also suggested a shift towards alternative financial mechanisms, such as zero-interest loans or faster depreciation schedules, to allow the sector to grow more independently of subsidy cycles.
“We might see similar numbers to last year, but if subsidies for rooftop solar are cut, we could see a significant slowdown,” Krčmář said. “At the same time, we expect several dozen medium-sized ground-mounted projects to come online this year. In the longer term, there are gigawatts of utility-scale projects in the pipeline, but these are currently being held back by solar PV economics and permitting challenges.”
While solar deployment slowed in 2025, Czechia’s energy storage market showed signs of accelerating growth. A total of 546MWh of battery storage capacity was connected last year, representing an 8% increase year on year. According to Solární Asociace, distribution companies have already received connection requests for an additional 350GWh of battery capacity.
