Solar energy adoption in the Czech Republic has picked up notably in recent years, with both homeowners and businesses turning to photovoltaics as part of the country’s broader energy transition. Behind that growth sits a compact but increasingly professionalised installer market, led by a small group of national holding companies with installed capacity in the hundreds of megawatts.

Industry Overview: Solar PV Installation in the Czech Republic

The Czech Republic’s PV installer market is led by a small group of national holding companies, most founded within a few years of each other between 2010 and 2012, that have each built installed capacity in the range of 130 to 288 MW. The companies in this curated selection reflect that concentration, with the largest players serving both residential and commercial clients across the country.

National Holding Groups

SOLEK HOLDING, headquartered in Prague since 2010, leads the curated selection with the largest installed capacity, reflecting a project portfolio that extends beyond the Czech Republic into wider European and Latin American markets. SOLSOL, based in Brno since 2012, and SOLIDSUN, headquartered in Frýdek-Místek since 2010, follow closely with comparable scale, each having built up capacity through sustained residential and commercial project delivery.

Established Regional Specialists

SOLARTEC HOLDING, based in Rožnov pod Radhoštěm, stands out as the longest-established name on this list, tracing its roots back to 1993 and giving it more than three decades of experience in the Czech solar industry. Solar Global Service, headquartered in Napajedla, rounds out the list, offering both installation and ongoing maintenance and monitoring services to residential and commercial clients.

Market Outlook

With solar adoption continuing to accelerate among both homeowners and businesses in the Czech Republic, competition among the established national holding groups is likely to intensify, while newer entrants compete on regional relationships and service quality. Continued growth in commercial and industrial demand for on-site generation is a trend worth watching as the market develops further.
