Spain’s abundant sunshine has made it one of Europe’s leading solar markets, with installed capacity surpassing 32 GW and expected to exceed 150 GW by 2035. Behind that expansion sits an installer landscape that ranges from integrated national utilities enabling hundreds of thousands of self-consumption connections, to regional specialists that have grown steadily on residential and commercial rooftop work.

Industry Overview: Solar PV Installation in Spain

Spain’s PV installer market spans an unusually wide range of scale, from integrated national utilities managing hundreds of thousands of self-consumption connections down to single-region specialists serving a handful of provinces. The companies in this curated selection illustrate that full spectrum, and reflect how the Spanish market has matured from a boom-and-bust regulatory history into one of Europe’s most active solar economies.

National Utilities and Integrated Groups

Iberdrola Clientes operates as the commercial arm of Iberdrola’s self-consumption offering and stands as one of the largest enablers of distributed solar at a national level, connecting well over 100,000 new installations in a single recent year. Acciona, headquartered in Madrid, has been active in photovoltaic energy since building what was then Spain’s largest solar plant in Tudela in 2001, and today spans the complete solar value chain from design and construction through operation and maintenance across a multi-gigawatt global portfolio.

Large EPC and Regional Installers

FOTOVOL SOLAR, based in the Girona region, has grown from a rooftop self-consumption specialist into a company handling ground-mounted commercial and industrial projects across Catalonia. Anbelo Solar, active in Castilla-La Mancha since 2005, and Bee Green Energy, based in the Canary Islands, both built their footprint through sustained regional project delivery for agricultural, residential, and commercial clients.

Established Local Specialists

Cambio Energético, Edeltime, Solarman, Insolac Renovables, and EAVE round out the list as established players within their respective regions, spanning Madrid, Catalonia, and Andalusia. Several of these installers began with residential self-consumption work and have since expanded into larger commercial and ground-mounted projects as demand for corporate solar has grown across the country.

Market Outlook

With Spain’s solar capacity projected to grow substantially through 2035, competition is intensifying at both ends of the market. Large utilities and EPC groups continue to scale up through self-consumption programmes and utility-scale project pipelines, while regional installers compete on local relationships, agricultural expertise, and turnkey delivery for small and mid-sized commercial clients.
