Austria has positioned itself as a strong performer in the European solar transition, backed by an ambitious target of balancing renewable and consumed electricity by 2030 and a national rooftop solar incentive programme that has driven rapid residential and commercial adoption. Behind that growth sits an installer market shaped at the top by a national utility group and a major construction contractor, and further down by specialist developers and regional installers. This article presents a curated Top 10 of PV Installers in Austria, selected for overall scale and significance within the Austrian solar market.

Industry Overview: Solar PV Installation in Austria

Austria’s PV installer market is shaped at the top by two very different kinds of organisations operating at national scale: a leading energy utility with a fully integrated residential solar arm, and a pan-European construction group delivering utility-scale systems as part of a much broader infrastructure business. The companies in this curated selection span that full range, down to specialist developers and regional installers concentrated heavily around Vienna.

National Utility and Construction Scale

VERBUND, Austria’s leading energy company and one of the largest producers of electricity from renewable sources in Europe, has expanded its solar footprint through the acquisition and full integration of residential specialist SOLAVOLTA. STRABAG, one of Europe’s largest construction groups, delivers photovoltaic systems as part of its renewable energy division, ranging from corporate rooftop installations to large utility-scale ground-mounted parks built for utilities and municipal energy providers.

Developers and EPC Specialists

Amarenco Solar Austria, part of the internationally active Amarenco Group, and Enery Development, a pan-European developer with a strong footprint across Central and Eastern Europe, both bring cross-border development and EPC expertise to the Austrian market. SELINA PHOTOVOLTAIC and ÖKOVOLT Solartechnik round out this group with established regional operations spanning multiple Austrian provinces and, in ÖKOVOLT’s case, an international footprint extending into Germany and Switzerland.

Regional Utilities and Specialists

TIWAG-Next Energy Solutions operates as the energy solutions arm of Tyrol’s regional utility TIWAG, while CCE Holding, ImWind Erneuerbare Energie, and LSG Group represent Vienna-based developers and specialists active across the broader Austrian renewable energy sector.

Market Outlook

With Austria targeting a fully renewable electricity balance by 2030, continued growth in both residential and utility-scale solar is expected, supported by national incentive schemes and grid expansion. Competition between large utility-backed platforms, international developers, and regional specialists is likely to intensify as the market matures and consolidation activity picks up.
