What Solea does

Solea GmbH is a German photovoltaic EPC (Engineering, Procurement, and Construction) contractor headquartered in Plattling, Bavaria, offering full-lifecycle solar energy services from project development through construction to long-term operations and maintenance. Founded in 2007 and operating with approximately 30 employees, the company has installed over 350 MW of PV capacity across more than 14 countries spanning Europe, Africa, and Oceania, plus a separate track record of over 800 rooftop installations in Germany. Its core product lines include ground-mounted utility-scale solar parks and commercial, industrial, agricultural, and residential rooftop systems, supplemented by specialized offerings such as PV-diesel hybrid systems for off-grid applications, floating solar systems for water surfaces, and the proprietary Sunax New Generation single-axis tracking system engineered for uneven terrain.

The company generates revenue through three primary streams: one-time EPC project contracts sold to institutional end-investors (pension funds, infrastructure funds) via auction; ongoing operations and maintenance services delivered through its wholly-owned subsidiary Solea Service GmbH; and development fees for project rights including permits, grid connection agreements, and SPV structuring. Distribution operates through direct enterprise field sales targeting landowners, municipalities, and institutional investors for ground-mounted parks, alongside direct engagement with C&I customers for rooftop systems. The company maintains a financing ecosystem with first-class German lenders (DZ Bank, DKB, Bayerische Landesbank, GLS Bank) that co-finance projects and generate referrals.

In August 2023, Mainova AG acquired a 74.9% majority stake in Solea, integrating it into a major German utility's renewable energy strategy and providing balance sheet support, project financing access, and operational synergies. The company has stated plans to expand into MENA, North America, and India, and is extending its product surface to include BESS (Battery Energy Storage System)-coupled solar projects. Management includes CEO and founder Anton Schweiger, CFO Georg Sterner, and Managing Director Andreas Bach, who leads international project execution with responsibility for PV and BESS initiatives.
