Trilantic Europe’s €425M Bet: Gransolar’s Vertically Integrated Solar Ambitions

The acquisition of a majority stake (60 %) in Gransolar by Trilantic Europe for about €425 million represents a major PE investment in the Spanish renewable energy sector. It reflects both confidence in the near-term profitability of solar photovoltaic (PV) technologies and the importance of scale, integration, and global expansion in the sector.

Gransolar is differentiated by its vertical integration—from designing and manufacturing trackers (a critical cost component in utility-scale solar) to developing ready-to-build projects, construction, and energy storage solutions. This positions it well in markets where accelerating deployment depends not just on project development but also on control over supply chains and technical innovation. [1][3]

Trilantic Europe’s investment aligns with its mid-market, pan-European strategy targeting companies that can leverage operational synergies, international expansion, and rising ESG/energy transition tailwinds. By partnering with the founding shareholders, who retain 40 % and remain in leadership roles, the deal mitigates execution risk associated with management transitions. [3][1]

The advisory structure—Uría Menéndez leading on the buy-side counsel, with Latham & Watkins supporting cross-border and competition, and EY Abogados providing tax, regulatory, urban planning, data protection, labour, IP, and legal advice—suggests a complex deal that navigates multijurisdictional regulatory regimes and high compliance demands likely to arise given Gransolar’s presence across Europe, the Middle East, and the Americas.

Strategic implications include: Gransolar gaining financial firepower to increase its R&D, scale manufacturing, and expand into new geographies—potentially entering markets with higher regulatory risk or less developed supply chains. For Trilantic, this is a bet on large-scale renewables where barriers include permitting, ESG compliance, supply chain risk, and inflation in component costs.

Open questions remain: What is the timeline and scope of the regulatory approvals required, especially in the US or under export-control regimes (e.g., CFIUS)? What leverage does Trilantic obtain over capital allocation, R&D spend, and management strategy? How will the integration of storage and tracker manufacturing scale relative to competitive pressures from low-cost producers in Asia? Finally, what contracts or pipeline projects does Gransolar already hold, and how large is the addressable market it targets post-deal?
