What Sunnerg Group Srl does

Sunerg Group S.r.l. is a Milan-headquartered General Contractor and Service Provider for B2B renewable energy projects, founded in 2017 by senior figures from the European solar sector. The company designs, builds, finances, and maintains utility-scale and rooftop solar photovoltaic installations, offering an integrated three-stage service stack: Development (site analysis, feasibility studies, permitting, PPA planning support), Construction under an EPC model (engineering, procurement, construction, commissioning), and 24/7 Operation & Maintenance. Its solutions are tailored to client needs, timing, and budget, and the company positions itself as a single interlocutor across the full asset lifecycle rather than a single-phase contractor.

The business operates through wholly-owned subsidiaries in the United Kingdom (Sunnerg Limited, Croydon) and Romania (Sunnerg Renewable Service S.r.l. and Sunnerg Construction S.r.l.), with project execution extending to Ukraine, Spain, and Portugal alongside the core Italy/UK/Romania footprint. It is ISO 9001 certified and GDPR-compliant, and reports a delivered track record of approximately 600 MW across more than 50 projects in five countries (with one company statement citing ~1,050 MW of total track-record capacity) and 50 active projects in its current portfolio. The go-to-market is direct enterprise sales targeting investment funds, national and international energy groups, and corporate energy buyers pursuing sustainability-driven procurement.

The revenue model combines one-time EPC contracting fees with professional services for development work and managed-services revenue from long-tail O&M contracts; pricing is custom and not publicly disclosed. The company is privately held and founder-led, with no disclosed institutional investors, venture capital, or private equity backing. Headcount is reported in the 30–60 range across sources, supporting execution across multiple concurrent European projects.
