Solarpro Holding

What Solarpro Holding does

Solarpro Holding is a privately held, Bulgaria-rooted Engineering, Procurement and Construction (EPC) contractor for utility-scale renewable energy infrastructure, operating through a UK-domiciled holding entity (Solarpro Holding PLC, London) and a Bulgarian operating subsidiary (Solarpro Technology, Sofia). Over a 17-year operating history, the company has designed, built and integrated more than 14 GWp of photovoltaic (PV) capacity across 300+ plants, delivered over 4 GWh of battery energy storage system (BESS) capacity, and engineered 10 high-voltage substations for grid connection. Its core offering spans four technology pillars — solar PV, wind, BESS, and hybrid PV+Wind+BESS+Hydrogen solutions — supplemented by 24/7 Operations & Maintenance (O&M) services across 6 GW of assets and an industrial-scale recycling facility for end-of-life PV modules and lithium batteries. A proprietary SCADA & Energy Management Platform, delivered as a SaaS layer, provides monitoring, predictive analytics, anomaly alerting, and third-party integration via REST API and standard protocols (Modbus, IEC 61850, IEC 60870-5-104, DNP3).

Solarpro's revenue model is predominantly project-based EPC contracting for utility, transmission system operator (TSO), and large corporate offtakers, complemented by a recurring O&M and grid-integration services stream. Pricing is negotiated on a per-project basis and not publicly disclosed. Go-to-market is enterprise field sales through regional offices in Bulgaria, the UK, Romania, North Macedonia, Poland, India (engineering hub) and China (sales office), targeting utilities, IPPs, TSOs, and corporate energy buyers executing virtual power purchase agreements (VPPAs). Notable enterprise customers include Ardagh Glass Packaging-Europe (12-year VPPA, 110 GWh/yr), the Bulgarian Electricity Grid (602 MWh BESS integration), and joint-venture partners Rodopi Grid Services and Ventura Energy Partners CE on an 80 MW/320 MWh BESS project under Bulgaria's RESTORE programme. Capital partners include the International Finance Corporation (IFC) and Raiffeisen Bank International, which jointly provided EUR 90 million in construction financing for the 225 MW St. George Solar Park with 90 MW/240 MWh BESS.

Operationally, the group employs 1,500+ professionals and holds ISO 9001, 14001, 45001, and ISO/IEC 27001 certifications across both the Technology and Holding PLC entities. The company is founder/management-owned, with no disclosed institutional equity investment or public listing. Its competitive position rests on multi-technology integration capability, in-house construction capacity via Solarpro Construction, a vendor-agnostic proprietary SCADA platform, end-of-life recycling infrastructure, and a 17-year delivery track record across 16+ countries in Europe, MENA, and Asia.
