What Gransolar Group does

The business model combines four revenue streams: project-based EPC service fees (GRS), hardware sales of trackers and components (PVH), recurring O&M subscriptions over plant lifetimes, and project development transfers (e.g., the Eranovum agreement). Self-consumption projects (ISE Energía) and Balance of Plant services (GGC) contribute additional project-based revenue. Pricing is quote-based and project-specific, with no public pricing tiers. The go-to-market is enterprise field sales directed at utility-scale developers, IPPs, utilities, and large industrial energy consumers, supplemented by local offices and an agent network in non-office markets. The group disclosed 2022 revenue of €991M (84% YoY growth), EBITDA of €81M, and net profit of €44M, with a forward project portfolio of approximately €2.2B scheduled for 2023-2024. Trilantic became an equity partner in 2021.

Revenue model

1. EPC (Engineering, Procurement, Construction) Services: GRS provides EPC services for photovoltaic solar plant construction and grid connection. Revenue is earned on a project-by-project basis as a one-time service fee tied to the construction of utility-scale solar plants. GRS has built 127 plants worldwide with more than 4.5 GW of capacity.
2. Solar Tracker and Component Supply: PVH manufactures and supplies solar trackers, single-axis sub-structures, controllers, and SCADA systems to project developers and EPC contractors globally. PVH has supplied more than 50 GW of trackers worldwide across 45 countries. Revenue is generated through product sales.
3. Project Development: Gransolar Group develops PV and BESS projects from site identification and feasibility through to ready-to-build stage, selling projects or transferring them to developers/operators. The development pipeline includes projects in multiple markets worldwide.
4. Operation and Maintenance (O&M): ISE provides O&M services for the lifetime of photovoltaic plants. GRS O&M operates a Remote Control Center for 24/7 monitoring. Revenue is recurring over the plant's operational life.
5. Self-Consumption EPC (ISE Energía): ISE Energía delivers turn-key self-consumption projects for large industrial energy consumers. More than 150 MW in customized projects adapted to each company's needs. Revenue generated on a project basis.
6. Power Lines and Substations (Green Grid Connect): GGC specializes in high voltage electrical substations and BESS integration, constructing power lines and substations for PV and BESS projects. Revenue is project-based.
