Green Solar International B.v.

What Green Solar International B.v. does

Green Solar International B.v. (GSI) is a family-owned solar development and investment company founded in 2019 in Maastricht, the Netherlands, by the Pelsers family. It specializes in large-scale photovoltaic project development and green hydrogen production across the Mediterranean, with operational offices in Maastricht, Alicante (Spain), and Limassol (Cyprus). The company's four core solution lines are ground-mounted solar installations on agricultural, industrial, and repurposed sites; rooftop installations including an asbestos roof replacement program; specialized installations such as floating solar, carports, and greenhouse-integrated PV; and green hydrogen produced via electrolysis powered by on-site renewable generation.

GSI executes an end-to-end project development model: identifying sites, securing land/roof options, obtaining permits, designing and engineering the system, negotiating power purchase agreements, contracting EPC capabilities, and advancing each project to Ready-to-Build (RTB) status. At RTB, GSI either co-invests in the operational asset alongside partners or sells the shovel-ready project to institutional investors, banks, and family offices. It manages over 1 GW of hydrogen projects and 400 MWp in active projects across Spain and Cyprus, with a strategic €500-900 million development pipeline in partnership with Israel's Doral Hydrogen and a 250 MW electrolysis alliance with SUEZ in Spain.

The founder's concurrent shareholding in Ampyr Solar Europe (1 GW operational, 7 GW under development across the Netherlands, UK, and Germany) provides a reference portfolio and a network for sourcing deals, capital, and engineering partners. GSI is privately held with no institutional equity funding disclosed to date and remains under Pelsers family control.

Revenue model

1. Project Development Services: GSI develops solar projects from early-stage identification through to Ready-to-Build (RTB) status, providing end-to-end development services including site identification, grid assessment, land securing, permitting, design/engineering, PPA negotiation, and financial modeling.
2. Co-Investment in Operational Projects: After achieving RTB status, GSI may retain partial asset ownership by co-investing in operational solar parks, generating ongoing returns from operating assets.
3. Project Sales to Investors: GSI sells completed/shovel-ready solar projects to investors (banks, investment funds, family offices), realizing development gains and freeing capital for new projects.

Functional benefit

Products and services

• Ground Structures Large-scale ground-mounted solar installations for agricultural land, industrial sites, dikes, ditches, and closed landfills, designed as dual-use developments that respect environment, landscape, and biodiversity while maximizing energy production.
• Roof Structures (Rooftop) Solar installations for rooftops of agricultural buildings, warehouses, and industrial facilities, including an asbestos roof replacement program that removes asbestos roofing and installs new roofs with solar panels and heat pumps at no initial cost to the owner.
• Specials (Solar Car Parks, Floating Solar, Greenhouse PV) Specialized solar installations for complex locations, including solar car parks providing shade and energy, floating solar plants on water surfaces using specialized floating techniques, and solar-integrated greenhouses with photovoltaic cells embedded in glazing.
• Green Hydrogen Green hydrogen production through electrolysis powered by on-site renewable energy, combining large-scale ground-mounted photovoltaic projects with electrolysers to produce green hydrogen and/or green ammonia for industrial applications, energy storage, and hydrogen-powered transportation.

• SUEZ Group: Global environmental services and water/waste management group. Strategic alliance partner with GSI for 250 MW of electrolysis capacity in Spain; broader group positioning as a renewable-gas offtake counterparty makes it comparable on integrated green-hydrogen value chains.

Regional players

• Audax Renovables: Iberian renewable energy company active in solar PV generation and supply across Spain and Portugal. Comparable as a regional player developing and operating Spanish solar assets with adjacent supply/retail energy offerings.

Direct peers

• Prosolia Energy: Iberian and European solar PV developer where GSI's Managing Director Spain previously led business development. Comparable business model focused on utility-scale project development, providing direct lineage and competitive overlap with GSI.
• Solaria Energía y Medio Ambiente: Madrid-listed Spanish solar PV developer with utility-scale projects across Iberia. Directly comparable as a Spanish-focused large-scale PV developer pursuing PPAs and corporate offtake, and a potential acquirer or competitor for GSI's pipeline.
• Doral Hydrogen: Israeli group with a 2 GW renewable portfolio across Poland, Romania, Denmark, Italy, and Bulgaria. Co-development partner with GSI for ground-mounted PV + green hydrogen/ammonia projects in Spain, making it the most directly comparable partner-developer combination.
