French Investment Accelerates Hungarian Solar Expansion with 58 MW PV Portfolio

Hungary’s solar market has reached another strategic milestone as French private investment firm ETIC Partners commits €6.5 million in junior debt financing to support two large-scale solar power plants with a combined capacity of 58 MW. The projects, owned and developed by ID Energy Group, are already operational as of 2025 and represent one of the most advanced examples of utility-scale solar investment and power purchase agreements (PPAs) in Central Europe.

This transaction is more than a financial headline. It underlines Hungary’s fast transition toward renewable energy, strengthens confidence in long-term solar PV investments, and reinforces the country’s role as a key solar hub in the European energy transition.

For professional solar installers, EPC companies, solar wholesalers, and PV project developers, this deal sends a clear signal: Hungarian solar infrastructure is bankable, scalable, and strategically aligned with EU climate objectives.

€6.5 Million Junior Debt for 58 MW of Solar PV Capacity

ETIC Partners, through its Energy Transition Europe II fund, provided junior debt financing to ID Energy Group to support the construction and commissioning of two solar plants totaling 58 megawatts (MW).

These utility-scale solar plants:

• Became fully operational in 2025

• Generate approximately 80 GWh of electricity per year

• Avoid nearly 11,000 tons of CO₂-equivalent emissions annually

• Contribute directly to Hungary’s renewable energy targets

Junior debt plays a crucial role in renewable energy financing by improving capital structure flexibility while enabling developers to scale portfolios faster. For the Hungarian solar sector, this transaction confirms that international investors see long-term stability and growth potential in the market.

METÁR Incentives and One of Hungary’s Largest Solar PPAs

One of the two solar plants benefits from Hungary’s METÁR renewable support scheme, which provides predictable revenue through state-backed incentives. This ensures long-term financial stability and bankability — a key factor for investors and solar project owners alike.

The second plant operates under a 15-year Power Purchase Agreement (PPA) with Holcim’s Hungarian subsidiary, supplying renewable electricity at a fixed price. This PPA is among the first and largest successfully concluded solar PPAs in Hungary, marking a turning point for corporate renewable procurement in the region.

Why this matters for the solar market:

• Demonstrates maturity of Hungary’s PPA framework

• Reduces merchant risk for utility-scale solar plants

• Encourages industrial consumers to secure long-term renewable electricity

• Sets a benchmark for future solar PPAs in Central and Eastern Europe

For EPCs and solar developers, this signals increasing demand for bankable, utility-scale PV systems, high-performance solar panels, and grid-compliant solar inverterssuitable for long-term PPA-backed projects.

Hungary’s Solar Growth: From 6.8 GW to Nearly 12 GW by 2030

Hungary’s National Energy and Climate Plan (NECP) sets an ambitious goal:
30% renewable energy in gross final consumption by 2030.

Solar energy is the backbone of this strategy.

• Current installed solar capacity: ~6.8 GW

• Target by 2030: nearly 12 GW

• June 2025 milestone: over 40% of national electricity supplied by solar

This record-breaking performance highlights Hungary’s ability to integrate high shares of solar PV into the grid — a critical factor for future investments in energy storage, hybrid inverter systems, and grid-balancing technologies.

For the wider solar supply chain, including solar distributors and solar wholesalers, this expansion translates into sustained demand for:

• Utility-grade solar panels

• Central and string solar inverters

• Energy storage systems and solar batteries

• Monitoring, grid protection, and BOS components

ID Energy Group: A Proven European Solar Developer

The projects are owned by ID Energy Group, a Spanish renewable energy company with a strong international footprint. Since its founding in 2008, the group has built a reputation for developing high-quality PV and biogas assets across multiple markets.

ID Energy Group at a glance:

• Active in Spain, Poland, Italy, Hungary, Serbia, Croatia, and Chile

• 6.5 GW renewable project development pipeline

• 284 MW of projects sold

• 500+ MW currently in operation

• Specialisation in solar PV projects and biogas units

Their Hungarian portfolio demonstrates how experienced developers can successfully combine state incentives, corporate PPAs, and international financing to deliver large-scale solar infrastructure.

ETIC Partners and the Energy Transition Europe II Fund

ETIC Partners is a French private investment firm focused on financing projects that accelerate the energy transition across Europe. The launch of its second junior debt fund, Energy Transition Europe II, has significantly expanded its impact.

Key highlights:

• Fund launched one year ago

• 16 transactions completed since 2021

• Over 680 MW of renewable capacity financed across Europe

This Hungarian transaction strengthens ETIC’s role as a catalyst for renewable energy investments and confirms the attractiveness of solar PV as a stable, long-term infrastructure asset class.

What This Means for the European Solar Supply Chain

Large-scale investments like this have a direct ripple effect across the solar ecosystem:

• Solar wholesalers benefit from predictable demand for utility-scale components

• Solar distributors expand stock of grid-compliant inverters and PV modules

• EPCs and installers gain confidence to bid on larger, long-term projects

• Energy storage solutions become increasingly relevant as solar penetration rises

As Hungary moves toward 12 GW of installed solar capacity, the role of energy storage, hybrid solar inverter systems, and complete solar kits — even at utility scale — will become essential to maintain grid stability and maximize solar self-consumption.

Solar&Solar Perspective: A Strong Signal for Central Europe

From a Solar&Solar perspective, this investment confirms what the market has already shown:
Central Europe is no longer an emerging solar region — it is a core growth market.

Hungary’s ability to attract French capital, Spanish developers, and multinational industrial off-takers reflects a mature solar ecosystem built on:

• Bankable regulation

• Proven grid integration

• Competitive solar technology

• Reliable solar PV suppliers and wholesalers

For installers, EPCs, and project developers sourcing high-quality solar panels, solar inverters, energy storage systems, and complete solar solutions, the momentum is clear and accelerating.

Conclusion: A Blueprint for Future Solar Investments

The €6.5 million investment by ETIC Partners into 58 MW of Hungarian solar capacity is more than a single transaction. It is a blueprint for future renewable energy development in Europe — combining policy support, private capital, long-term PPAs, and proven solar technology.

As Hungary continues its rapid solar expansion, projects like these will define the next phase of Europe’s clean energy transition — and reinforce the importance of reliable solar PV suppliers, distributors, and technology partners across the value chain.
