GIGA.GREEN, a commercial solar energy solutions provider, has closed a €30 million (~$35 million) revolving capital expenditure facility.
The funding was provided by Kommunalkredit Austria, a European specialist bank based in Vienna, which focuses on financing infrastructure projects in the energy, environmental, social, transport, and communications sectors.
“The financing solution is highly tailored to our needs and supports us in implementing our projects efficiently and sustainably,” said David Wagener, Head of Finance at GIGA.GREEN GmbH.
GIGA.GREEN offers commercial customers rooftop solar solutions without requiring upfront investments. By upgrading commercial rooftops with photovoltaic systems at its own expense and without requiring investment from customers, enabling them to purchase solar energy and monetize their available roof space.
According to the company, this funding will be used to strategically expand its nationwide project portfolio, focusing on industrial rooftop solar systems in Germany.
“This financing is another milestone in our mission to make CO₂-free energy accessible to companies, without any investment of our own,” explains. The revolving structure of the credit line allows us to deploy capital flexibly and efficiently across our project pipeline. This strengthens our scalability and underlines the institutional quality of our business model,” explains Wolfgang Röbig, Co-Founder and Managing Director of GIGA.GREEN.
Last year, in July, the company also secured €25 million (~$27 million) in equity from Ichigo, a Japanese sustainable infrastructure firm. Through this, Ichigo acquired a 24.39% stake in GIGA.GREEN, marking its first investment within Europe.
According to Mercom’s 1H 2025 Solar Funding and M&A report, solar debt financing activity in 1H 2025 reached $7.8 billion across 41 deals, representing a 41% decrease compared to 1H 2024, when $13.2 billion was raised in 51 deals.
In March, Apricus Generation, a distributed solar and battery development platform and independent power producer, announced that it has secured a $30 million revolving credit facility with Atlantic Union Bank. The funding is expected to provide the company with capital flexibility to accelerate project development.
