HELIUP, a solar photovoltaic module manufacturer for the large rooftops of commercial and industrial buildings, closed a €16 million (~$19 million) funding round.
Supernova Invest led the funding round, alongside new investors including MAIF Impact, Lita Gestion, C2AD, as well as existing partners Starquest Capital and BNP Paribas Développement. Avolta Partners supported HELIUP with the structuring and implementation of the transaction.
Headquartered in Le Bourget-du-Lac (Savoie, France), the company develops and manufactures lightweight photovoltaic panels specifically designed for large rooftops. In 2023, the company launched its 10 MWp pilot line as part of the France 2030 program.
The funding is expected to support the company in strengthening its commercial teams across Europe, the expansion of production capacity at its French industrial site, the preparation of additional replicable production units, and continued efforts to maintain a sustainable technological edge.
“This funding round gives us the means to accelerate HELIUP’s industrial deployment at a European scale. Our ambition is clear: to finally make millions of square meters of currently unused rooftops solar-ready and transform existing buildings into true energy infrastructure. By equipping existing rooftops, we enable building owners and operators to sustainably reduce their energy costs, enhance the value of their real estate assets, and comply with new regulatory requirements related to the energy transition,” said Yannick VESCHETTI, President of HELIUP.
In 2024, HELIUP completed a €10 million (~$11 million) funding round led by Starquest Capital, with participation from EIT InnoEnergy, BNP Paribas Développement, and Groupe IDEC. Later in 2025, the company reached industrial scale with a 100 MWp factory supported by the European Union’s Innovation Fund.
According to Mercom’s recently released Annual and Q4 2025 Solar Funding and M&A report, Global VC and private equity funding in the solar sector in 2025 totaled $3.5 billion across 75 deals, 22% lower than the $4.5 billion raised in 60 deals in 2024. There were eight VC funding deals of $100 million or more in 2025.
