HELIUP

HELIUP is a French greentech startup founded in 2022, specializing in lightweight solar photovoltaic (PV) modules tailored for large rooftops on buildings with low load-bearing capacity.

Headquartered in Le Bourget-du-Lac, Auvergne-Rhône-Alpes, the company operates a 4,000 m2 production facility in Le Cheylas, Isère, which began operations in January 2025. HELIUP's innovative technology, developed from advanced research at CEA-LITEN, features ultra-thin glass that reduces the weight of PV panels by over 60% while maintaining performance. The company's primary product is its ultra-light photovoltaic panel, weighing around 5 kg/m2. These panels utilize a unique direct bonding installation method, eliminating the need for heavy mounting structures. HELIUP offers comprehensive solar integration solutions, focusing on renewable energy generation, energy cost control, and building performance improvement. Their services cater to B2B clients, including commercial buildings, industrial facilities, logistics centers, public sector entities, and agricultural buildings. HELIUP aims to harness the potential of underused surfaces in France, contributing to energy efficiency and sustainability.
