Holaluz and LONGi partner to offer the most exclusive residential solar experience in the Spanish market

• Cutting-edge technology that maximises efficiency and makes the most of every available centimetre of roof space.
• Future-ready installations: operation even during power outages and ready for intelligent storage.

Barcelona, 4 June 2025. Holaluz, the green energy technology company, and LONGi, the global leader in photovoltaic innovation, have sealed a strategic alliance to bring the most sophisticated residential solar solution on the market to the most discerning homes. The agreement was signed during the latest edition of Intersolar Europe, the leading international solar industry gathering, held in Munich on 7-9 May.

As part of this collaboration, Holaluz will integrate LONGi's Hi-MO S10 (EcoLife Pro) module into its residential installations. This is cutting-edge technology based on HBC (Heterojunction Back Contact) architecture that offers efficiency of up to 25%, well above the current residential sector standard, which sits between 19% and 22%.

"The S10 module with HBC technology is the result of years of research and technological leadership by LONGi. Its presentation at Intersolar, the industry's most prestigious showcase, marks a milestone in our European strategy," notes Hugo Fernández, Managing Director of LONGi Solar DG for Southern Europe.

Beyond performance, the Hi-MO S10 stands out for its design: it is available in a carefully crafted all black version, allowing aesthetic integration on any roof. A solution designed for those who demand that sustainability also has style.

Holaluz's solar energy system installation, which combines next-generation modules with intelligent batteries, guarantees stable and continuous energy supply, even during power cuts. Furthermore, they are designed to integrate fully into Holaluz's decentralised network, offering homes clean, local and secure energy.

"This alliance allows us to offer our customers the best that exists in the market today: a solution that combines innovation, design and energy security to lead the new energy model from their homes," explains Carlota Pi, Executive President and Co-founder of Holaluz. "Every roof we install with this technology becomes a strategic asset, prepared for a cleaner, more efficient and resilient electrical system."

With this alliance, Holaluz reinforces its commitment to leading The Rooftop Revolution, a movement that transforms residential rooftops into generators of clean, decentralised and local energy, enabling families to become protagonists of the energy transition.
