Eighteen years on rooftops

Montserrat Vidal, an industrial engineer from Terrassa, and Rui Sampaio, an electrical engineer from Braga, met in 2006 on a PhD course on distributed generation that neither of them finished. Two years later they founded Luxsolaris in a ground-floor office in Poblenou with four colleagues.

Their first project was a 1.9 MWp plant in Alcarràs (Lleida), connected in September 2008. We still maintain it.

In 2019, with new self-consumption rules in Spain, we launched Luxsolaris Home. That year we installed 640 roofs. In 2025, 7,420.

To lead change in the way the world generates, stores and uses energy, integrating clean technologies, renewable energy and operational efficiency. Through responsible management of natural resources, we aim to maximise our positive impact on the planet and on the communities where we operate.

Innovation. Improving the craft every day. The clay-tile mounting bracket designed in 2023 by Manuel Cortés, then a crew leader in Seville, almost halved mounting time. All our crews use it now.

Sustainability. A system should deliver what we promised for 25 years, not just on the day it's connected.

Collaboration. Sales, engineering, installation and customer care work from the same customer file. You never have to repeat your story.

Social commitment. 1% of our profit funds Sol Compartido: free installations for food banks, care homes and day centres. And every year we hire people from job-integration programmes as installation assistants.
