About Us

Diagonal Bubble was founded in 2023 by two lifelong friends and entrepreneurs, Luis da Silva and Rui Lisboa Pedro. Their partnership is built on decades of trust, international experience, and a shared goal: bringing practical energy solutions to Portugal.

Rui Lisboa Pedro, Co-Founder, brings strong business and entrepreneurial experience from Canada. Luis da Silva, Co-Founder and CEO of Diagonal Bubble, is an experienced entrepreneur, logistics expert, and EV and high-voltage engineer, with technical expertise across automotive and industrial electrical systems.

Today, Diagonal Bubble is focused on renewable energy products and specialist services for homes, businesses, and property owners. Our offer includes solar fencing systems, battery storage, Aviloo battery diagnostics for electric and hybrid vehicles, infrared heating, and solar-based products such as solar glass, carports, and balcony power stations.

Our mission is to support energy independence in Portugal with reliable products, strong supplier relationships, and honest technical guidance. We are not building a price-driven webshop first — we are building trust, understanding demand, and helping customers find the right solution before scaling further.

At Diagonal Bubble, we believe modern energy should be practical, efficient, and built around real needs. We are here to create solutions that combine performance, resilience, and long-term value for customers in Portugal and beyond
