About us
A family business with a very clear idea of good work
Independent, installer-led and based in Zaventem. We would rather lose a sale than sell you something you do not need.
Our story
DELEX grew out of more than twenty years of electrical and renewable-energy work across Europe. Along the way we have helped more than 5,000 customers produce, store and use their own energy.
In Belgium, DELEX is led by an installer with over ten years of experience on Belgian roofs and in Belgian electrical panels. That shows in the details: realistic designs, clean installations and quotes that you can actually compare.
We stay deliberately independent. We are not tied to one brand, so we can choose the panels, inverters, batteries and chargers that suit your home — and explain why.
