About Us

We are Sun4G, a business unit of Gieffe-Impianti, a young, dynamic, and innovation-oriented company specializing in the installation of photovoltaic systems and energy efficiency solutions. We believe the sun is the most valuable resource to build a more sustainable world, and we work every day to transform it into clean, accessible, and cost-effective energy for everyone.

Our philosophy is simple: combine smart technology with a green mindset to guide families and businesses toward energy independence. Every project is managed with passion, expertise, and attention to detail, from the initial consultation to post-installation support.

With Sun4G, you don’t just choose a system—you gain a reliable partner who shares your values: innovation, sustainability, and a forward-looking approach.
