Redefining the photovoltaic industry for tomorrow's energy freedom.

Our aim is to create a sustainable system for partners companies and customers: a repeatable success story, with a fully sustainable value chain.

It is no coincidence that we were founded in Catania, in the Etna valley, at the heart of the Mediterranean Sea, the crossroad of European history.

Europe believes in us: within two years we will grow by fifteen times.

Through 3SUN’s CORE-H technology and the Gigafactory project, the production capacity of the 3SUN Gigafactory plant in Catania will increase from 200 MW to over 3 GW per year.

As we grow, the local community will experiment direct and indirect benefits, including 900 new direct and 1000 new indirect jobs.

Our Gigafactory will allow Europe to reduce its energy dependence. We will focus on production and sustainability acting as a catalyst to reshore the photovoltaic supply chain in Europe.
