About us
The idea was born at COESA srl, one of the leading energy‑efficiency companies in Piedmont.
By studying the market, technological progress and the timing of the “end‑of‑life” issue for solar panels, we asked ourselves a simple question: why are we wasting such an important resource?
We decided it was time to do something concrete.
Where we started
We already knew the solar sector before KeepTheSun. COESA is a key player in industrial photovoltaics and accessibility to the energy transition is our mantra.
From there, we set out to build a platform fully dedicated to used solar panels and to proper end‑of‑life handling.
We face new challenges with determination, backed by COESA’s proven experience.
