About us

Why choose solar energy?

Solar panels contribute to a cleaner living environment by not emitting harmful emissions. Moreover, with solar panels you are no longer dependent on the power grid and you can earn back the investment in solar panels within a few years time.  

“It is our vision to make solar energy available to everyone, everywhere.”

Who are we?

We are a group of sustainable companies representing the solar branch of Koolen Industries. It is our mission to make solar energy available everywhere and to everyone. By collaborating with other companies that store, transport and deliver clean energy, we can utilize our clean energy in all kinds of applications. Think about solar panels connected to different kinds of clean energy storage containers, varying from lithium batteries to ammonia and hydrogen bromine. Or connected to charging infrastructure for electric vehicles. Together we can make sure clean energy will be available to everyone.
