About BISOL Group

BISOL Group is active in the solar industry since 2004, when we started with the manufacturing of solar photovoltaic (PV) modules. We are considered to be a pure solar company that has in 2009 added PV mounting solutions and investments into solar power plants to our portfolio.

The many nicknames of BISOL Group

Being a solar specialist in all downstream segments, BISOL has been named the Solar Company. Due to our long‑term presence in a still rather young, but highly competitive industry, some prefer to call us “one of the solar dinosaurs” or “the glowing rocks” due to our stability and financial strength.
