The energy of the sun

And the services we provide to deliver highyield solar parks

The sun is one of the most important energy suppliers for the sustainable energy system of the future. Since GP JOULE was founded, project planning, implementing and operationally managing solar parks and other PV projects has therefore been part of our core business. We design solar park projects to be economically viable and successful in the long term - for everyone involved. Municipalities, landowners, investors and operators trust our holistic, full-service approach and the high level of expertise of our photovoltaic project development team.
