Stake holding

We advise and accompany people and companies working in the field of renewable energy. Our common goal: to measurably increase our own success with visionary ideas - and to protect the climate in the process. This is a big task, but a feasible and necessary one.

After all, we only have this one planet - and in the future we will be dependent on generating clean energy from solar power.

Photovoltaics consulting

Strategies without respect for emotions are like sailing without taking care of the wind.

Hardly any other competitive environment is subject to such dynamic change as that of renewable energies - through deregulation, the energy crisis and the worldwide increase in demand. C2sun develops practical and tailor-made solutions for you in order to make your strategies more flexible and to adapt them to the changed framework conditions.

Transformational coaching

At the beginning of every successful transformation there is always a sustainable vision.

We are currently experiencing the largest agile change process in German companies since the end of the Second World War. It is a time of great opportunities, but also of entrepreneurial risks. The consequences of this permanent change continuously give rise to new challenges for all of us. Anyone who masters them confidently is one of the economic winners.


Professional and outstanding specialists with the right expertise in the right place are the key to your success.

Targeted human resource management requires a consistent and flexible approach. The requirements and framework conditions in our industry are constantly shifting. You should therefore recruit employees for your organization who are not only motivated to deliver top-tier performance - but are interested in sticking with your company in the long term.

Stake holding

We contribute our expertise – as committed branch insiders in advisory or supervisory boards. 

Advisory boards are strategic partners for organizations. As external advisors, they are important for the development of a company, as they support the management with solar industry expertise and a critical view of the overall situation. Experience and qualifications are therefore important attributes for committed and good advisory boards.
