    How Our Projects Go

    We offer you the ability to increase your profits sustainably and constantly using the right roof-mounted plant concept. We look after the complete project planning from concept creation through planning permission to installation and starting to provide electricity to the grid.

    1. Project design with cost listing

    The concept includes a non-binding offer incl. a list of costs, plant layout and economic assessment.

    2. On-site meeting to clear up the final technical matters

    3. Execution

    Once the approval phase is over and the EEG contract has been presented, we can start building the plant. We will commission and manage the entire construction.

    4. Fine adjustment incl. grid compatibility test

    In order for you to be able to profit from self-generated green electricity in the future, we need to carry out a grid compatibility test to be submitted to your local grid operator. For existing buildings, we also need to carry out a statics evaluation and certify your roof-mounted plant.

    5. Binding offer for our services

    6. Assembly & installation of the roof-mounted plant

    7. Approval & commissioning of the energy solution

    8. Operational management


    According to the EEGs, there has been a demand since 2014 for the annual construction of 2.5 gigawatts of solar production capacity in Germany.

    All large solar plants or other plant structures of over 750 kW need a tendering process – the volume of this sub-section is 600 MW. The tendering process is carried out by the Federal Network Agency three times per year.

    Feeding Into The Public Grid

    There are further options if your plant produces more electricity than is needed – you can feed it into the public grid.
