Once planning permission has been granted, construction of the plant can begin. The project developer or the party that obtained the planning permission usually takes care of the realisation.

How does the construction phase work?

Construction of the plant takes usually only a few weeks to months. However, the Preparation of the surfaceThe construction of the plant, e.g. the measurement of traffic routes or cable trenches as well as the implementation of (regional) regulations such as the planning of nature conservation compensation, also takes some time. Once the construction of the plant has been completed, it still has to be Power grid connected become.

Before the start of construction

• Paths, stations, cable trenches are surveyed
• Possible old structures on the site, such as barns or explosive ordnance (in the case of conversion sites), are removed
• The nature conservation equalisation is planned
• Fences and site access road are erected
• Installations for construction site safety and accommodation are provided
• Logistics areas are created and the first materials such as piles and cables are delivered, and construction machinery is also provided

During the construction phase

• The cable trenches are created and the cables are laid
• The substructure for the solar modules is erected
• Modules are delivered and attached to the substructure
• Inverters and transformers are delivered and installed
• The individual components of the solar park are connected to each other
• The connection line to the electricity grid (usually the medium-voltage grid) is installed
• The solar park is being prepared for commissioning; at the same time, only the measures necessary for the construction work are being dismantled

Solar park & fire protection

For ground-mounted PV systems, it is not possible according to the German Fire Brigade Association DFV not requiredfire protection requirements such as fire brigade bypasses, fire brigade plans or extinguishing water supplies. This is because the Module rows at a sufficient distance to each other, so that on the one hand the Fire spread made more difficult and on the other hand, walkways already exist between the rows. In the event of a fire, the risk for emergency services is comparable to forest or open spaces.

An exception to this are areas with a high risk of forest/field fires, in particular areas of forest fire risk class A or A1, or e.g. drinking water protection areas. Additional requirements may apply here under certain circumstances.

Step 4: Operation & management of the ground-mounted PV system

After dismantling the construction site, the Operating phase of the solar park. The areas between the rows of modules and, where applicable, the compensation areas are cultivated in accordance with the requirements of the licence.
