Planning & construction
The planning of photovoltaic systems (PV systems) is a complex process that requires both technical expertise and careful preparation. The substructure, the creation of customised drawings and detailed parts lists are particularly important. These elements are crucial for the efficient and safe installation of PV systems and the long-term performance and reliability of the system.
Planning of PV systems
The planning of ground-mounted and agricultural PV systems differs from roof mounting and must take specific requirements into account:
- Site analysis: The design of the system must take into account the specifics of the respective site in order to guarantee efficiency.
- Conflicts of use: In the case of agrivoltaic systems, the subsequent agricultural use must not conflict with the installed systems.
- Regulatory requirements: Compliance with DIN standards, the Eurocodes and other building regulations is crucial.
The substructure
The substructure for ground-mounted PV systems must be robust and durable in order to meet the specific challenges of ground-mounted systems:
- Stability and anchoring: The substructure must be stable and securely anchored in the ground. This can be achieved using post foundations, concrete foundations or screw foundations, depending on the ground conditions.
- Weather resistance: The structure must be able to withstand extreme weather conditions, including strong winds, snow and rain. Corrosion protection measures are therefore essential.
Root system
- Firm anchoring despite low penetration depth into the soil.
- Can be used up to a slope inclination of 40°.
- Can be completely reused - Ideal for open land and agricultural areas.
Ground-mounted system
- Photovoltaic systems on large fields or unused areas.
- High performance potential due to their dimensions compared to roof systems and other PV systems.
- Modular design enables customised adaptation to local conditions.
Carport system
- Flexible PV carport system with short assembly time.
- Available as a single, double or industrial version.
- Made from zinc-magnesium-coated quality steel.
Agri-PV system
- Dual land utilisation - combination of agriculture and energy production.
- Photovoltaic systems also offer protection against intense UV radiation.
- Sustainable and efficient land use.
Drawings
- Detailed construction plans: Each component of the substructure is drawn in detail, including the exact dimensions, materials, connections and anchoring in the ground.
- Consideration of the site conditions: The drawings must take into account the specific conditions of the installation site, such as the slope of the terrain, obstacles and the route of supply lines.
- Integration with agricultural use: In the case of agrivoltaic projects, the drawings must also take into account the parallel use of the land for agricultural purposes, such as the height of the modules above the ground for growing crops or the passageways for agricultural machinery.
Creation of bills of materials
The bill of materials (BOM) is a central document for the planning and realisation of PV systems. It ensures that all required materials and components are available:
- Complete listing of all components: Every component, from the main structures to the smallest fastening elements, must be listed in detail.
- Quantity determination: The exact number of components required is determined in order to avoid material bottlenecks during the construction phase.
- Material procurement: The parts list serves as a basis for the procurement of materials and facilitates co-operation with suppliers.
- Cost control: A detailed bill of materials allows material costs to be precisely calculated and monitored, which is crucial for project budget planning.
Customised
- Customised planning: Each system is planned according to the specific needs of the customer and the local conditions. This also includes taking agricultural requirements into account.
- Flexible construction: The substructure and the overall solution must be flexible enough to adapt to different types of terrain and utilisation concepts.
- Adaptation to future requirements: The planning should also take into account future expansions or changes to ensure the longevity and scalability of the system.
Planning
The planning of ground-mounted and agricultural photovoltaic systems requires comprehensive and careful preparation. The substructure, the creation of customised drawings and detailed parts lists are crucial to the success of a PV project. These elements ensure that the systems are safe, efficient and durable and meet the specific requirements of the project. Tailor-made planning and implementation can optimise the use of solar energy and make a sustainable contribution to energy supply and agricultural use.

Occupancy & pile-driving plans
This process includes the creation of occupancy and piling plans as well as the optimal utilisation of space and the consideration of individual requirements. It is important that the available space is utilised in an ideal way. Minimising investment costs while at the same time optimising output is our maxim for this service.
Static calculations
These calculations are essential to ensure the safety and durability of the systems. Our company always has the structural analyses for our projects prepared by external engineering companies whose static and civil engineers are registered as structural engineers. On request, we can also have our structural analyses checked and green stamped by accredited structural engineers. This fulfils the high demands placed on structural stability, whether required by the relevant building authority or simply as a private-law inspection.
Geological surveys
Geological surveys are an essential part of the planning phase. Among other things, they also include a chemical analysis of the soil composition and thus not only guarantee the stability of the selected foundation form, but also ensure a professional definition of the service life in terms of corrosion protection.
Extraction test
Determining the ground conditions and load-bearing capacity is an essential step in the planning and realisation of photovoltaic projects. Various methods and techniques are used to ensure that the subsoil fulfils the requirements and that the safety of the construction is guaranteed. The most important methods include pull-out tests, which help to determine the load-bearing capacity of the soil.
