We have specialized in open-space photovoltaic systems. Over the last 20 years, we have been able to implement projects with over 300 MWp of output at almost 50 locations nationwide. However, the planning and construction of roof-mounted systems are not part of our services.

Yes! Areas on which a ground-mounted PV system can be built generate very high rental yields, which are usually significantly higher than the conventional returns and rental income from purely agricultural use. This is guaranteed for at least 20 years, without risk and with annual payouts.

Basically, any open area that is not built up, not a forest, and not a biotope. Well-suited areas include fields, grasslands, meadows, or repurposed land. In almost all federal states, there are special regulations for land in agriculturally disadvantaged areas

You can build an economical open-space photovoltaic system starting from around 10 hectares. However, this also depends on factors such as soil condition or the distance to the nearest grid connection point.

In any case! It is common for solar systems to span several properties belonging to different owners.

The entire process planning, obtaining approvals with public and governmental participation, and finally the construction is extensive, costly, and requires substantial expertise. We take care of the entire process for you on the way to establishing a solar park.

We offer you an above-average lease agreement, which is significantly higher than typical regional agricultural rents. It is also possible for us to purchase the land if preferred.

Since every project and every area is unique, an automated return or lease calculator cannot provide accurate guidance. We offer to create an individual proposal for your area. This proposal is, of course, free of charge and can usually be provided within two working days.

No, absolutely not. You are guaranteed to receive the agreed rent. Solar-konzept covers all other costs related to project development, the approval process, and construction. 

Before construction work begins, a security deposit is placed to ensure the costs of dismantling are covered at the end of the lease term.

There is also the option of leaving the photovoltaic system to the lessor for continued operation. 

Once the system is completed, a diverse array of native plants will grow in the spaces between the solar modules, providing food for insects, including both domesticated and wild bees.

The areas where the systems are installed are fenced but have gaps at the base, allowing access for birds, amphibians, and small animals.

It is also possible to keep sheep on the area, creating a unique ecological environment.

Various types of open spaces are suitable for the installation of solar systems.

Agricultural land: Arable land or grassland can be used for solar parks, especially if the soil is less suitable for agriculture. Careful planning is important to us here in order to avoid conflicts with food production.

EEG areas: Areas defined under the Renewable Energy Sources Act (EEG) are particularly suitable. These include corridors along motorways and railway lines, conversion areas, and "disadvantaged" land in some federal states.

Brownfield and conversion sites: Former industrial areas or military sites often offer large, unused areas that are ideal for solar parks. They are usually already developed and have a good infrastructure.

Post-mining landscapes: Renatured areas from former open-cast mining operations or spoil tips can be used for solar plants.

After the end of the term of use, we ensure that the leased area is professionally and completely restored. This involves dismantling the solar systems, including all structural components, cables, and foundations, and disposing of them properly. 

Our dismantling work is carried out in close coordination with you to ensure that the area is returned in a condition that allows for agricultural or other uses. During the lease term, the soil can fully recover, which often improves soil quality.

In most cases, the areas are restored in such a way that they can be easily returned to their original condition. These obligations are contractually stipulated, so you can be sure that the area will be returned to you in a usable condition after the lease expires.

At solar-konzept, we take on every phase of the project - from the initial planning to the ongoing operation of the system. Here is an overview of the key steps:

1. Site analysis: First, we assess whether your area is suitable for a solar system.
2. Approvals: As your reliable partner, we take care of all the necessary permits, clarify environmental requirements and work closely with the responsible authorities.
3. Technical planning: We use the latest technologies to maximize the efficiency of the system and custom-tailor solutions to the specific local conditions.
4. Financing: With our experience in project financing, we identify suitable financing and funding options and prepare well-founded profitability analyses.
5. Construction & implementation: Once approval is secured, construction begins—professionally, quickly, and efficiently. We work with experienced partners who adhere to our high standards.
6. Operation & monitoring: Even after commissioning, we ensure that the system produces a lot of sustainable solar power through regular maintenance and reliable monitoring.

The entire process is fully organized - from analyzing the location and handling all legal matters to technical implementation and long-term operational management. Everything is managed by our experienced team from a single source.

Landowners have a point of contact at all times and can rely on long-term lease payments without needing to be actively involved in the construction process or system operation.

With us, the process remains uncomplicated for you, and you benefit from secure lease income over the long term.
