3Lease Agreement and Photovoltaics: Important Basics and Legal Notices
Photovoltaic systems are an efficient method of converting solar energy into electricity, help reduce CO₂ emissions and offer financial incentives thanks to the Renewable Energy Sources Act (EEG). But what legal aspects must be taken into account when integrating photovoltaic systems into lease agreements? Here is an overview of the most important legal principles:
leasehold: The German Civil Code (BGB) in sections 581 – 584a regulates the essential provisions for leasing land and buildings. These paragraphs define the rights and obligations of the contracting parties as well as the conditions for the lease term.
Building law and EEG: For the construction and operation of photovoltaic systems, not only building regulations are decisive, but also specific requirements of the grid connection and the EEG must be observed.
Specific regulations: These include regulations concerning the responsibilities of the parties involved, necessary permits and participation in the profits of the investment.
These legal frameworks are essential for drawing up legally secure lease agreements in the field of photovoltaics.

Photovoltaic systems on leased land: Legally secure regulations in the lease agreement
The installation of photovoltaic systems on leased land requires clear contractual regulations regarding responsibility, operation and maintenance. The following points should be specified in the lease agreement:
Tenant’s authority and responsibility:
The tenant receives the right to install photovoltaic systems as long as he meets legal and contractual requirements and obtains the necessary permits.
Grid connection and electricity sales:
The lessee is entitled to feed the electricity into the public grid and can sell the generated electricity to third parties, such as the grid operator.
Lessor's consents:
The lessor grants the necessary rights of use, including the use of roof areas or parts of the property and, if necessary, the registration of security mortgages.
Cost regulation:
The construction, operating and maintenance costs are borne by the lessee, unless otherwise agreed;
these can be offset against the rent.
These regulations ensure a reliable basis for the operation of photovoltaic systems on leased land.
Photovoltaic lease agreement: Important agreements for tenants and lessors
A clearly structured lease agreement for photovoltaic systems defines the rights and obligations of both parties and thus creates the basis for successful cooperation. Here are the essential regulations for photovoltaic lease agreements:
When using photovoltaic systems on leased land, the clear division of responsibilities between tenant and lessor is crucial for smooth and efficient use.
Tenant’s responsibilities: The lessee is usually responsible for the entire planning and construction of the plant as well as the ongoing operation, including maintenance and necessary repairs. It is also his responsibility to submit applications for funding, obtain the necessary permits and ensure the grid connection.
Obligations of the lessor: The lessor provides a structurally suitable area for the installation of the photovoltaic system and ensures the necessary access and pipeline rights to enable the operation of the system.
Liability: It clearly regulates who is liable for damage caused by faulty planning, construction or operation in order to avoid ambiguity and potential conflicts.
Financial aspects: The costs for construction, operation and maintenance of the plant are shared between the lessee and the lessor. In addition, an agreement is made on the profit sharing, whereby the lessor can receive either a fixed amount or a percentage of the feed-in tariff. The regulations for invoicing income and costs and for the distribution of the ongoing feed-in tariffs are also an essential part of the contract.
Contract duration and termination: The term of the lease is chosen so that it corresponds to or exceeds the lifespan of the photovoltaic system. At the end of the lease, it must be clarified whether the system will be taken over by the lessor or dismantled and disposed of by the lessee. The conditions for early termination of the contract, whether through termination or insolvency, are also precisely defined.
These comprehensive regulations ensure that the operation of photovoltaic systems on leased land is both legally secure and economically advantageous.
Legally secure legality check for lease agreement and photovoltaic system
In order to minimize legal risks and ensure the economic use of the photovoltaic system, a comprehensive legality check is essential before the contract is signed and the system is built. This check covers several important areas:
Building law review: It must be ensured that the construction and operation of the facility is permitted under building regulations. It is particularly important to comply with building clearances and to take into account specific usage requirements for the site.
Grid connection and feed-in tariff: A thorough review of the grid connection obligations and the feed-in tariff regulations is necessary to ensure conformity with the grid operator's requirements.
Contractual conformity of use: It must be checked whether the use of the photovoltaic system is compatible with the leased property, such as agricultural land.
Coordination with relevant authorities and approval procedures: All necessary permits, including those for construction, monument protection and nature conservation, must be obtained. Close coordination with the responsible authorities is necessary.
A thorough legality check lays the foundation for legally secure and economically advantageous use of photovoltaic systems on leased land. This careful preparation helps to avoid later conflicts and maximize the profitability of the investment.
