Lease Agreements & Types 3 min read · published September 07, 2025

Many tenants in Germany consider whether they may install a small balcony PV system in a shared flat. As a tenant, you should know which clauses in the rental contract govern your rights and duties, when you need the landlord's consent, and which practical mistakes commonly lead to conflicts. This article explains typical mistakes in balcony PV clauses in plain language, shows how to act legally securely, which official laws and forms are relevant, and which steps can help in case of a dispute. The advice is specifically aimed at shared flats planning to operate a balcony PV system together and lists concrete measures for documentation and communication with the landlord. Read on for a step-by-step guide and concrete templates you can use.

What the clause regulates

A "balcony PV clause" in the rental contract typically describes whether and under what conditions tenants may attach plug-in photovoltaic devices. Important points are permission, liability for damage, handling of generated electricity, and dismantling on moving out. Legal bases can be found in the German Civil Code, especially regarding the duties of landlord and tenant.[1]

Tenants have statutory rights to use the rental property, but special uses such as power systems often require clear agreements.

Common mistakes in shared flats

  • No written landlord consent before installation.
  • Unclear rules for distribution or billing of the fed-in electricity.
  • No agreement on liability and costs for damage to the balcony or electrical connection.
  • No arrangement about dismantling and removal upon moving out.
  • Insufficient documentation of installation, photos and test reports.
Detailed documentation increases your chances of success in disputes.

Preparation before installation

  1. Check the rental contract for existing clauses on structural changes or technical installations.
  2. Obtain written landlord consent and document the content precisely.
  3. Have the electrical installation inspected by a qualified professional and obtain test reports.
  4. Record in writing how electricity is measured and billed or shared.
  5. Agree on a dismantling plan including deadlines and responsibilities.
Keep all emails, consent forms and invoices safe.

If a dispute arises

In case of disagreements try to reach an amicable agreement first: present documentation, set deadlines and offer a mediation meeting. If legal action becomes necessary, tenancy disputes are generally handled at the local court (Amtsgericht); higher instances are the regional court (Landgericht) or the Federal Court of Justice for legal precedents.[2] Observe procedural deadlines and formal requirements under the Code of Civil Procedure.

Submit documentary evidence in time to support your position.

Concrete forms and templates

Useful official templates include consent letters to the landlord and damage reports. For terminations or court letters there are templates from the Federal Ministry of Justice and procedural requirements under the Code of Civil Procedure.[3]

Use simple consent templates and attach annexes such as photos.

FAQ
