Tenants in Germany: Negotiate PV and Tenant Power

Modernization & Cost Allocation 3 min read · published September 07, 2025

As a tenant in Germany you often face technical and legal questions when the landlord plans a photovoltaic (PV) system or a tenant-energy model. This text explains in plain language which common mistakes tenants should avoid, which rights arise from tenancy law and how to conduct negotiations on modernization and cost allocation sensibly. We explain concrete checkpoints before consenting, which documents are useful and how to secure deadlines and wording. If you live in social housing, special rules on tenant-protection funding and the Wohnberechtigungsschein may apply; therefore review agreements particularly carefully and seek official or legal advice if uncertain.

What tenants should know

PV systems and tenant-energy can save costs long-term but raise immediate questions: who bears modernization costs, how does cost allocation affect utilities, and does habitability remain ensured? Many points are regulated by the Bürgerliches Gesetzbuch (BGB), for example duties to maintain the rented property[1], and the Zivilprozessordnung (ZPO) governs court procedures for disputes[2]. Before consenting, request clear details on costs, feed-in remuneration, contract durations and termination periods as well as a written agreement.

Keep all emails and invoices related to modernizations.

Common mistakes and how to avoid them

  • Accepting cost allocation without invoice review (payment): check exact amounts, distribution and periods.
  • Signing without a written agreement (form): demand a clear contract with duration, termination rights and maintenance rules.
  • Insufficient documentation (evidence): keep emails, photos and bills for later evidence.
  • Not clarifying maintenance and repair responsibilities (repair): clarify who is liable for roof, system or electrical damages.
  • Overlooked clauses on feed-in remuneration or price adjustments (warning): check whether price changes may impact you.
Documentation and written agreements significantly reduce later disputes.

How tenants should negotiate

Start with informational questions: who finances the system, what is the expected saving for tenants, are there subsidies and how long is a potential tenant-energy contract? Request technical documents and a profitability calculation. If costs are to be allocated, ask for detailed accounting schemes and compare additional costs with potential savings. For social housing, additionally check whether public funding rules (e.g. WBS regulations) are affected and whether they impose restrictions for tenants.

  • Contact property management early (call): clarify dates and documents.
  • Request written agreements (form): avoid oral arrangements without documentation.
  • Document defects and communication (evidence): photos and logs help later.

Rights, deadlines and court steps

Tenants can rely on statutory protections: duties to maintain and to report defects are regulated in the BGB[1]. Respond to formal modernization notices while preserving deadlines; otherwise consent might be considered implied. In serious disputes the Amtsgericht is competent for tenancy cases; appeal paths and litigation rules follow the ZPO[2]. If eviction is threatened, the procedure is highly formalized and typically requires court proceedings.

Respond promptly to legal letters and deadlines to preserve your rights.

FAQ

Can the landlord pass PV system costs on to tenants?
Only under certain conditions: modernization costs can sometimes be allocated to tenants if legal requirements are met and the allocation is transparent and comprehensible.[1]
What is tenant-energy and do I need to consent?
Tenant-energy means electricity from an on-site producer supplied to residents; changes affecting the tenancy, usage or costs should be agreed in writing and require your consent.
Which authorities or courts help with disputes?
The local Amtsgericht handles tenancy disputes; for legal precedent the BGH provides case law guidance.[3]

How-To

  1. Request documents in time (calendar): ask in writing for technical and economic documentation.
  2. Collect evidence (evidence): save emails, photos and bills systematically.
  3. Negotiate a written agreement (form): set terms for duration, prices, termination and liability.
  4. Seek official advice (call): contact local tenant or housing authorities about social-housing specifics.
  5. Check legal protection and prepare court steps if needed (court): document deadlines for legal action.

Key Takeaways

  • Always insist on clear written agreements before consenting.
  • Good documentation is your best protection in disputes.
