    Does tenant electricity pay off?
    The honest answer.

    Tenant electricity can be highly profitable, or a loss-making venture. The difference lies in the model, assumptions and regulatory coverage. Here's what matters.

    No sales talk. Just numbers.

    Why many feasibility calculations are misleading

    PV providers only calculate best-case - real consumption profiles, vacancy and degradation are missing.

    Model selection not compared - full supply, surplus and contracting have completely different return profiles.

    Tax effects (trade tax, VAT deduction) are ignored or incorrectly applied.

    No scenario comparison - what happens with 20% less yield or 15% vacancy?

    Does this sound like your situation?

    Let's clarify in a free initial consultation whether and how we can help.

    What makes a reliable feasibility calculation

    A serious tenant electricity calculation considers at minimum: self-consumption ratio, residual electricity supply, metering concept costs, PV degradation, vacancy rate, tax treatment and financing structure. Only when all parameters are correctly modelled does a reliable decision basis emerge.
    The tenant electricity surcharge under § 21 EEG 2023 is currently 2.37 ct/kWh for systems up to 10 kWp.
