Your roof. Your yield. Your simple solution for tenant electricity.

With B.One Mieterstrom powered by Quartierkraft, private landlords can generate electricity on their own roof, earn income, increase the value of their property, and simultaneously contribute to the energy transition. All without any technical or legal effort.

Even small systems are profitable!

Tenant electricity isn't just worthwhile for large buildings; even small apartment buildings benefit. With just a few units, you can generate profitable revenue through direct consumption, basic charges, grid feed-in, tenant electricity surcharge, and residual electricity margin, while simultaneously offering your tenants added value.

For a building with five residential units, this can generate over €2.500 per year.
