Solar power for blocks of flats
Generating your own solar power is already common in detached houses. Now, owners of blocks of flats and tenants can also benefit from this electricity: with SWK Tenant Power!
You can also benefit from solar power if the properties are used for commercial purposes.
The electricity is supplemented 100 per cent by electricity from renewable energy sources, as verified by the ongoing redemption of green electricity certificates via the Federal Environment Agency’s Green Electricity Origin Register.

What is tenant-generated electricity?
The building owner leases the roof space to SWK Stadtwerke Kaiserslautern.
SWK is planning and installing a photovoltaic system there at its own expense, which will generate electricity on the roof.
Solar power is supplied to all households in the building that wish to use it.
If the sun isn’t shining, the solar power is supplemented by green electricity from the grid – ensuring a reliable, all-round supply.
The solar power generated on the roof and the remaining supply of SWK green electricity from the grid are conveniently combined into a single tariff as an affordable tenant electricity scheme.

SWK leases the roof –
everyone benefits
We install a photovoltaic system and generate solar power for the residents. Tenant-generated electricity is already possible for buildings with ten or more residential units.
As the owner, you don’t have to invest, organise or install anything. We take care of it all for you. With the SWK all-in-one package, you not only receive professional advice but also a comprehensive range of additional services. We handle maintenance, servicing and billing. It couldn’t be simpler.

Reference
In 2018, SWK installed solar power systems on three blocks of flats on Friedenstraße. This means that tenants are supplied with electricity generated directly on site.
“Stadtwerke Kaiserslautern have supported us as a competent and trustworthy partner and have taken care of the installation and operation of the system. And should the sun not shine sufficiently, a reliable electricity supply is still guaranteed by SWK Versorgungs-AG.”
Thomas Bauer, Managing Director of Bau AG Kaiserslautern

FAQ – Answers to the most frequently asked questions
What happens when the sun isn’t shining, for example at night? What if you use more electricity than your solar panel system can supply? In that case, we’ll automatically supply the rest as SWK green electricity from our grid.
There are no costs involved. We take care of the entire financing, installation, maintenance and operation of the solar panel system. Thanks to the roof lease agreement, property owners even benefit from a payment for the electricity they generate.
The only requirement is that you make the roof space available to us under a roof lease agreement. We’ll take care of everything else.
Each tenant is free to decide whether they wish to accept the offer and enter into a contract with SWK. This is an opportunity for tenants to purchase locally generated green electricity and save money.
In addition to the matters mentioned above, the contract sets out provisions regarding liability, roof repairs, restoration of the site upon completion, and transferability (a model contract is available on request). The term of the lease agreement is 21 years from the start of construction.
