What exactly does tenant electricity mean?

Tenant electricity is the electricity supply for tenants through a solar system on the roof of the relevant apartment building. The solar power generated on the roof is delivered directly to the tenants in the house and consumed directly in the house. The unused electricity is then fed into the public grid and remunerated accordingly.

For the first time, tenant electricity offers tenants the opportunity to benefit from the energy transition. You can get clean electricity from the roof and save guaranteed: The electricity price offered is guaranteed by law to be at least 10% below the price of the local basic supplier.

However, not only homeowners can benefit from tenant electricity from a solar tenant electricity system. Commercial buildings such as factories are also ideal for producing their own solar power.

What if the sun doesn't shine?

No problem: the PV system still produces electricity even without sunshine. However, the yield is reduced somewhat. If the electricity demand is not sufficient, we simply supply green electricity from the public grid. As usual, the tenants are supplied with climate-friendly electricity around the clock.

What happens if the solar system produces too much electricity?

Of course, the electricity is not always used when the sun is shining most intensely. One possibility is to use local storage. This is used as standard in KfW40 + efficiency houses. Without such a storage system, the excess energy cannot be used in the house itself. It is not lost, however, but is fed into the power grid and can thus be used for other purposes. The electricity gets to where it is needed.

How is the PV system on the roof financed?

We offer various models for implementing the system. We fundamentally differentiate between self-financing and contracting through SOLARIMO.

All details about the models for cooperatives can be found here, commercial customers can find more here. If you are a contracting authority, this will help you out.

How long is the term of the contract?

A contract runs for an average of 20 years, as the EEG remuneration is guaranteed for this period. As a rule, however, PV systems generate clean electricity for more than 25 years. How to proceed with the system afterwards is to be decided individually and is stipulated in the contract. One possibility: SOLARIMO will completely dismantle the system on request and restore the roof to its original condition.

How is the electricity price made up?

SOLARIMO offers tenant electricity customers a simple tariff with just one price. This is a mixed calculation from the expected proportion of solar power from the roof, residual power from the grid, electricity generation costs as well as allocations and taxes. The tenants therefore always know exactly what price you are paying for the kilowatt-hour of electricity. Regardless of whether the sun is shining or not.

How does the electricity price brake work?

The photovoltaic system on your roof produces electricity at a fixed price over its lifetime. The price for the solar power share remains constant for the term of the yield. With a tenant electricity project, you and your tenants learn about price developments on the German electricity market.

How much money can tenants save with tenant electricity?

The electricity price offered is at least 10% below the price of the local basic supplier. However, our electricity tariffs are usually even cheaper.

Do the tenants have to get the solar power from the roof?

No. Of course, the tenants still have the free choice between the various electricity providers. The photovoltaic system on the roof of the house does not change that. However, our offer is very attractive for tenants, as solar power is not only green, but also cheaper.

How and how much CO2 can a PV system save?

When generating electricity using photovoltaic systems, unlike conventional electricity generation, no CO2 is released. For a holistic statement, however, the complete life cycle, including production and disposal (recycling), must be considered. The CO2 emissions of a PV system operated in Germany are around 50 grams of CO2 per generated kilowatt hour. For comparison: a lignite power plant generates 1,075 grams of CO2 per kWh and with natural gas it is still 499 grams.

What are the requirements for the building?

In order for a tenant electricity project to be successfully designed with SOLARIMO, a few minimum requirements must be met.

Rental houses need:

  • At least 20 residential units in the existing building and 12 in the new building
  • a large roof with as few disruptive structures as possible
  • Ideally a flat or pitched roof

Businesses require an exposed roof or other open space and must be able to use the electricity produced by the solar system on site.

What information does SOLARIMO need from you for an offer?

For a free indicative offer we need from you:

  • the object address
  • the number of residential units
  • the number of house connections for electricity
