Efficiency of self-consumption consortiums
Establish a self-consumption consortium
Self-consumption consortiums (ZEV – Zusammenschluss zum Eigenverbrauch) enable owners of functional and residential buildings to make their self-produced solar power available to their neighbours – even extending beyond neighbouring properties – for self-consumption, in return for a fee. Everyone benefits from self-consumption consortiums: you increase the profitability and efficiency of your solar panels whilst also making your neighbours or tenants happy by cutting the cost of their electricity. From apartment buildings to entire multi-building sites, we are here for you no matter what your ZEV needs are.
A self-consumption community (EVG – Eigenverbrauchsgemeinschaft) is a contractual agreement between several parties who jointly consume solar electricity which they produce themselves. The EVG is made up of property owners/operators of solar panels and several consumers. Consumers within the EVG may also be owners of a flat within a building or tenants.
Since the new Energy Act came into effect in 2018, what were once known as EVGs have been defined as self-consumption consortiums (ZEV –Zusammenschluss zum Eigenverbrauch), which has made solar projects even more attractive. Now it is possible to collectivise the solar electricity generated between neighbouring buildings, as well as among flats within the same building.
Financial benefits of a ZEV
Apart from the many environmental reasons for joining a self-consumption consortium, are there also financial benefits?
The answer is a resounding yes. As an electricity consumer, you benefit from the cheaper electricity and lower incidental costs associated with a ZEV, which can significantly reduce your electricity costs.
But a self-consumption consortium brings a whole host of benefits for landlords too. A solar installation increases the value of their property and sets it in good stead for helping to secure the environmental future of our planet. The property also becomes more attractive to potential tenants, as the ZEV allows them to benefit from lower electricity costs.
The investment in the photovoltaic system for the ZEV pays for itself after about twelve years. The more parties there are in a ZEV, the higher the electricity consumption – and the faster the solar installation pays for itself.

From apartment buildings to entire sites with several buildings, we are here for you and provide you with the tools to manage your energy in the most ideal way with a ZEV.
Electricity savings for tenants
In 2022, household electricity customers in Switzerland are paying an average of 21.2 centimes per kilowatt hour of electricity. The costs are thus 0.7 centimes higher than in the previous year. Tenants in a ZEV pay just CHF 0.12 per kWh for their own solar power, including operating costs.
A maximum of 80 % of the electricity consumption can be covered with a ZEV and a solar installation for private households. The rest of the electricity must be purchased on the market. The ZEV does, however, offer a financial benefit that should not be underestimated:
if the ZEV consumes more than 100,000 kilowatt hours per year, it does not have to buy the additional electricity from the grid operator but can instead negotiate the electricity price on the free market. This means that the purchased residual electricity can be obtained at a more favourable price.
In conclusion, a ZEV allows you to benefit from both affordable solar power and cheaper residual electricity.
Example calculation: electricity costs for tenants
| Electricity costs without ZEV | Electricity costs with ZEV | |
|---|---|---|
| Electricity supplied from local grid | 6,000 kWh per year | 4,000 kWh per year |
| Strompreis lokales Netz | 22,5 Rp. pro kWh | 17 Rp. pro kWh |
| Strombezug Solaranlage | 2000 kWh pro Jahr | |
| Strompreis Solaranlage | 12 Rp. pro kWh | |
| Nebenkosten pro Jahr | CHF 96.– | CHF 76.– |
| Total Stromkosten pro Jahr | CHF 1446.– | CHF 976.– |
In this example, a solar power share of around 33 % was calculated. The higher the share of solar power, the cheaper the electricity bill, because solar power is always cheaper than electricity from the grid.

Customised Solutions
The requirements for the size and power of the solar installation vary depending on the ZEV. The shape of the roof and the electricity consumption also play a key role in choosing the right solar panel system.
In order to create a perfectly adapted solar installation, we analyse your needs, the existing infrastructure and the electricity consumption as follows:
1. Evaluation and design
- We use portfolio analyses to evaluate on your behalf which properties are best suited to the self-consumption of solar power.
- We use economic efficiency calculations to illustrate the return for investors and the savings for tenants as a result of lower electricity costs.
- We examine the regulatory framework for the ZEV
- and use an implementation concept to guide you step by step through the process of setting up your own ZEV.
2. Establishing and setting up the ZEV
- Our partners establish the self-consumption consortium on your behalf
- and we take care of setting up all the necessary installations such as solar panels, meters, energy storage systems, a.s.o. We offer all services from a single source.
- If your electricity consumption exceeds 100,000 kWh, we procure the electricity on the free market on your behalf at a favourable price.
3. Operation and billing
- We measure your individual energy consumption using smart electricity meters.
- You can use our partner’s billing platform to effortlessly receive bill inserts with which you can settle the electricity costs.
