Solar panel system subsidies for large customers


Subsidies for solar panel systems from 600 m²


The Swiss federal government and the cantons pay subsidies to companies that operate solar panel systems and use renewable energies for their own consumption. The subsidy amount varies depending on the capacity (kWp) and size of the photovoltaic system.

There are various subsidy options for large photovoltaic systems. Owners of properties of 600 m2 or more have the choice between a large one-off payment (GREIV) or the recurring feed-in remuneration (KEV or EVS feed-in remuneration system).

Large one-off payment (GREIV)

The GREIV is a one-off payment that covers up to 30 % of the investment costs of the solar panel system and is paid out to the system owner by the Swiss Federal Office of Energy. The GREIV is for solar panel systems with an output of between 100 kWp and 50 MWp (from 600 m2).


In addition to the large one-off payment, there is a small one-off payment (KLEIV), which is intended for smaller photovoltaic systems of 10 m2 to 600 m2. With the KLEIV, solar panel system owners are reimbursed a maximum of 30 % of the investment costs. Once the photovoltaic system has been commissioned, it takes approximately two years for the small one-off payment to be made.


In contrast to the KLEIV, registration for the GREIV can take place before the solar panel system is commissioned.

We apply for the GREIV on your behalf:
Registration of the system by Helion Commissioning of the system by Helion Partial reimbursement of purchase costs
Before installation begins, Helion obtains all the necessary forms for registration. So you can sit back and relax. After the solar system has been registered with the state, our experts begin planning and installing your system. The pay-out is guaranteed by law and takes place about six years later. The date on which your application is received is key here.

As a rule, industrial customers have facilities with an area of more than 600 m2, which is why GREIV is the most important funding instrument for industrial customers.

Receiving the one-off payment

Due to high demand, there is currently a waiting period of about six years for the GREIV to be paid out.


If the operator of a system with more than 100 kWp (larger than 600 m2) opts not to register for the GREIV, they can switch to the KLEIV. By switching to KLEIV, the waiting period until payment is reduced to two years, but at the same time the subsidy amount is also reduced.


Cost-covering feed-in remuneration (KEV)

Until the end of 2017, operators of large photovoltaic systems received a contractually agreed remuneration rate from Swissgrid.


With the entry into force of the new Energy Act on 1 January 2018, the principles underlying this situation have changed. As of 1 January 2018, cost-covering feed-in remuneration (KEV) is no longer available for the commissioning of photovoltaic systems. Only applications with an application date before 30 June 2012 will be considered.

Direct sale: a new subsidy system

If you own a solar system with an output of more than 500 kWp, direct sale is mandatory. However, this situation rarely occurs.


With direct sale, photovoltaic system owners are responsible for selling their solar electricity themselves. Instead of receiving a cost-covering feed-in remuneration, as is the case with KEV, system owners can sell their electricity at market prices.

The right time for a solar panel system

Due to the high demand for photovoltaic systems, there has been a lot of activity in the solar energy market in recent years. Photovoltaic systems currently cost just 20 % of the price you would have paid ten years ago.


However, government subsidies now tend to be decreasing. That is why the best time to buy a solar system is right now: the longer you wait, the smaller the subsidy you will receive.
