Payback period
40–70 %
Self-consumption

Your benefits at a glance

Large, unshaded surface

Barns offer hundreds of m² of south-facing roof without chimneys or skylights.

High daytime self-consumption

Milking machines, ventilation and cooling run during the day – exactly when the system produces.

ZEV for agricultural operations

Collective self-consumption (ZEV) distributes self-produced electricity across multiple buildings.

Pronovo KLEIV / GREIV

Systems over 100 kWp receive the higher GREIV tariff. No difference from a private home.

Frequently asked questions

Are there special subsidies for farms?

No – Pronovo EIV applies regardless of building type. Systems over 100 kWp get GREIV.

How large for a farm using 120 kWh/day?

For 120 kWh daily we recommend 50–70 kWp in Switzerland.

Do I need planning permission for the barn roof?

For systems not exceeding the roofline, most cantons apply a simplified notification procedure.
