Solar PV for Farms & Barns
Large unshaded roof areas, high self-consumption for machinery and cooling: farms are ideal PV locations.
Typical key figures
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.
