Payerne, Moudon, Avenches, Lucens, Domdidier — rural Switzerland and its large rooftops.
The Broye, shared between Vaud and Fribourg, is farming country par excellence — and therefore ideal terrain for solar. Between the large farms of the plain, the sheds and the historic towns of Payerne, Avenches and Moudon, clear and well-oriented rooftops are everywhere. We work here on both individual homes and farm buildings, handling the paperwork on the Vaud side as well as the Fribourg side.
Service area
Local context
A continental plain climate: hot, sunny summers, with possible fog in autumn and winter. Solar output of 950 to 1050 kWh/kWp. Air/water heat pumps work well all year, as the recent individual housing stock is often already well insulated.
A very agricultural region: large farms, sheds and outbuildings with vast, unshaded rooftops, perfect for medium- and high-power solar. Added to this are the growing residential housing around Payerne and Avenches, and the historic centres (Roman Avenches, Payerne abbey) where integration must stay discreet.
Grid operators are Groupe E on the Fribourg side (Domdidier, Cugy) and Romande Energie on the Vaud side (Payerne, Moudon, Avenches). We tailor the connection paperwork to the operator concerned. Typical times: 3 to 6 weeks.
I.ON advice
The farm and shed rooftops of the Broye allow high-power installations with an excellent return on investment, especially where the farm consumes during the day (drying, ventilation, milking, refrigeration). We handle the structural study and the agricultural subsidy paperwork.
Depending on whether your property is on the Vaud or Fribourg side, subsidies and procedures differ. We always identify the most advantageous programme for your municipality — a real asset in a region where the cantonal border runs through many villages.
In the many recent developments around Payerne and Avenches, pairing solar, heat pump and EV charger from the outset maximises self-consumption and ROI. Plan the SG-Ready link from the moment the PV is installed.
2026 subsidies
Federal grant for any new PV installation: around 320-380 CHF/kWp for small systems (<30 kWp), paid once after commissioning. For an 8 kWp system: ~3,000 CHF.
On the Vaud side (Payerne, Moudon, Avenches) as on the Fribourg side (Domdidier, Cugy), the cantons support PV and heat pumps through their respective programmes. We prepare the file matching your municipality.
The net cost after subsidies is deductible from taxable income as an energy investment in both cantons. The saving depends on your marginal rate.
Exact amounts vary from year to year and depend on the specifics of each project. We always calculate the maximum combination of grants available when preparing your quote.
