Your project in the canton of Valais
Valais follows the Rhône valley from Brig to Lake Geneva, with side valleys climbing up to mountain resorts. The canton is bilingual: French-speaking Lower Valais, around Sion, Martigny and Monthey, and German-speaking Upper Valais, with Brig and Visp. On the hillsides, vineyards surround villages of stone houses and old wooden granaries. Crans-Montana and Zermatt are home to chalets, holiday flats and hotels; in Zermatt, where cars are not allowed, transporting materials requires special arrangements. At altitude, snow and sunshine influence building techniques and the working season. Wherever you live in Valais, you can write your request in English. For a chalet, a traditional mazot or an alteration in an old town, check with your municipality whether approval is needed. Give the municipality and postcode and, in a resort or at altitude, access periods and transport arrangements to the building.
- For a chalet in a resort, note the altitude, the state of the road in winter and your availability for the work.
- In Upper Valais, say whether you are happy to communicate in German.
- For a village house among the vineyards, describe access via the lanes and the space for unloading materials.
Solar installations in the canton of Valais
Valais enjoys a dry climate and some of the highest levels of sunshine in the country. In the Rhône plain, around Sion and Martigny, family homes, halls and greenhouses generate a great deal of electricity, including in autumn. On the vineyard slopes, old mazots and wine cellars call for discreet integration. In resorts such as Crans-Montana or Zermatt, chalets and second homes have to deal with snow, restricted access and seasonal occupancy, so remote monitoring is useful. Façade-mounted panels suit buildings at altitude well. For permits and any conditions on appearance, contact your municipality.
- In Zermatt, plan the delivery of materials with the traffic restrictions in mind.
- For a holiday chalet, consider a battery that stores the electricity produced while you are away.

Frequently asked questions
What should I check before installing solar panels in Valais?
Start by specifying photovoltaic electricity or solar thermal heat. Provide roof orientation, pitch, condition and any shading without climbing onto the roof. For photovoltaics, share electricity use and any battery or charging needs; for solar thermal, describe hot-water demand and the existing hot-water or heating system. Ask which roof checks are needed before equipment is selected.
Which documents help size a solar installation?
Share roof dimensions or plans and describe the intended use. For photovoltaics, provide electricity consumption and major loads such as a heat pump or electric vehicle; for solar thermal, provide hot-water demand and details of the existing system and storage space. Roof condition and shading need site assessment. Ask the installer to explain the sizing assumptions for the selected system.
What should I compare in solar installer quotes?
Compare the equipment and connections for the same type of system: modules, inverter and any battery for photovoltaics, or collectors, heat storage and hot-water or heating integration for solar thermal. Clarify mounting, roof interfaces, monitoring, documentation and commissioning. Ask which procedures apply to your building and who handles them; do not assume eligibility for financial support.
How should I prepare for the solar installer visit or work?
Gather roof or building plans without climbing onto the roof and explain access restrictions. For photovoltaics, note the distribution board and possible cable routes; for solar thermal, identify the existing hot-water or heating equipment and available storage space. Ask the installer to assess connection routes. If roof repairs are planned, agree their sequence before solar equipment is ordered.
