Your project in the canton of St. Gallen
The canton of St. Gallen almost entirely surrounds the two Appenzells and stretches from Lake Constance to Lake Zurich. The city of St. Gallen is known for its old town with oriel-windowed houses and for many buildings from its textile era. Rapperswil and Jona, on the shore of Lake Zurich, combine a historic centre with newer residential districts. Wil and Gossau are busy regional centres, while in the Rhine Valley, Altstätten and Buchs lie close to the Austrian border. The Toggenburg, around Wattwil, is a hilly landscape of farms and timber chalets. The canton is German-speaking, but your request can be written in English. For an old house in a town centre, ask your municipality whether the planned work requires approval. Give the municipality and postcode and describe building access, whether the project is in town, by the lake or in the Toggenburg.
- For an oriel-windowed house in St. Gallen's old town, attach photos of the façade and windows.
- In the Toggenburg, say whether the house is isolated and how it can be reached in winter.
- On the shores of Lake Zurich or Lake Constance, describe access to the plot and the space available for materials.
Solar installations in the canton of St. Gallen
The canton of St. Gallen stretches from Lake Constance to the Alps, with varied solar needs. In the city of St. Gallen, buildings in the old town and the houses around the abbey call for discreet solutions, often on outbuildings. In the Rhine valley, towards Altstätten and Buchs, industrial halls and greenhouses provide large surfaces for production. In the Toggenburg, around Wattwil, farms and timber houses benefit from combining panels with wood heating. Condominiums in Rapperswil-Jona are interested in sharing electricity between neighbours. Your municipality will explain the steps to follow for your particular property.
- For a greenhouse or a hall, ask for a study of the permissible load on the lightweight roof.
- In the Toggenburg, plan how the panels will be maintained if the roof is difficult to reach.

Frequently asked questions
What should I check before installing solar panels in St. Gallen?
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.
