Commercial solar in the Canton of Appenzell InnerrhodenOwn power at new builds.

Rules for businesses in Appenzell Innerrhoden

In the Canton of Appenzell Innerrhoden, new buildings must produce part of their electricity themselves, for example with a photovoltaic system. For commerce, industry and farming, the solar system is therefore usually part of the building project. The details are set out in the cantonal Energiegesetz and Energieverordnung. We size the system so that it meets the requirement and fits your consumption.

For existing buildings, the canton provides a notification procedure (Meldeverfahren) under Art. 18a RPG for roof systems that are sufficiently well integrated. It offers an application and notification form with an information sheet. A building permit is needed if the system is not on the roof, is not sufficiently well integrated, affects a protected building or lies in a protection zone. We clarify this before the quote and submit the documents.

Subsidies and one-off payment

The federal government pays the one-off payment (Einmalvergütung) through Pronovo, graded by system size. We submit the application and, on request, pre-finance the subsidies. We did not find direct cantonal contributions to photovoltaic systems on the canton’s subsidy page. Whether the commune or the energy supplier pays, we check when preparing the quote. For depreciation in business assets, your tax adviser can advise you.

Self-consumption in your business

Appenzell Innerrhoden lies in the Alpine foothills, so snow can lie on the modules in winter. For halls and barns, wind and sloping sites are also part of checking the roof and structure. We match the tilt and mounting structure to this. Many businesses in the canton, from trades to farming, use their power during the day. The calculation with your load profile shows which system size pays off. A battery storage unit raises self-consumption further.
