Renovations, heritage and volumes
For your renovation projects in Au, data from the federal building register indicates that at least 9 buildings are subject to heritage protection, requiring early coordination with the municipality to secure necessary permits. Please note that data coverage is partial for certain indicators: information regarding the year of renovation and building volume according to the SIA 416 standard is not available in the current records. We advise you to verify these technical specifications directly with local authorities before proceeding with modernization plans or insulation upgrades to ensure your project aligns with municipal requirements and building standards.

Administrative steps and permits
However, it is advisable to check cantonal and local guidelines before signing any quotes. Ensure that your installer provides all necessary technical documentation to assist with this administrative step.
To anticipate costs related to these procedures and the equipment, the RenoIndex simulator remains your best partner for a reliable price estimate.
Available financial support
Investing in solar energy is encouraged at the national level. The federal one-off remuneration via Pronovo helps to significantly reduce the initial investment for small systems. These subsidies are designed to support homeowners in their energy transition.
Although conditions vary, these mechanisms ensure better economic attractiveness for your renovation. It is important to submit your application according to current guidelines.
If you wish to visualize the impact of these subsidies on your total budget, our RenoIndex tool allows you to obtain a clear and fast cost estimate for your project in Au (SG).
Choosing the right installer
The success of your photovoltaic project depends on choosing a qualified installer. A good professional does more than just install panels; they analyze your roof, assess shading, and optimize energy yield.
Do not hesitate to request several detailed quotes to compare services and equipment brands. Ensure that the company has the necessary certifications to operate in Switzerland.
Before you begin, use the RenoIndex calculator to check if the quotes you received are in line with the local market average. This guarantees peace of mind throughout your renovation.

Frequently asked questions
What subsidies can I get for solar?
At the national level, the one-off remuneration managed by Pronovo is the main subsidy for small systems. It helps cover a portion of your investment costs. We advise you to consult their official portal before starting your work to check the current eligibility conditions.
Is a building permit required?
Generally, a suitably integrated roof installation only requires a notification procedure. This simplifies your administrative steps. However, always check local specificities with your municipality, as rules regarding heritage or landscape protection may apply in certain areas.
How to estimate the total cost of my project?
Use the free RenoIndex simulator. By entering a few details about your home, you will instantly get a realistic price range adapted to the local market, which will help you budget your solar installation with peace of mind.
Does profitability depend on the sun?
Yes, but mostly on your ability to consume the electricity produced. The more you self-consume, the less you buy from the public grid, which improves profitability. Correct sizing based on your consumption profile remains the determining factor.
