Regulations vary depending on the zone and the appearance of the building. In the canton of Aargau, you should consult local authorities to confirm whether a notification procedure is sufficient or if a formal building permit application is required, especially in protected areas.
A well-maintained solar thermal installation typically has a lifespan of 20 to 25 years. Regular maintenance by a professional is recommended to ensure the system operates correctly and to maintain optimal thermal efficiency over the long term.
In winter, production decreases due to reduced sunshine. However, solar collectors remain useful as a supplement. They do not replace the main heating system, but contribute to reducing overall energy consumption throughout the year.
To get a realistic price range adapted to your specific needs, use the RenoIndex estimator. This free online tool allows you to calculate the costs for renovation and energy installation work in just a few clicks, according to current Swiss standards.
