Yes, solar thermal collectors work even in cold weather as they capture solar radiation rather than ambient temperature. However, their efficiency is lower in winter due to shorter daylight hours and the sun's lower angle, meaning that a backup heating system is usually required to maintain consistent water temperature.
A well-maintained solar thermal installation generally has a lifespan of between 20 and 25 years. Regular maintenance by a professional ensures that the hydraulic circuit functions correctly and prevents premature wear of the system's main components, thereby guaranteeing optimal performance over the long term.
In Switzerland, installing solar collectors on a roof is generally subject to a notification procedure with your municipality. It is advisable to contact the local administration in Schwyz to check the specific requirements, especially if your building is protected or located in a historic zone.
Costs vary depending on the size of your installation and the complexity of the work. To get a price range tailored to your home in Schwyz, we recommend using the RenoIndex estimator. This free tool will help you plan your budget before contacting local professionals for detailed quotes.
