Solar thermal collectors capture solar radiation to heat a heat-transfer fluid, which then transfers the energy to your hot water tank. These systems are particularly effective during sunny months.
In fact, solar thermal collectors usually cover much of summer hot water, reducing the load on your main boiler. It is essential to orient your panels well, ideally towards the south, to maximize the system's energy efficiency.
A preliminary study helps determine the number of panels needed according to the size of your household and ensures optimal coverage.
Integration and sizing
For optimal comfort, the question of coupling with other systems arises quickly. Combining collectors with a heat pump needs a sizing study to ensure compatibility between both technologies.
This hybrid approach guarantees constant hot water all year round, even when sunlight is lower. A qualified installer can evaluate your roof configuration and the current energy demand of your building to avoid costly over-sizing.
A well-sized system ensures a quick return on investment for your home in Rorschacherberg, as it significantly improves the efficiency of the entire setup.
Energy grants and subsidies
Gallen, it is advisable to check the current programmes before signing any quote. Subsidies vary based on the technical performance of the chosen equipment. Make sure to submit your grant application before starting installation work.
In addition to direct grants, tax deductions are sometimes possible; consult the relevant authorities to optimize your renovation budget.
Choosing the right contractor
The success of your project depends heavily on the quality of the installation. It is recommended to request several detailed quotes from certified companies in the field of solar thermal energy.
Check their experience, membership in professional associations, and ask for local references. A good professional does not just install panels; they also advise you on architectural integration and long-term maintenance.

Frequently asked questions
Does solar thermal work all year round?
Yes, but its efficiency varies. In summer, it can cover almost all of your hot water needs. In winter, it acts as pre-heating, requiring a boost from your boiler or heat pump. This allows for significant savings throughout the year despite lower production during the cold season.
How many panels are needed?
The number depends on your hot water consumption and the number of people in the household. On average, a surface area of 4 to 6 m² of collectors is sufficient for a standard family. An installer must conduct a technical study to precisely size the surface area according to your specific needs.
What grants are available in Rorschacherberg?
In the canton of St. Gallen, subsidies are often granted for solar installations. The amounts depend on the current programmes. It is imperative to check the official cantonal grant portals before starting your work to know the eligibility conditions and submit your application on time.
How to estimate the total project cost?
The cost varies depending on the chosen technology and the complexity of the installation. Use our free RenoIndex estimator to get a realistic price range adapted to the Swiss market. This will give you a solid basis for comparing quotes from local artisans before you get started.
