Renovations, heritage and volumes
For your renovation projects in Solothurn, the federal building register (RegBL) indicates that 3 buildings are listed under heritage protection, requiring early coordination with the municipality for permit applications. The building volume data covers 1517 houses with a median volume of 462 m3 according to the SIA 416 standard, which is essential for scaling your heating and insulation upgrades. Please note that data coverage is partial, as 1514 buildings are recorded under unknown or other standards. Since renovation year data is not available, you should conduct a thorough on-site assessment to accurately plan your specific property improvements.

Why choose solar thermal energy?
Solar thermal collectors are an efficient solution for converting solar radiation into heat. These systems are primarily used for domestic hot water production.
In Switzerland, solar thermal collectors usually cover much of summer hot water, thus reducing the load on your main boiler. This technology provides increased independence from rising fossil fuel prices.
It is a sustainable investment that improves your home's energy class over the long term while actively participating in the Swiss energy transition.
Planning your solar installation
A high-performance system relies above all on a rigorous sizing study. It is essential to accurately calculate your hot water needs based on the number of occupants and the available roof surface.
If you are considering moving towards a hybrid system, be aware that combining collectors with a heat pump needs a sizing study to ensure optimal compatibility.
Proper planning avoids oversizing, which can reduce the overall efficiency of the system, and ensures consistent heat production throughout the year.
Subsidies and financial support
Although rules vary by region, the national Buildings Program regularly encourages energy efficiency measures. It is crucial to submit your grant application before starting the work, as subsidies are generally not retroactive.
Check with the relevant cantonal services to find out the current eligibility criteria and maximize your chances of obtaining financing for your solar project.
Hiring a professional
Installing solar thermal panels requires high technical expertise to ensure roof tightness and hydraulic safety. Hiring a certified installer is essential to guarantee compliance with current standards.
A professional can not only advise you on the most suitable equipment but also provide the preventive maintenance necessary for the long-term operation of the installation.
Never neglect installation quality, as it directly determines the energy efficiency of your solar system for decades to come.

Frequently asked questions
Do I need a building permit?
Requirements vary depending on the building type and location. It is advisable to contact local authorities to check specific urban planning conditions. Some projects may be exempt, but others require prior authorization to ensure compliance with aesthetic rules.
How long does installation take?
The installation itself usually takes a few days, depending on the roof complexity and the hydraulic system. However, the planning phase and obtaining permits can extend the project. A professional will provide you with an accurate timeline when providing the quote.
Does solar thermal work in winter?
Yes, the system works as long as there is solar radiation, even in cold weather. However, the yield is reduced compared to summer due to shorter sunlight duration and the sun's angle. A complementary system is often necessary.
