Benefits of Solar Thermal
Solar thermal collectors are an excellent solution to complement your existing heating system. They usually cover a large portion of your hot water needs during the summer months, significantly reducing the strain on your main boiler.
Besides achieving substantial savings on your annual energy bill, you gain independence from fluctuating fossil fuel prices.
This is a sustainable investment that also improves the energy rating of your building, which is an increasingly crucial factor in the current real estate market. It represents a reliable and durable solution for your water heating needs.
Sizing and Integration
The success of any solar project relies on careful planning. If you are considering combining your new solar collectors with a heat pump, it is important to know that this requires a rigorous sizing study.
A poorly calibrated installation risks being inefficient or overly expensive. It is essential to consult a qualified professional to assess your real hot water consumption needs and the available surface area on your roof.
To get a reliable initial budget estimate before contacting local contractors, make sure to use the free RenoIndex estimator.
Financial Support and Grants
These incentive measures aim to accelerate the energy transition and make renewable energy more accessible to homeowners. While specific policies can vary, be sure to check the programs available at the cantonal level before starting your work.
For a quick overview of your investment and a clear cost estimate, feel free to use the RenoIndex tool.
Maintenance of your Installation
Once installed, solar thermal panels require regular maintenance to guarantee their efficiency over the long term.
Although robust, systems must be periodically checked by a professional to ensure the tightness of the circuits and the quality of the heat transfer fluid.
Regular maintenance not only extends the lifespan of your equipment but also maintains optimal energy yield. By investing in quality maintenance, you protect your initial investment.

How long does an installation take?
The actual installation on the roof usually takes a few days. However, planning and commissioning can take several weeks depending on the system's complexity.
Can solar thermal heat the house?
