Solar thermal collectors capture energy from the sun to heat a transfer fluid that transmits heat to your hot water tank. This is an excellent way to reduce your dependence on fossil fuels.
Solar thermal collectors usually cover much of summer hot water needs efficiently. In addition to lowering your bills, you increase the value of your property.
To assess the budget required for installing this system, use the free RenoIndex calculator now to get a reliable cost range.
Sizing and integration
The success of a solar project depends on rigorous sizing. Combining collectors with a heat pump needs a sizing study to ensure performance. This step guarantees that the system is properly calibrated to cover your needs without overspending.
Well-thought-out sizing allows for optimal synergy between the different energy sources available in your home.
To get a price range adapted to your specific situation, do not forget to consult the RenoIndex service, which will help you budget your renovation work effectively.

Frequently asked questions
What subsidies are available for solar water heating?
Subsidies for solar water heating vary by canton. Several cantons subsidise collectors per m² or via a flat-rate installation bonus. It is important to check the latest guidelines of the canton of Zurich before starting your work to know the exact amounts and current eligibility conditions.
How long does a solar water heating installation take?
A standard installation usually takes a few days. The time depends on the complexity of your roof and the integration with your existing heating system. A preliminary study helps minimize construction time. To estimate your overall budget, use our free RenoIndex tool.
Is it cost-effective to combine solar and heat pumps?
Yes, this combination is very efficient. However, it requires a specific sizing study. Solar collectors provide hot water during the summer, allowing the heat pump to remain off. Get a cost estimate on RenoIndex.
What is the ideal orientation for the panels?
South orientation is ideal for capturing maximum sunlight and maximizing yield. However, other orientations can work depending on the pitch of your roof. Your installer will be able to validate the optimal configuration for your project. Consult RenoIndex to price your work.
