What grants are available in the canton of Bern?
Grants for solar thermal in the canton of Bern depend on the current programs. They are generally granted as amounts per square meter of installed collectors. We recommend checking the official website of the canton to know the eligibility conditions before starting your project.
Can solar be combined with a heat pump?
Yes, this is an excellent solution for optimizing your home's energy efficiency. However, combining these two systems requires a precise sizing study to correctly balance energy inputs and ensure optimal management of your hot water production throughout the year.
