Hybrid solar panels to replace an oil furnace – Valais (CH)
Since moving into their house 20 years ago, the Bernard family has undertaken numerous renovation projects to transform their home into a passive house.
The Bernards started by insulating the house and installing triple-glazed windows. They then replaced their fuel boiler by a natural gas boiler. Now, they have decided to install DualSun 2-in-1 panels to generate both electricity and hot water for their home!
