Learning to build a solar installation

On Saturday I went to the ecological association called Sebasol in order to learn how to build a solar installation in order to heat water or help heating the house.

It was very interesting and in addition showed that the challenge is completely possible for everyone who does not have two left hands.

As a reminder, in Switzerland a Solar system can cover 80% of the energy required to heat water and 40% of the heating energy. This is a non-neglectable reduction of CO2 and a financial economy.
