The amount of energy radiated by the sun onto the earth in just three hours is the same as that used by the world population in a whole year. Our collectors capture this energy and convert it into heat – at one of the best conversion rates you can get. We have the know-how to make wide-area collectors of up to 24 square metres, a size that works far more efficiently than smaller units.

But it is not just the performance of our collector installations that is convincing. They have a persuasively elegant design, a long service life, and can be put to ingenious uses. Find out more in the "Winkler product and service portfolio" section.

Did you know? There are almost 4 million square metres of solar collector in operation in Austria – which is about one and a half times the area covered by the municipality of Weiler.
