Solar Air Collectors

Early December, outside temperature 6C/43F. Two simple air collectors and ventilators. Max output temperature: 62C/143F

[mahnecke.de] – Solar air collector project in northern Germany

Still waiting for the first solar air collector project where the black absorber back plate consists of a black solar panel. The collector should be constructed as such that the glass/acryl cover can be removed in the spring and put back again in the autumn to avoid too high solar panel temperatures during the summer. Special construction absorber with window screen.
