Abstract
The invention relates to a solar collector (1) comprising a collector element plane comprising a set of parallel metallic collector elements (2) for collecting solar energy. The collector element plane, on its side to be arranged to face the sun, comprises a set of parallel, elongated ridges (R, r) formed by the metallic collector elements (2), and elongated depressions (v) between the ridges (R, r), and that at least some of the ridges (R, r) comprise therein a channel (3) for a heat transfer medium. The invention also relates to a collector element. The invention further relates to a building roof, a building, and a solar energy recovery system comprising said solar collector (1).
Claims22
A solar collector (1) comprising:
- a collector element plane comprising a set of parallel metallic collector elements (2) for collecting solar energy, wherein the collector element plane, on its side to be arranged to face the sun, comprises a set of parallel, elongated ridges (R, r) formed by the metallic collector elements (2), and elongated depressions (v) between the ridges (R, r), wherein at least some of the ridges (R, r) comprise therein a channel (3) for a heat transfer medium;
- and
- a substantially solar radiation permeable coating (4) on top of the collector element plane, which forms at least a part of an outer surface of the solar collector (1), and one or more air gaps (5) provided between the coating and the ridges (R) of the collector element plane inside of which a channel (3) is provided, the coating (4) being supported at least on bottoms of the depressions (v), the coating (4) comprising on its side to be arranged to face the sun elongated ridges into the inside of which the ridges (R) of the collector elements extend, and elongated depressions between the ridges, which extend into the inside of the depressions (v) of the collector elements (2).
