<p>PURPOSE:To conduct waste water treatment surely, to utilize solar energy effectively and to facilitate execution and maintenance. CONSTITUTION:A plurality of bearing materials 1 are disposed along the eave ridge direction, a plurality of water flowing boards 2, in which left and right side edges are erected, are arranged among the bearing materials 1, 1, and a light-transmitting material 3 is disposed to the upper sections of each water flowing board 2, thus forming a plurality of heat collecting spaces 4. A plurality of the heat collecting spaces 4 are communicated on the ridge side and the eave side while a warm-water heat collector 50 is mounted to at least a part.</p> |
