<p>A solar collector is constructed on a support structure (such as a roof (14)) that has a plurality of side-by-side channels (16) (for example formed between roof battens (20)), using a length of an elongate web (26) of flexible material that is formed with a plurality of generally parallel passageways for a thermal transfer fluid extending in the longitudinal direction of the web and spaced apart across the width of the web. A first run (26c) of the web is laid along a first of the channels of the support structure so that one face of the web faces out of said first channel. The web is split longitudinally between at least one adjacent pair of the passageways adjacent and beyond the end of said first run and is curved so that the web enters a second of the channels of the support structure. A second run (26d) of the web can then be laid along the second channel so that said one face of the web faces into said second channel.</p> |
