A solar collector is configured for solar radiation absorption and conversion into heat, in either flat panel (10) or 3-D hemispherical, conical or similar format, as a modular laminated sandwich of a translucent outer panel (12,13), such as a single layer or multi-wall sheet, surmounting a profiled backing tray (13), with a channel recess or channel to receive a coiled conduit (11), such as of flexible wall plastics material, for a heat exchange fluid medium, conveniently water, with an optional backing layer profiled for conduit location and support. |
