A solar panel that utilizes the sun's rays to heat a liquid to be used for providing heat or hot water includes front and rear parallel but spaced apart clear plastic panels. Each panel has a front surface, a back surface and left and right side edges. The front panel is intended to face the sun and is substantially transparent so that the sun's rays can pass therethrough. The rear panel has a reflective coating thereon wherein rays from the sun that pass through the front panel and through the space between the panels is reflective back toward the space. Located within the space between the panels are a plurality of conduits formed by a plurality of internal walls that extend between the front and rear panels and between the left and right side edges. Within the conduits is a darkened oily liquid that is heated by the incoming rays of the sun and by the rays reflected by the rear panel. In a preferred embodiment, the front and rear panels and the internal walls are extruded as a single unit.
