A light weight, high efficiency solar energy collector which utilizes a shallow, open-topped, foamed, integrally skinned or otherwise sealed plastic vessel with a multiple layer, light transmissive cover is described. The cover is sealed to the inner edges of the continuous rim of the vessel to contain a liquid energy absorbing material which is circulated in the vessel in contact with the lower surface of the innermost cover layer. An optically opaque, preferably black, liquid is utilized as the absorbing material which is circulated in direct optical and physical contact with the cover and then to a heat exchanger immersed in a heat storage medium to release its collected energy for later use.
