A solar collector has a body member in the form of an inverted frustum of a cone provided with an upwardly opening recess. A light absorbing layer conformingly covers the frustoconical surface of the recess, with a tube being coiled so as to spiral along the light absorbing layer and permit a heat transfer fluid medium to be passed through the recess. Solar radiation impinging on the body member is dispersed throughout the recess by a reflective cone, the base of which abuts the smaller base of the body member and extends upwardly toward the open top of the recess, while the top of the recess is enclosed with a transparent or translucent cover in order to retain heat energy within the recess of the body member. The body member itself is constructed from a thermally insulating material.
