A solar collector has a nonlinear collecting surface, for example, a substantially spherical surface, such collector being positioned perpendicular to the rays of the sun throughout the day thereby providing a constant level of solar energy collection. The collector has a hollow body where absorption of the collected heat takes place by a heat transferring fluid being either a liquid or a gas. Provisions are made for increasing the absorptive efficiency of the collector and for reducing radiant heat loss.
