The solar energy absorber and fluid heater comprises a plurality of apertured hollow black balls disposed in a container of fluid to be heated, for example, as a layer along the bottom surface thereof. The sun's rays pass through the fluid and are absorbed by the surfaces and walls of the balls. The heated balls produce a flow of heated water throughout the container to heat all of the fluid therein. The solar energy absorber may also be a flat, dark colored plate which itself may carry apertured, fluid-receiving chambers.
