A solar power generating apparatus has a transparent isolating layer made into a hollow cone having a smaller top and a larger bottom. The isolating layer has a hole at the top thereof and a space therein. A heat absorption layer is provided at an inner side of the isolating layer to absorb heat of the sunlight and to heat air in the space of the isolating layer. A rotary device is pivoted on the isolating layer at where adjacent to the hole. The heated air generates an upward airflow in the space of the isolating layer to drive the rotary device for rotation.
