PURPOSE: A solar electric generator is provided to execute high efficiency solar power generation with reducing the volume of a power generator by collecting light through a signal large sized spherical lens without installing a plurality of lenses. CONSTITUTION: A rotator(2) is rotatably installed in a base plate(1) and forms a plurality of helical blades. A photocell(3) is installed in the outer circumference of the rotator by being spaced apart with a uniform interval. A driving part is installed in the base plate and rotates the rotator. A lens(4) is installed by being spaced apart from the rotator and condenses sunlight after refracting the sunlight.
