The present invention relates to a solar collecting and utilizing device comprising: a paraboloidal mirror for collecting the sunlight and converging it as a facula, a sunlight collector, a solar storage and conversion device, and a solar tracking equipment, wherein, said solar tracking equipment comprises implementing mechanical parts and photoelectrical control parts; said sunlight collector includes a light guider which converts the facula into substantially parallel light beams and reflects them in a desired direction, and a curved surface condenser mirror which receives the substantially parallel light beams reflected from the sunlight guider and converges them into solar storage and conversion device; said light guider includes a light guider mirror for point focusing the light beams. The present invention provides a device which can enhance highly the solar collection density, centralize the energy conversion/utilizing points, simplify the sunlight tracking mechanism, improve the mechanical reliability of the whole system, and lower the investment and the cost of operation.
