The invention provides a solar streetlamp controller and a solar streetlamp using the same, wherein the controller is used for realizing coordination work of a solar photovoltaic cell, a storage cell and an illuminating load; the control comprises a time servo module used for providing accurate time information and setting streetlamp illuminating time, a photo-sensitive detection module used for detecting optical luminance of a surrounding environment, a discharge control module used for generating a turn-on control signal to be sent to a discharge driving circuit according to the set illuminating time information and the optical luminance of the surrounding environment, and a discharge driving module used for driving a power supply system to supply power to the illuminating load according to the turn-on control signal of the discharge control module. The solar streetlamp controller provided by the invention adopts a manner of combining the photo-sensitive control with the time control, so that the daybreak time can be accurately identified in all mornings of all kinds of weather so as to reasonably control the illuminating time of the streetlamp in mornings; and therefore, the solar streetlamp controller has a relatively good energy-saving effect, and can be widely applied to illumination for various roads.
