The invention discloses a spherical solar lighting system which comprises at least one solar panel connected with an inverter, and the solar panels are all spherical solar panels which are connected in series to form a spherical solar battery array. The spherical solar lighting system comprises the spherical solar panels, a charge controller, a storage battery set, an inverter AC output, and the like and is a device for improving the solar generation convert ratio. The spherical solar lighting system learns the advantages of the prior solar panels and overcomes the defects of angle consideringand fixed lighting of sloping solar panels and lean-to solar panels. The spherical solar lighting system uses the spherical solar panels, though a sun angle tracking device is not used, the sphericalstructure of the spherical solar lighting system can guarantee that a half sphere is always under the irradiation of sunshine at any time under the condition that the sunshine exists, thus the stability of absorbing solar energy can be guaranteed.
