The invention advances a solar energy tracing power storage system and its use, mainly including a solar energy board, a gear running mechanism, a PV in-situ fixer, a control box as well as solar controller, azimuth meter, inclinometer, guard against theft apparatus and storage cell in the control box, GPS receiver, photosensitive switch, anemometer, etc; when installed on the top of automobile, the mechanisms in the control box, GPS receiver, photosensitive switch and anemometer are all in an operating state, when the brake is pull up, the microprocessor receives the position coordinates of the system and azimuth moving data from the GPS receiver and azimuth meter, and the sun position coordinates calculated by the microprocessor are observed by PDA externally linked with the microprocessor, and when the photosensitive switch and anemometer inspect the outside light brightness and the wind speed is allowable, the motor controller drives the gear running mechanism to trace the sun; and the charging and discharging solar energy are controlled by the solar energy controller, and when unallowable, the gear running mechanism stops running and returns, and once allowable, continues running. |
