Operation principle:
Winter sunrise evening, sunset early, the hours of daylight is short; Summer sunrise early, sunset evening, the hours of daylight is long, the rule that this hours of daylight that is people grasp very early changes according to seasonal variations.
From above principle, in advance according to the sunset of locality with at sunrise, be the keying program of function establishment motor with time, program is input in the memory through USB interface, carry out the output motor turn signal to drive circuit by the single-chip microcomputer in the control circuit.Through steering mechanism drive photovoltaic battery panel along with the time along continuous straight runs rotating certain angle.
Pass through program control device; Can be controlled at motor in the Various Seasonal moves consistent according to the angle that starts between at sunrise and the control photovoltaic battery panel turns over sunlight; Photovoltaic battery panel can begin to turn between at sunrise automatically, stops operating at post sunset, utilizes solar energy fully.
One cover program control device can be controlled a plurality of photovoltaic battery panels and rotate synchronously.
