PURPOSE: A drive circuit of a solar tracker for solar power generation is provided to enable a solar cell module drive system to move along the sun with minimizing power consumption. CONSTITUTION: A drive circuit of a solar tracker for solar power generation comprises a first optical sensor(310), a second optical sensor(320), a first resistor(330), a first motor drive unit(350), and a second motor drive unit(360). The first optical sensor senses sunlight and produces first electrical signals. The second optical sensor senses the sunlight and produces second electric signals. The first resistor restricts the current of the first electrical signals outputted from the first optical sensor. The second resistor restricts the current of the second electric signals outputted from the second optical sensor. The first motor drive unit outputs first control signals rotating the motor in the first direction. |
