The invention provides a solar cell panel detection and control system, which comprises a control center, a sensor monitoring module, a data transmission module, a C++ upper computer module and a control module. The control center is a central processing unit. A light sensor, a temperature sensor, a tilt sensor, a photoresistor and a signal processing circuit thereof forms the sensor monitoring module. The data transmission module is used for RS232-to-USB communication. The C++ upper computer module mainly displays real-time data detected by the sensors, makes effective statistics of the data and alarms against standard-exceeding data. The control module comprises adjusting buttons used for adjusting a solar cell panel manually.
