Solar panel efficiency and security monitoring device

A solar panel monitoring system comprising:

• a photoelectric sensor configured to detect a light level at a solar panel;
• a voltage-based monitoring circuit configured to:
• receive a detected light level from the photoelectric sensor;
• monitor a voltage of the solar panel;
• and
• generate a security alarm signal in response to detecting a reduced voltage of the solar panel while the detected light level from the photoelectric sensor remains constant;
• a solar panel circuit configured to form a closed circuit with the solar panel such that removal of the solar panel opens the closed circuit and generates an open circuit alarm signal;
• a PIR sensor configured to output an infrared alarm signal in response to detecting an infrared signal exceeding a predetermined threshold;
• an RFID reader configured to detect an authorized RFID tag and generate an unauthorized alarm signal in response to a failure to detect an authorized RFID tag;
• a processor configured to, in response to detecting both the security alarm signal and the open circuit alarm signal:
• check the output of the PIR sensor;
• in response to the infrared alarm signal output by the PIR sensor, detect the unauthorized alarm signal;
• and
• in response to detecting the unauthorized alarm signal, transmit a master alarm to a monitoring center.
