Abstract: A system for monitoring efficiency and security of a solar array includes a voltage-based monitoring circuit and a photoelectric sensor. The system detects a voltage across the solar array and compares the voltage to changes in light detected by the photoelectric sensor. In response to reduced light detected at the photoelectric sensor, the system generates a low-efficiency alarm. In response to reduced voltage while light detected by the photoelectric sensor remains constant, the system generates a security alarm signal. The system may also include a PIR sensor, an RFID reader, and a solar panel circuit including the solar panels of the solar array. In response to an infrared alarm at the PIR sensor, an unauthorized alarm at the RFID reader, and an open circuit alarm signal of the solar panel circuit, and the security alarm signal, the system may transmit a master alarm to a monitoring center.

Abstract: Techniques for managing a fuel for a power generator include storing a volume of a fuel in a primary fuel storage tank that includes an inlet and an outlet; generating electrical power with a solar power assembly; operating a pump assembly with the generated electrical power to circulate a flow of the fuel from the primary fuel storage tank to a fuel filter; removing at least a portion of contaminants from the flow of the fuel; circulating the flow of the fuel to a fuel quality sensor; measuring a quality value of the flow of the fuel; and based on a signal from the fuel quality sensor associated with the quality value of the flow of the fuel, operating a control valve to direct the flow of the fuel from the fuel quality sensor to the primary fuel storage tank from the control valve or an auxiliary fuel storage tank from the control valve.
