The patent filed by Northrop Grumman Corp describes a reconfigurable solar array that includes a plurality of photovoltaic cells and an interconnect circuit with switches for connecting the cells. A thermostatic feedback control circuit, in communication with a temperature sensor, produces a temperature signal proportional to the cells' temperature. This circuit causes switches to change state at a preset temperature, independent of supply voltage. The array configures the cells in parallel strings when the temperature is high and reconfigures them in series when the temperature is low, optimizing energy production.
Furthermore, the patent details a method for operating the reconfigurable solar array, involving producing a temperature signal proportional to the cells' temperature and setting switches in different states based on the temperature. The method ensures that the photovoltaic cells are arranged optimally to receive and convert solar radiation signals into a stable direct current (DC) signal. By reconfiguring the cells in parallel or series based on temperature, the system maximizes energy efficiency and output, showcasing an innovative approach to solar power generation.
