5v regulated solar cell power supply circuit diagram

Description: Powered by a solar panel, the circuit provides a 5V pure regulated DC voltage. It consists of an oscillator transistor and a regulator transistor. The solar panel charges the battery when sunlight is sufficient to generate a voltage above 1.9V. A diode is required between the panel and the battery. The circuit is designed to charge a battery from a source with a lower voltage. It should not be used to charge a battery with the same or lower voltage than that generated by the solar panel. This circuit produces three regulated output voltages with a minimal number of electronic components: +12V, +5V, and -5V. Diodes D2 and D3 perform full-wave rectification, charging capacitor C2 during each half of the alternating current cycle. Simultaneously, diode D1 and capacitor C1 are also utilized. The schematic diagram represents a battery charger for a 6V Gel Cell battery type.
