A solar cell power system can be built using this electronic scheme. This electronic circuit is composed of three parts: a diode, solar cell panel and a rechargeable battery. Diode prevents battery discharge through the solar panel in the absence of sunlight or low light. Although diode is usually Schottky type, the direct voltage it can produce a considerable energy loss. Circuit uses a specials diode with low direct voltage.
A Simple Solar Cell Power System Circuit Diagram:
To adjust the circuit, replace solar panel with adjustable stabilized voltage source, with current limiter set at a level which is not dangerous to the battery. Adjust power supply hasil at a level higher than 0.1 V than battery voltage. Then, adjust P1 until the point where IC1's hasil went into logical "1danquot;.
Finally, with an ammeter if the battery is discharged when the source voltage is below the current battery voltage.
