This is a great a simple Solar Battery Charger circuit. The most simple power systems with solar panels are composed of 3 parts: a diode, a solar cells system and a rechargeble battery. The diode prevents the battery discharging through the solar cells in the lack of solar light. Although the diode is often a Schottky type, the direct voltage applied on it can produce a high power leakage.
The featured solar battery charger circuit presented here uses a special diode with reduced direct voltage.
