Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: It should be low cost. Layman friendly, and easy to build. Must be efficient enough to satisfy the fundamental battery charging needs.
We will start with the simplest circuit ideas for an LED circuit and a solar charger circuit. First, we use a 12V 2.5Ah battery and a 12V 2W LED. The LED consumes about 0.16A (from 2W/12V). At night, we need about 8 hours of light. So, the LED needs about 1.28A in total, or around 50% of the battery capacity. So it should be enough.
The solar panel supplies the peak voltage of 6 V, at 500 ma during daytime, which charges the battery as long as this voltage is available from the solar panel. The resistor Rx keeps the charging current to a safe lower level so that even after the battery is fully charged, the minimal current does not harm the battery.
These solar cells should be able to charge one 1.2 volt, battery, or two 1.2 volt batteries in series at a rate of 20 mA for 200 mAh battery, 30 mA for a 300 mAh battery, or 60 mA for a 600 mAh battery. The charging circuit for these batteries is simple, a solar cell connected to a diode then connected to a NiCad battery.
The 4V level ensures that the battery is never overcharged (at 4.2V) and this also allows the circuit charge the battery without a constant current supply. The following solar powered garden light was designed by Mr. Guido which includes additional features such over charge and low charge cut off for the battery and with a Schmidt trigger.
In the circuit above, the current from the solar cell flows through D1 to charge the Li-ion battery. When there is less sunlight, the higher voltage from the battery cannot flow back to the solar cell. Because there is a D1 blocking it, the current can flow only one way. The energy in the battery is stored and gradually increases until it is full.
