This is the simple solar battery charger circuit. It is suitable for charging one or two 1.2V AA nickel-cadmium batteries or AA Ni-MH batteries. Currently, this type of battery has increased capacity, but the price remains the same. For the worth, we should choose the proper battery, I chose the size 1900mAh to 2400mAh.
Making a solar battery charger from scratch is simple. Connect the solar cells to the TP4056 charger and then the 18650 lithium battery. Use a voltage booster to increase the voltage to 5V DC power. In elaborate words, connect the photovoltaic cells to the TP4056 battery charger unit. Then, tie a 1N4007 diode on the positive connecting cable.
Below is the circuit diagram for it. The solar cells positive terminal is connected through the diode to the positive terminal of the 1.2V battery. If the voltage of the solar cell drops below 1.4 volts then with the 0.2V the blocking diode takes there wont be enough potential to charge the 1.2V 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.
Our inexpensive solar charger project will be an excellent solution for a situation like this to power an Arduino board. This project can also solve the efficiency issue of Arduino when in sleep. Sleep saves battery, however, the sensors and power regulators (7805) will still consume battery in idle mode draining the battery.
