1 X 10.72 Volts Solar Panel http://amzn.to/2qnnC83
12 Volts Solar Panel http://amzn.to/2AnbPq5
15 Volts Solar Panel // you choose any one
2 X 4700uf 25v
3 X LM7805 Voltage regulator
3 X USB Connector
3 X 4148 Zener Diode
1 X Heatshink
The circuit is very simple to make you can use PCB for this project.
Follow the circuit diagram step and build the circuit. This is very simple voltage regulator LM7805 .
First make circuit than fix the heatshink. If your Solar Panel makes Ac voltage so connect 1N4007 Diode in starting of connection.
Know More Voltage Regulator
Linear Regulators. One of the most basic ways to regulate voltage and provide a stable voltage for electronics is to use a standard 3-pin linear voltage regulator such as the LM7805, which provides a 5 volt 1 amp output with an input voltage at up to 36 volts (depending on the model).
So Friends if yore solar smartphone charger work well, than comment and any problem also comment me.
