Solar Charging: It can output a stable voltage value when the input voltage changes which is very suitable for solar energy systems such as solar charging, solar power supply, solar voltage conversion.
The regulated solar power supply designed in this project provides regulated and adjustable voltage from 1.1V to 10.4V by varying the potentiometer RV1. Therefore any battery or load circuit that needs a voltage between 1.1V to 10.4V can draw power from this circuit.
Once the voltage drawn from the solar panel is regulated to desired levels it can be utilized for powering load circuits. In the project, the regulated voltage is utilized to charge a battery. The project involves deriving DC voltage from the solar panel, regulating input voltage, voltage adjustment, and back current protection.

The LM-317 IC is used for the voltage regulation while a variable resistor is used for setting the output voltage to desired levels.
In this project, the solar energy will be tapped using a solar panel and it will be regulated to charge a 3.7 V battery. The 15 Watt solar panel used in the circuit has a DC output voltage of approximately 22 V. The DC output from the solar panel is not regulated and needs to be made ripple free using a voltage regulator.
