Battery Charging From Solar Panel Circuit

Place the solar panel in sunlight.

Battery charging from solar panel circuit.

The charger has voltage and current regulation and over voltage cut off facilities. Now set the output voltage by adjusting pot rv1 check the battery voltage using digital multi meter. Battery voltage 12v solar panel 18v. The solar panel consists of solar cells each rated at 1 2 volts.

So thermally it is carefully matched to the current rating. The power produced from a solar panel is usually employed for charging a lead acid battery. The lead acid battery when completely charged is utilized with an inverter for getting the needed ac mains voltage for running the house electrical. In our 4rth automatic solar light circuit we incorporate a single relay as a switch for charging a battery during day time or as long as the solar panel is generating electricity and for illuminating a connected led while the panel is not active.

The solar panel attaching wires. The circuit uses a 12 volt solar panel and a variable voltage regulator ic lm 317. How to operate this solar battery charger circuit. The copper stripboard includes copper tracks rows.

P 18v 12v 1 5a 9w. Upgrading to a relay changeover. Max power comes into effect when charging a 12v battery 1 5a. Give the connections according to the circuit diagram.

The circuit harvests solar energy to charge a 6 volt 4 5 ah rechargeable battery for various applications. Circuit diagram of solar panel battery charger step 1.
