120 watt solar panel charge 12v battery.

Besides a solar panel the following items are also required. A 12v solar panel is designed to output at least enough voltage to charge a 12v battery under worst case conditions low light level high temperature etc. Use a 10 watt solar panel to charge 12 volt batteries. So lets be practical about that.

This panel will generate more power which will make a battery recharge faster. So if you have a 12 volts battery with a capacity of 10 amps then it can supply about 120 watt hours of service depending on rate of discharge etc one important consideration in solar charging systems is the variable nature of solar power clouds shadows sun angle and dust etc can greatly reduce the voltage output of the panels. So something like a 150 amp hours battery or battery group will be plenty for this single 120 watt solar panel. So with a 10 watt panel.

Being able to generate energy without using gas generators is pretty darn cool and if you re working on a project at home or want to charge a 12v battery without using regular ac outlets and battery chargers a 10 watt solar panel can be the perfect solution.
