How many watts/volts/amps does a solar panel have to have to power a 12 volt battery?
I am looking to buy a solar panel with:
1. 12 volts
2. 4.5 Watts
3. Up to 250mA- (milli-Amps)?
Do you think this small solar panel will generate enough electricity to charge a 12 volt Sealed lead acid battery?
Sorry, to charge a battery, not power a battery.
wish I knew what your battery is trying to supply?
you need a higher amperage to be effective more between 2 to 10 amps @ a very basic level . I have several batterys tied together and require a lot more wattage and amperage in order for my system to keep up enough power in my batterys to supply my needs.
