what size solar panel do i need to charge a 110ah battery
The time it takes for your solar panel to charge your battery depends on the current of the panel you choose. As battery capacity is measured in A/h (amp-hours), you need to know the solar panel current to estimate how quickly it will charge your battery.For example, A 100W motorhome solar panel normally produces 4-5A per hour in bright sunshine.If you have a 100A/h battery, this will take approximately 100/5 = 20-25 hours of sunshine to charge from 0% to 100%. The current of 12 volt solar panels or charging kits is typically proportionate to their wattage.s battery capacity is measured in A/h (amp-hours), you need to know the solar panel current to estimate how quickly it will charge your battery.
