You need around 350 watts of solar panels to charge a 12V 120ah lithium battery from 100% depth of discharge in 5 peak sun hours with an MPPT charge controller. Full article: Charging 120Ah Battery Guide What Size Solar Panel To Charge 100Ah Battery?
Solar Panel Sizing: For a 100Ah battery, a solar panel between 200W to 400W is typically recommended, depending on daily energy consumption and local sunlight availability.
The size of the solar panel needed to keep a car battery charged depends on a variety of factors like the solar charge controller type, depth of discharge, battery type, and desired charge time in peak sun hours. To charge a 100Ah lead-acid battery, you’ll need a 3-6 watt solar panel.
To fully charge a 100Ah 12V lithium battery using these 10 peak sun hours of sunlight, you would need a 108-watt solar panel. Practically, you would use a 100-watt solar panel, and in a little bit more than 2 days, you will have a full 100Ah 12V lithium battery.
Basically, the number of solar panels required to charge a 100 amp battery primarily relies on several factors, such as the power output of your solar panels and battery voltage. Indeed, you’ll need to consider the number of sunlight hours that your solar panels obtain.
