A 40-watt solar panel can charge any size 12v battery but it can only add 16 Amps to the battery bank in a whole day. 12v batteries come in different sizes so with the help of a charge controller you can store the DC power produced by the solar panels in the battery bank to later use Battery size for 40-watt solar panel?
The 40-watt solar panel can only add 16Ah to the battery bank, so if you're using a Lead-acid or AGM small 12v battery you'll need a 30Ah battery. But, I would recommend a 50Ah battery but for lithium-ion a 20Ah battery will be a best suit
A 40 watt solar panel can supply up to 40 watts an hour. This is the maximum output you can expect, but it could be lower than that depending on the weather. It will take a 40 watt solar panel 7 days to charge a 100ah 12 V battery. This is assuming the solar panel produces 200 watts / 3.3 amps a day.
600-watt solar panel will store 50 amps in a 12v battery per hour. Solar Panel Calculator For Battery: What Size Solar Panel Do I Need? How Long To Charge 12v Battery With Solar panel?
A 40 watt solar panel can charge a 12V 50ah battery in 3 days. A partially discharged battery can be recharged in even less time with 5 hours of sun available. How Long Does It Take a 40W Solar Panel to Charge a 12V Battery? To get the most accurate estimate, you have to account for the battery size and how many hours of sunlight are available.
Under ideal sunlight conditions, a 12v 40W solar panel will produce 18 volts, 2.2 amps, and 40-watt voltage output will depend on the intensity of the sun so which means it will fluctuate a lot so does the current. So you'll need a charge controller or regulator to manage the flow of voltage so you can charge your 12v battery.
