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?
During this conversion, there will be some power loss of about 15-5% (depending on the inverter efficiency rate) so most of the inverters are about 85-90% efficient So if you're running an AC load directly from your 40W solar panel then your output load should not exceed 27 watts (32*0.85 = 27 Watts).
A 24V solar panel can charge 120 watts to a 12V battery. If you charge a 24V solar panel to a 12V battery, it will charge at 8.3 amps and draw the voltage down to what the battery can handle. Only 120 watts of the possible 300 watts from a 24V solar panel are charged to a 12V battery because of the low voltage.
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
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.
