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
