To calculate the value of amps or current use this formula (Amps = Watt/Volts) 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.
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).
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.
A solar panel wattage calculator can help optimize your solar power system for maximum efficiency and cost-effectiveness. This calculator considers variables such as panel efficiency, sunlight intensity, and environmental conditions, allowing for a more accurate prediction of the electricity a solar panel can generate.
