As of publishing, the average cost per watt is $2.84. Most solar companies set the price according to the solar system''s wattage. A solar installation''s “cost per watt” is a little like the “price per square foot” when you buy a house. It helps compare the value of solar energy systems in different sizes.
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 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?
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.
