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. .
By knowing how much power can a 40w solar panel produce will let you know the actual worth of your solar panel and also this will determine what you can run on your. .
So you'll need a charge controller or regulator to manage the flow of voltage so you can charge your 12v battery. To calculate the size of the charge controller or regulator for your solar panel use this formula you'll need a 5A charge controller with a 40W solar panelbut I would recommend a 10A charge controller which will give you a room. .
in short, 40W solar panel can run a small DC fan, charge a cellphone, 22 Inch LED TV, Air Purifier, Aquarium Pump, DVD Player, Extractor Fan, LED lights, etc. There are a few key points to keep in mind 1. The total power produced by the solar panels (Per hour & per day) 2. AC vs DC load 3. The size of the battery bank As we know, the. [pdf]
