Velleman Encapsulated Solar Cell (1V/200mA)
What is the physical size of this item and how many of them must i get to provide: 5.1 volts 2.1 amps 12 watts
I've got very basic knowledge of power, but watts = amps x volts. If you hook up power in series, you add together the voltage but not amperage. If you hook them up in parallel, you add the amperage but not the volts. Knowing that, you'll need a combination of series and parallel submodules. To get to 5v you'll need to hook 5x of these in series, which will give you 5v 100mA. To get your 2.1 amps, you'll need at least 11 sets of those 5x modules, or 55 cells total. You'd hook the 11 sets of 5 together in parallel, which will give you 5v at 2.2 amps. This will give you 11 watts of power. To get 12 watts, you'll need to add a 12th set of 5x cells, so to get what you want, you'll need 60 of these total. In the end you should have 5v 12W 2.4 amps. Someone with more experience please correct me if I am wrong! :)
