To calculate the current when your solar panel is generating its maximum power, you need to divide the maximum rated power of the panel in watts by the maximum power voltage (Vmp) which is also in volts. You can find the wattage of your panel on the back of it, or in. . We usually measure or convert the watts into amps of solar panels to figure out how much current (amps) is being stored in the battery. So if your goal is to figure out how many. . Converting watts (W) to amps (A) tells you how much electrical current flows through your system for a given power output. Typically, an 18v panel can deliver between 5 to 7 amps under optimal conditions. The amount of electricity the panel produces depends on the size of the panel, the intensity of the sunlight, and the circuit it's connected to. These estimations can be derived. .
