Some key points about current for solar panels: Short Circuit Current (Isc): The maximum current your panel can produce in perfect conditions. Maximum Power Current (Imp): The current at your panel's most efficient operating point. You'll notice that solar panels are rated in watts. That's a very basic combination of the voltage and current.
The 100 Watts that this solar panel is capable of producing under standard conditions is, in fact, a product of the solar panel producing its Maximum Power Voltage (Vmp) AND its Maximum Power Current (Imp): Pmax (Watts) = Vmp (Volts) x Imp (Amps)
Voltage: Voltage is like the water pressure in a hose. It's the electrical force that makes electricity flow. Higher voltage means more “push.” Solar panels differ in voltage: Current: This is like the amount of water flowing through the hose. It's measured in amps (A). More amps mean more electricity flowing.
The current (in amperes, A) produced by the solar panel can be determined using Ohm's law, where the current is the power divided by the voltage: Current (A) = Power (W)/ Voltage (V) Given that our adjusted power output is 258W and the operating voltage of the panels is 36V, we can substitute these values into the formula to find the current:
