For a 6W panel at 6V, the current will be: Current (A)=Power (W)/Voltage (V)=6W/6V=1A In this case, the solar cable needs to be able to handle at least 1 amp of current. Current is calculated by dividing the power of the panel (in watts) by the voltage (in volts). This showcases that these panels are efficient for small-scale energy. . This is your typical voltage we put on solar panels; ranging from 12V, 20V, 24V, and 32V solar panels. This is the maximum rated voltage under direct sunlight if the circuit is open (no current running through the wires). (example, 2AC amps =20DC amp) Add 10% (22 amps) DC amps x 12v = DC watts. (22 x12 =264 watts) 264 would be entered in field # 3 Fields #6 and #12 are for how many hours you expect your equipment to run in a 24 hour period, and your. .
