How Series Vs Parallel Wired Solar Panels Affects Amps & Volts
This means there are 20 Amps at 20 Volts coming into the solar charge controller. The above diagram shows five, 9 amp, 18-volt panels wired in parallel. Since parallel wired solar panels get their amps added while their volts stay the same, we add 9A + 9A + 9A + 9A + 9A to show the total array amps of 45 Amps while the Volts remain at 18 Volts.
