When wired in series, the 3 connected panels (often called a series "string") will have a voltage of 36 volts (12V + 12V + 12V) and a current of 8 amps..
When wired in series, the 3 connected panels (often called a series "string") will have a voltage of 36 volts (12V + 12V + 12V) and a current of 8 amps..
So you could have up to 19 panels in a string (rounding down to the nearest whole panel). String voltage = 37.6V * 19 panels = 714.4V.
The maximum number of solar panels you can connect in a string is determined by the maximum input voltage of your inverter or charge controller. You can find this value on the inverter datasheet. [pdf]
