Parallel Connection is usually used when all PV strings are located and oriented equally, have the same length and provide equal power output in the same period of time, in these cases all strings . [pdf]
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]

The MPPT operating voltage range for most string inverters is between 80V and 600V, depending on the inverter make and model..
The two most important values to collect are the maximum DC input voltage and the start or strike voltage of the inverter. 600 Vmax, 150 Vstart.
The inverter’s “maximum system voltage” sets the voltage limit for the maximum string length, typically either 1000 Vdc or 1500 Vdc for nonresidential inverters. [pdf]
