The maximum number of modules in series can be as much as 11..
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.
You want to have an equal number of panels on each string, so let's bump it up to 16! So, 16 panels/2 strings = 8 panels in series per string..
