It won't! That's the amazing thing about electricity.
While having 12kV going through panels is not safe for many reasons, having 300V at 10-20A is completely normal.
12kV is impractical because these voltages can jump quite far, and you need a lot of insulation for them to be safe.
And so ultimately, despite my details being wrong about currents, the notion of stringing miles of panels together is probably not a good basis for rejecting the panels over the canals.
