Solid conductors are not generally accepted for use with DC currents. Well at least not in the currents I'm use to dealing with. DC currents don't travel over long distances very well. And stranded conductors are better suited to help transmit those currents.

If the OP is using a #12 ( or even a #10 ) conductor to carry a 40 Amp load, then he has exceeded the capabilities of those conductors ( solid or stranded ).
