I'm no pro, but I think if you check the Kethane items in the vehicle assembly building it will tell you the power consumption. If you look at your power supply sources it will tell you what power it can produce. From there it should be fairly simple math. A large drill has a power consumption of 24.00/s and a single large solar array provides 18.00/s power. I've only done simple builds so far and have to wait until daylight for my 6 large panel array before I can mine and process kethane.
