Are you doing any photography with the scope?
Once you have set the latitude angle with an inclinometer and yes Solar North is a good way of getting your North South line.
If you can fit a colour camera then set up and take a 30 or 60 second shot at a high ISO say 3200 and then study the image and look for the three central stars that you see in the charts previously posted, one is quite bright and red.
If you can see those in the image then you're not far off and you can make your adjustments from there.

Good luck with it.

I've added a screen shot from TheSky6 and this is roughly what you should see if aligned with an 8" SCT.
The red star and the two brighter stars below are what to look for in the picture, take a wide field if you can, and the red star and the two faint ones down to the left point right at the pole. You can also see them through an eye piece given that you don't have a lot of light polution, you won't see all the faint ones but the three main stars are quite visible.
