Now for the rest of the equipment. The following is a list of equipment and pricing to give you an idea of what things cost me. The prices were from May 2007. Below the list I will discuss DC and AC distribution

DC and AC distribution
To give you an idea of where to start here are a few pictures.

This is where my wire enters into the power station via 1" pvc for the solar panel feeds (left) and 2" pvc for the AC feeds (right). Make sure all ditches for conduit are at least 18 inches deep to pass North Carolina code.

This is where my wire enters my house via 2" pvc for the AC feeds (6 conductors). I did not have a 2" concrete hole saw so what I did was used a 1/4 " masonry bit in my hammer drill. I traced the 2" hole onto the concrete with a marker and drilled a bunch of holes around the 2" circle mark. Once I drilled enough holes I just knocked the concrete out with a hammer. Took about 10 minutes.

Below is a picture from inside the power station. You can see where the solar and AC feeds (via pvc conduit) enter the building and go into metal boxes.
The 1" conduit goes into a 4" square metal box with a ring extension (screws on to the front of box to make it deeper to accomodate wires - should have used a larger box but it was all I had at the time). The 2" conduit goes into a 10"x 10" x 6" deep metal "can/box. This metal can was bought at fox electric supply. They have good deals there.
