I remember that one, nice piece of work. The redstone timing must have been a pain.
Re the solar panel line, I didn't include glass or ingots as I have other lines producing those but they're easy enough to pipe in.
Attached some pics (excuse the layout, test rigs)
The ore factory takes Gold, Iron, Copper and Tin, splits them into lines and macerates them. Gold and Iron move to furnaces, copper and tin are split again, half to the craft bench in the forground to make bronze dust and half to furnaces. Everything then ends up in a trunk at the end.
Solar panel line looks messy but works well. Theres a couple of splits on the refined iron to account for the 1:4.5 ratio on machine blocks and circuits. Another loopback from the cable craft bench into the original trunk which them splits out to circuits and batteries.
Last pic is a real simple line for Carbon Plate from coal.
