Well, I pulled it off. I separated the 0.5V solar cells in to two groups. Each group was wired in series and consisted of 3 rows of 9 cells each. The two groups were then wired in parallel. I did this so that if one cell or section went out, enough voltage would still be produced to charge the 12V deep cell battery.

After soldering the cells together in the rows, I attached them to a thick plywood board that I had previously covered with a white, UV-protectant paint. Once the cells were attached using a dollop of silicone in only their centers to account for expansion and contraction of both the board and cells in various weather environments, the rows from each section were then connected in series by soldering tabbing wire. Both sections were then connected in parallel with the same copper wire that one would find in a solar output cable and a blocking diode was added to the positive wire inside the solar panel to prevent the backward flow of power at night or in less than ideal sun conditions.

Everything from the solder joints to loose wiring withing the panel was stuck to the board with silicone. I cleaned off the solar cells themselves with glass cleaner. A thin wood frame was placed around the edges of the board upon which I attached a 1/8" thick piece of plexiglass which seems fairly durable and recently survived a hail storm. The frame also has a few small holes drilled in the bottom to equalize the air pressure inside the panel and allow for condensation to run out should it ever gather in there. The outside of the panel where the wood and plexiglass connect were coated with silicone to prevent water from getting in.

A test with the multimeter showed me that power was indeed flowing so I connected the positive and negative wires that I had left hanging out through a hole in the bottom of the panel to the solar output cable.

I meant that I'm concerned about one of them going out if wired in series and losing the power from the cells behind it. I also meant to say that the videos I've seen wired them in series, but due to my concerns I would like to wire them in parallel. Sorry about the mistyping.
