Here is a simple solution to align and fixate cells while tabbing solar cells together. This is very good because I can focus on soldering cells instead how they are aligned and fixed. People also use tape to fixate and long ruler or something similar to align them beforehand. This is different solution. Maybe it gives someone idea for tabbing. It’s actually not a new idea- I have found that people have used this idea before. First link I found was on instructables.
Here I use 2.5mm (~0.09 inches) tile spacers which can be found in your local hardware store at low price. Super glue and a piece of scrap plywood for base. I just glued crosses on plywood – seems to hold good enough. And it’s done.
I have little loose spacing so cells won’t be too tightly inside corners. It prevents damaging cells when removing them from jig.

My first solar cell arrays came out good. No drawbacks nor problems rise up at moment. The whole project building my first (OK- actually it was second panel I built) solar panel also succeeded at least in aligning part. Maybe one day I’ll share this project. When sun comes out and I can get some real data.
