I did not make my own solar CELLS. I bought cells and made them into panels.

What I thought would be a 100 watt panel puts about 2.5A into a battery at 25V. So more like 60W. I think I'd do better with 38 or 40 cell strings as my VOC seems a little low.

I bought these cells super cheap. Probably have less than $500 into 250W of solar. Unless you can get your cells for about $1/watt I do not think an enterprise such as I have undertaken would be financially viable.
