But they figure out how to store solar energy in fuel cells, just recently.
Obviousely the oil or energy companies arn't going to invest in it,
becuase you won't need to be hook up to the grid anymore, day or night.

There's all kinds of connectors you can use or different ways you can go about it.
For mass production. Just go PCB, like your SD card..to keep the cost down.
Plus it'll be easier for the user and no pins to bend.
All you need are headers/plugs on the opposite side of the fingers.
They make those things up the waazoo. They even come in break away strips.
Molex, AMP, 3m, semtec...whatever your flavor..they all make it.

This way you can make thousands and thousand in a week becuase you
can just run a panel over a wave solider machine.
Each panel will have .. i dunno...50-ea sounds good.


For a garage job..I'd just use ribbon CBL and sometype of din connectors.
