TLDR; series operation shouldn't be a problem unless you're trying to wring every last bit of performance from the devices.

My father-in-law was a truck driver and I got ahold of a tec unit from his cooler/warmer that the temp switch went bad in. I've built a couple for on the go power from some teg cells I got from a company in W.V. I have a vegetable oil stove that I use to heat one that is 14v at 2 amps. The first picture is from a kerosene powered fan I made from a trucker cooler. I have demonstrated it for 14 years at engine shows and sustainable energy shows. The second is a 14v at 1amp at 250f delta t. I use it for camping on the Coleman stove with a pot of water on top for cooling. The tec's we made a chicken water cooler and heater depending witch side you flip up. It takes 60 watts to fully power it, but works good for me with a 50w panel.

My first couple I let the smoke out. We also use the supper caps to store and buffer. Have any of you played with a joule thief circuit to jump voltage? I have been stealing the parts out of blown florescent curly type bulbs. They work, some better than others. I use them to jump the voltage from a tec from 1V to 2v, then I can charge batteries or caps with them.
