Shares of First Solar ( FSLR) were rising Tuesday despite news that a new competitor has emerged.

Start-up Abound Solar, based in Fort Collins, Colo., began producing panels using cadmium telluride, as does Tempe, Ariz.-based First Solar.

We think we have a slight technological advantage over First Solar," CEO Pascal Noronha told Reuters in an interview. "We have a manufacturing process that is about as continuous as making beer cans, and therefore makes us the lowest cost manufacturer of photovoltaic modules."
