Fred, the question to be addressed now is the cost of kapton. According to the latest press release from United Solar, the " 1-2 mil thick kapton substrate could result in a specific power density exceeding 2000 W/kg." This beats our current power density by four-to-one, as compared to our current "United Solar triple-junction modules that are made of amorphous silicon based thin-film alloys which are deposited on a 5 mil flexible stainless steel substrate. By utilizing a substrate which is between 0.5 and 1 mil thick, the new space cells have a specific power density greater than 500 watts per kilogram (W/kg), which is much higher than what is available." How might this impact our potential solar market and new proposed 25 MW plant? I guess it remains to be seen. Regards.
