Nanosolar has had a history of technical and commercial promises, most recently these relating to cost:Below $1.00 per watt factory cost by the end of 2011
.
Low $0.80s or high $0.70s per watt by late 2012.
In the $0.60s in 2013.
Below $0.60 per watt in 2014Nanosolar produced 2.5 megawatts of panels in 2010. The firm has only shipped a cumulative total of 10 megawatts in its history.The firm has suggested that it will ship megawatts measuring in the "triple digits" in 2012. Cell production capacity was to be 115 megawatts at the end of 2011, and the next step jumps the firm to 250 megawatts of cell capacity at the San Jose facility. Panel assembly is performed at Nanosolar's factory in Luckenwalde, Germany.The firm is shipping 10-percent-efficiency panels today, with a target of 12 percent efficiency this year. Expectations are for 13 percent in 2013 and 14 percent in 2014. However, attaining a 4-percentage-point increase in efficiency in the space of four years would be an unprecedented feat never before achieved by any solar firm.
