In February, First Solar tooted its horn about breaking the $1-per-watt barrier for making solar modules in the last months of 2008. This week, the company said costs had fallen again to 93 cents per watt, down 5% in three months and down 28% in a year. (The full presentation is here.)
First Solar executives also say to expect more falling costs. By 2014, it expects to drive down cost per watt to make solar modules to fall to between 52 and 63 cents by 2014. The biggest driver of the lower costs is better efficiency, it said. Production per fabrication line is expected to nearly double over the next five years.
