The company, which is developing a solar technology using copper-indium-gallium-diselenide instead of silicon, last year closed a $75 million Series-C round of funding and said the money, combined with government subsidies, would add up to $100 million.
Nanosolar said it was building a 430-megawatt plant in San Jose, expected to be completed this year, and another factory, which would assemble more than 1 million solar panels annually, near Berlin.
CEO Martin Roscheisen confirmed Tuesday that preparatory work has begun on the German site. The Luckenwalde facility, expected to begin making panels in the first quarter of next year, will be able to make "multi-100" megawatts of solar panels annually once it's fully ramped up, he said.
