Thin-film CIGS technologies are now entering the commercialization phase. We applied a unique technology using our established automotive mass-production know-how, and launched a commercial mass-production line at Honda Soltec Co.. Ltd. on October 2007. We achieved a nominal maximum output of 125 W and a module efficiency of 11.15% for a 1417 mm x 791 mm module. Honda CIGS photovoltaic systems were installed for inspection in more than 20 locations in Japan, USA and Thailand. Those in Japan (100kW in Shizuoka Prefecture) and Thailand (6kW in a suburb of Bangkok) are approximately 5 years old and have shown high reliability and durability. (C) 2009 Elsevier B.V.
