A program of PV power generation systems in Japan was started as part of a national program called the "Sunshine Project" in 1974 and it continues today. The main objectives of technology development have been the cost reduction and mass production of solar cells, and system components. At present, solar cell manufacturing costs have been reduced to approximately 1/100 of the original cost, and Japan has become the global leader in both PV shipments and installed capacity. However, PV electricity generation costs are still too expensive to compete with the commercially provided electricity. Therefore, further efforts are required to create a full-scale market for PV systems as well as to elevate the status of PV power generation to an established energy supply technology. New Energy and Industrial Technology Development Organization (NEDO) has investigated various PV issues and developed long-term objectives to make PV energy a viable, long-term energy source. The result of these efforts was the establishment of "PV Roadmap Toward 2030 (PV2030)." NEDO has undertaken 2-year projects for preliminary research to make clear R&D direction and a process for achieving the targets by 2020.
