THE PRESENT STATUS AND FUTURE DIRECTION OF TECHNOLOGY DEVELOPMENT FOR PHOTOVOLTAIC POWER GENERATION IN JAPAN

摘要

NEDO last year established the "PV Roadmap toward 2030 (PV2030)" as a long-term strategy for PV R&D. In this Roadmap, PV is expected by 2030 to supply approximately 50% of residential electricity consumption (cumulative installed capacity in the rang of 100GW). In terms of economic efficiency, electricity costs are targeted to equal commercial use, approximately 14 Yen/kWh, by 2020 and industrial use, approximately 7 Yen/kWh, by 2030. For future PV systems, it is essential to improve the stand-along capabilities of PV system with electricity storage and to develop community-based PV systems using multi-function inverters. Advanced technological innovations beyond the existing levels are also essential. Therefore, NEDO is undertaking 2-year projects for preliminary research to make clear the nest R&D of solar cells and PV system technology.
