This paper examines the effects of large-scale penetration of solar PV in Japan. Since the government adopted in 2009 the feed-in tariff on renewable energy sources, the solar PV has been popular for both for residential and non-residential users. This paper employs power system simulation and assess several scenarios on the penetration of solar PV in 2020. The paper finds two major results; (1) the penetration is reached at 4000GW, the annual peak demand would shift from summer to winter. No kW value would be placed on an additional unit of solar PV. (2) Since solar PV would replace thermal power generation, the fuel cost of the generation would reduce with penetration of solar PV, but at a slower rate.
