摘 要：he U.S. Department of Energy's (DOE) SunShot Vision Study (DOE 2012) explored the impact of reducing solar prices by about 75% from 2010 to 2020 on the potential deployment of solar technologies in the United States. DOE's SunShot Initiative envisions reaching a $1.50/W installed system price for residential rooftop photovoltaic (PV) systems by 2020 and a $1.25/W installed price for commercial rooftop PV systems by 2020. The SolarDS model was used to simulate rooftop PV market demand based on these price projections, along with several market assumptions, including customer access to financing, future retail electricity rates, and net-metering policies. In the SunShot Vision Study, U.S. rooftop PV demand increased from about 1 GW in 2010 to 121 GW by 2030 and 240 GW by 2050.
