| aSystem costs could vary depending on climate, collector quality and type of system. Sources: Solar thermal costs are based on Energy Information Administration, Technology Forecast Updates: Residential and Commercial Building Technologies--Reference Case, prepared by Arthur D. Little, Inc. (Washington, DC, September 1998). PV costs are based on U.S. Department of Energy, Office of Building Technologies, Building Integrated Photovoltaics (BIPV), Analysis and U.S. Market Potential (Washington, DC, February 1995). Tax credits from Department of the Treasury, "General Explanations of the Administration's Revenue Proposals" (February 2000). Costs are given in 1998 real dollars. The tax credit is assumed to apply to the purchase price, including installation costs. | ||
