2008太阳能产业预测：美国太阳能市场前景轨迹--robinyan.ppt

* * * * * * Assumptions: For the price of electricity, the average electricity price for the 1000 largest utilities in the U.S. based on EIA data for 2006 (except CA, where existing tiered rates structures were used). A 6% price derate factor was assumed to remove fixed billing charges. TOU rates included (+20% price adjustment) for select states in 2007, and all states in 2015. Electricity price escalated at 1.5% per year in moderate case and at 2.5% per year in more aggressive case. The solar performance is based on NSRDB weather station closest to the center of the utility service territory, assuming a south facing array, at 25 deg tilt. An 82% derate factor is used to account for inverter and other PV system loses, but no performance degradation over life of the PV system is assumed. For the financial analysis, the installed system price is set at $8.5/Wp in the current case and $3.3/Wp in 2015. The system is assumed to be financed with a home equity loan or through mortgage (i.e., interest is tax deductible), with a 10% down payment, 6% interest rate, with the owner in the 28% tax bracket, and a 30 year loan/30 year evaluation period. Incentives included are the Federal ITC worth $500/kW due to $2000 cap and individual state incentives as of December 2007 in the current case and no Federal ITC or state incentives in 2015. * 13% real increase in price of electricity. In this case, solar PV is very attractive in states in the Southwest, largely due to good solar resource and high electricity prices, especially in California. PV is also very attractive in the Northeast, due to high electricity prices. * 22% real increase in price of electricity. Potential factors influencing future electricity prices: emerging climate regulations, other environmental issues, transmission constraints, the rising cost of key commodities used in the construction of traditional power plants, and rising fossil fuel prices. In this case, PV is at “breakeven” in a much larger area o
