Breakeven Cost for Residential Photovoltaics in the United States: Key Drivers and Sensitivities (Report Summary)
"Break-even cost" for photovoltaic (PV) technology is defined as the point where the cost of PV-generated electricity equals the cost of electricity purchased from the grid. Break-even cost is expressed in $/W of an installed system. Achieving break-even cost is a function of many variables. Consequently, break-even costs vary by location and time for a country, such as the United States, with a diverse set of resources, electricity prices, and other variables. In this presentation, we introduce an analysis of PV break-even costs for residential customers in the United States, including an evaluation of some of the key drivers of PV breakeven both regionally and over time. This presentation includes our methodology and presents results for both near-term residential breakeven costs(2009) and future market sensitivities of break-even costs (2015). See also the the report "Break-Even Cost for Residential Photovoltaics in the United States: Key Drivers and Sensitivities". Presentation for NREL/TP-6A2-45991.
