Residential customer-sited photovoltaics markets 1999

Nearly three years ago, the authors published the paper, Niche Markets for Grid Connected Photovoltaics. The paper identified target market niches for Customer-Sited Photovoltaics (CSPV), on a state-by-state basis for the US. The paper demonstrated cost-effective, grid-connected, domestic markets existed and identified those showing the most near-term promise. Many financial and policy attributes effecting the economics of CSPV have changed since the previous paper was published. Incorporating these policy changes into the analysis expands the CSPV market from a niche status to an era of significance. The number of states with break-even turnkey costs (BTC) above four dollars per watt expanded from five to fifteen. The top five state market values are now above a break-even cost of seven dollars per watt, a value at which the domestic CSPV market moves beyond a break-even status to consumer savings or industry profit, depending on system price. Emissions mitigation values were also included in the paper, but did not significantly effect the break-even market value results. The paper presents the details of the data, analysis, and results
