1. Does This Shape Motivate Us To Install More Solar PV? Ken Zweibel Executive Director, GW Solar Institute The George Washington University [email_address] http:// solar.gwu.edu / http:// thesolarreview.org /

6. $3/W large, fixed flat-plate PV system in US Southwest sunlight (a third better than US average). Includes 0.5% replacement per year (at 75% of today’s high prices) to offset expected system degradation (a conservative assumption since not everything will be replaced and efficiency will improve and costs drop). End of Loan Repayment Operating costs only
