TechSurveillance Solar Leasing and Solar PPA Programs: The Increase in Residential Photovoltaic Solar Deployment NOVEMBER 2013 This article explores the basic business model and solar leasing program offered by SolarCity*—the largest, vertically-integrated, and only publicly traded solar leasing company at this time. It will compare leasing programs to the traditional method of purchasing a solar system outright, describe how SolarCity makes money, and break down the elements driving profits, such as high retail power rates, declining costs, tax credits, and net metering rules. Finally, this article will make a few suggestions to electric cooperatives on how to deal with the threat of loss of kWh sales and possible advantages of third-party partnerships. INTRODUCTION The solar industry has benefited for years from state and utility incentives, federal investment tax credit (ITC), accelerated depreciation, and generous net metering laws. In the latest quarterly report published by GTM Research and the Solar Energy Industries Association (www.seia.org/research-resources/us-solar-market-insight-q1-2013), PV solar installations totaled 723 MW in Q1 2013, up 33 percent over Q1 2012, giving the U.S. a PV solar operating capacity of 7,962 MW—a 60 percent increase from two years ago. Despite the likelihood that these incentives will be less valuable over the coming years, GTM/SEIA forecast a strong 30 percent annual growth rate in solar installations through 2016 (see Figure 1). * There are a number of companies offering solar leasing across the United States, including Citizenre, BrightGrid, Sun Run, Vivint, SunEdison, and SunPower. Each company’s offerings vary based on geographic operations, target consumers, length of lease, and business model. NRECA does not have a position on any particular solar leasing company. This article was written to provide NRECA member co-ops with the best information available at this time to support technology business decisions. nreca members only Solar Leasing and Solar PPA Programs: The Increase in Residential Photovoltaic Solar Deployment | 2 10,000 9,186 9,000 8,000 7,045 7,000 6,000 5,306 5,000 4,375 4,000 3,328 3,000 Installed Capacity (MW dc) (MW Capacity Installed 2,000 1,890 1,000 848 0 2010 2011 2012 2013E 2014E 2015E 2016E Source: GTM Research and the Solar Energy Industries Association (U.S. Solar Market Insight: Q1 2013) FIGURE 1: U.S. PV Installation Forecast, 2010–2016E The government incentives are not the whole Although customers can buy a SolarCity solar story for why solar is booming.
