This text presents results from the first US Department of Energy (DOE) sponsored, bottom-up data-collection and analysis of non-hardware balance-of-system costs - often referred to as business process or soft costs - for residential and commercial photovoltaic (PV) systems. It quantifies the indirect corporate costs required to install distributed PV systems as well as the transactional costs associated with arranging third-party financing. It accompanies the recent 'National Renewable Energy Laboratory' soft cost benchmarking report (2013), which quantifies all the non-hardware balance-of-system costs associated with building a residential or commercial PV system.
