The Sandia Laboratories' optimizing computer code, SOLSTOR, has been used to investigate the role of battery storage in a residential photovoltaic system. The system is connected to the utility grid, and Time-of-Day (TOD) pricing and sell-back policies are considered. Several parameters, including geographic location, were varied, resulting in a large number of systems optimized with respect to the 20-year life cycle cost of providing energy for an all-electric home. Conclusions are that battery costs of around $100/kWh or less are required for storage to be economically beneficial, when combined with TOD ratios of 3:1 or more, or sell-back ratios of 0.5 or less.
