This application generates predictable savings that support project economics. Behind-the-meter solar integration enables C&I customers to maximize self-consumption of on-site generation. Storage captures excess solar production for use during evening hours or cloudy periods, reducing grid purchases and enhancing the economics of solar investments. Backup power capabilities provide additional value, particularly in regions with grid reliability challenges. Storage systems can maintain critical loads during outages, avoiding business interruption costs that often exceed electricity savings. Residential Storage Residential storage continues to expand, driven by retail electricity rates, solar integration, and energy independence motivations. The residential segment exhibits distinct characteristics including smaller system sizes, emphasis on aesthetics, and simplified installation requirements. Solar self-consumption remains the primary application for residential storage in most markets. As net metering policies evolve, the economic case for storing rather than exporting solar generation strengthens. This trend is particularly pronounced in markets with high retail rates and unfavorable export compensation. Backup capability drives adoption in regions with grid reliability concerns. Residential customers increasingly view storage as insurance against outages, with the economic value of avoided outages justifying system investment in some cases.
