The stand-alone PV system (a) uses battery storage to provide dependable DC electricity day and night. Even for a home connected to the utility grid (b), PV can produce electricity (converted to AC by a power conditioner) during the day. The extra electricity can then be sold to the utility during the day, and the utility can in turn provide electricity at night or during poor weather In addition to the solar cells and modules, a small solar electric system (or photovoltaic system) consists of other parts called balance-of-system components. The balance-of-system equipment required depends which of the following systems is being used: Grid-connected Stand-alone Hybrid A typical small solar electric system usually includes the following balance-of-system components: Mounting racks and hardware for the panels Wiring for electrical connections Power conditioning equipment, such as an inverter Batteries for electricity storage (optional) Stand-by gasoline electric generator Related category    • SOLAR ENERGY AND POWER Source: US Department of Energy Also on this site: Encyclopedia of Science Transport Concepts & Designs (partner site) BACK TO TOP
