Stand-alone systems are independent from the utility grid, avoiding the possibility of losing power when the grid goes down. Electricity from stand-alone systems are used on site, such as an RV or cabin. Power that is generated can be stored in batteries and used at night or on sunless days. A generator may also be used for back-up. For PV applications, the size of a stand-alone system is usually up to 50kW.
