subject: Voltage Characteristics and Solar Panels - Why So Many and What Do They Mean? [print this page] *Nominal voltages for solar panels that can't be found in batteries, such as 18V, are increasingly common. These voltages are based on PV modules that were not designed specifically for battery-charging systems, such as those used in straight grid-tied PV systems. These voltage solar panels can be used with lower voltage battery banks, but require a Maximum Power Point Tracking (MPPT) type of solar charge controller to efficient down convert the DC voltage.
