 Solar panels, also called photovoltaic (PV) panels, produce DC power from sunlight to charge batteries and provide electrical power. ​ The panels can be used single or in [[electrical:​solar:​series vs parallel|series or parallel]] arrays. Solar panels, also called photovoltaic (PV) panels, produce DC power from sunlight to charge batteries and provide electrical power. ​ The panels can be used single or in [[electrical:​solar:​series vs parallel|series or parallel]] arrays.
  
-Since PV necessarily run at higher voltages than the batteries they charge, a [[electrical:​solar:​charge controller|charge controller]] is placed between the PV and the battery bank.+To avoid overcharging,((a bit of an oversimplification,​ admittedly)) ​a [[electrical:​solar:​charge controller|charge controller]] is placed between the PV and the battery bank.
  
 [[electrical:​solar:​output|Many factors]] will affect output; and panels will rarely generate power equal to their laboratory rating. [[electrical:​solar:​output|Many factors]] will affect output; and panels will rarely generate power equal to their laboratory rating.
