     * higher PV voltage can run in relatively **thinner wires** to the charge controller     * higher PV voltage can run in relatively **thinner wires** to the charge controller
     * serial connections can provide **some charging in low light situations** where lower voltage parallel or single-panel connections might not.  Imagine two nominal 12v panels running at 11v at sunrise;   the series arrangement might yield ~22v (battery charging) instead of 11v (voltage too low to charge battery).  Note that power harvestable at those times may be quite low.      * serial connections can provide **some charging in low light situations** where lower voltage parallel or single-panel connections might not.  Imagine two nominal 12v panels running at 11v at sunrise;   the series arrangement might yield ~22v (battery charging) instead of 11v (voltage too low to charge battery).  Note that power harvestable at those times may be quite low. 
-    * higher-voltage serial configurations with MPPT controllers may provide [[electrical:solar:shading#exceptionhigh_voltage_strings_mppt|more power under partial shading]] +    * higher-voltage serial configurations with MPPT controllers may provide [[electrical:solar:shading#exceptionhigh_voltage_strings_mppt|more power than parallel under partial shading]]. This is highly controller-dependent. 
     * higher voltages **work well with MPPT controllers**     * higher voltages **work well with MPPT controllers**
     * higher voltages can **charge higher voltage battery systems** like 24v.     * higher voltages can **charge higher voltage battery systems** like 24v.
