     * 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 in heavy cover:((due to MPPT's response to shading))  the series arrangement might yield ~22v (battery charging) instead of 11v (voltage too low to charge battery).  Note that power harvestable at those times is so low as to be of little practical use.

     * higher voltages **work well with MPPT controllers**
     * higher voltages can **charge higher voltage battery systems** like 24v.
