 **Note:**  overpaneling is not //overvolting//, which would be exceeding the maximum input voltage of the charge controller.  Overvolting often results in damage to the controller; it can be caused by linking too many panels in series, or running too close to the voltage max in conditions that raise the panels' Voc.((http://www.cheaprvliving.com/forums/Thread-36-volt-solar-panel?pid=144154#pid144154))
 ===== vs. charge controller =====
+**TL;DR**:  overpaneling the controller means sizing MPPT for //actual// incoming solar power rather than //rated// panel wattage.
