 **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.

-**Overpaneling**, or having "too much" panel for the rating of your MPPT charge controller, can be desirable in some situations.  It is a **trade-off that biases the setup** to get more power out of normal and marginal conditions at the expense of the peak output during optimal conditions.((sun overhead, clear sky, low temps))

 >In car terms, the overpaneled system trades away some of the panels' top-end output for more low- and mid-range grunt. -- secessus
