-**Example:**  Consider the image to the right.((The image is that of a different PV-related configuration but it works for our purposes.)) The smaller/interior bell curve is the normally paneled configuration. \\

 The larger/exterior curve is the overpaneled configuration. \\
 The striped area is the peak power "clipped" by the controller when the controller is overpaneled.  \\

   * you spend time in partial shade
   * you want to use a smaller controller instead of jumping up to the next size.  Example, 43A max output and your choices are 40A or 60A controllers.
+==== example ====
+Let's say you want to adhere to Victron's 10-30% overpaneling approach.  Working backwards, their model appears to use 14.2v Vbatt as a constant.
+  * 500w / 14.2v = 35.2A.
+  * 35.2A on a 30A MPPT is    17.3% overpaneled:  ( (35.2 - 30) / 30 = 0.173)
