 The overpaneled system's power output bell curve is //shifted upwards// and cut off by the controller when it reaches its limits.  This is known as clipping, trimming, or clamping due to the "flat top" appearance of the overpaneled output curve. The overpaneled system's power output bell curve is //shifted upwards// and cut off by the controller when it reaches its limits.  This is known as clipping, trimming, or clamping due to the "flat top" appearance of the overpaneled output curve.
  
-With modest overpaneling the clipping is relatively minor.  Victron notes that:+With appropriate overpaneling the clipping is relatively minor.  Victron notes that:

 Since the underbanked system has less capacity will reduce your actual [[electrical:solar:sizing#your_reserve_needs|reserve days of power]] to some extent.  But during daytime there is //some// solar power coming in and an overpaneled configuration will harvest relatively more power in sub-optimal conditions.  The smaller bank will get through Bulk and well into Absorption faster, too. This will help extend the //effective// reserve days of power. Since the underbanked system has less capacity will reduce your actual [[electrical:solar:sizing#your_reserve_needs|reserve days of power]] to some extent.  But during daytime there is //some// solar power coming in and an overpaneled configuration will harvest relatively more power in sub-optimal conditions.  The smaller bank will get through Bulk and well into Absorption faster, too.
