+These averages are based on insolation and meteorological data for many years and are specific to that location.  Actual daily harvest will vary, so [[electrical:solar:overpaneling#vs_charge_controller|overpanel]] if you can and have sufficient battery bank capacity to [[electrical:autonomy|get you through temporary lulls in harvest]].
+====== DC-DC assumptions ======
+  * 50A DC-DC, which the alterator can power and batteries accept
+  * assuming average voltage of 13.0v for Amps-to-Watts conversion.
