 In practical terms, it's common to see a maximum of 75% of STC under good conditions, more under great conditions, and much less under poor solar conditions. And about half of that in winter.
+===== where and when =====
+The location and season both have profound effects on solar harvest. [[opinion:frater_secessus:panelsizesforinsolation#representative_areas|For example]], Phoenix AZ has **over 8.5x the amount of solar power** available in summer as Seattle WA in the winter.  For any given location, winter harvest will be about half of summer harvest.
+You can estimate solar harvest using [[electrical:solar:pvwatts|models like PVwatts]].
 ===== lack of demand =====

 Pro:
-  * +30% daily harvest is possible, depending on the sun's position((peak harvest may be much higher at some times but daily harvest is more applicable for offgrid vanlife))
+  * optimal tilt will increase harvest when the sun is low and skies are clear.((peak harvest numbers are more impressive but of less import.))
-  * can be used to increase harvest if roof space is maxxed (cannot add more panel)
+  * can be used to further increase harvest if roof space is maxxed (cannot add more panel)
