+Posts that include "my needs are simple, all I need are lights and a fan" develop, after questioning, into "Yeah, forgot the laptop.  And phone.  And tablet.  And toaster.  And coffee maker."  It's like [[https://youtu.be/2ZTdqh-a0tU?t=120|the scene from that Steve Martin movie]] where all he needs is an ashtry, then collects more and more stuff as he walks away.

+==== believing 100w of panel will make 100w all year ====
+Solar harvest is greatly affected by the position of the sun in the sky (see above) and how many hours of that sun are available.  A crude generalization is that [[https://mouse.mousetrap.net/blog/2021-12-12-Summer-vs-Winter-solar-harvest-.html|winter harvest will be about half]] of summer harvest.
+==== believing 100w of panel will make 100w in all conditions ====
+w of panel makes 100w under lab (ie, perfect) conditions.  [[electrical:solar:output|Actual harvest]] will be much lower on average.
 ==== believing solar makes zero watts in rain, overcast, etc ====
