 See the //not enough panel// section below.

+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.

 Don't get me started on people **flat-mounting poly/mono flex panels to the roof of their van**.  Maximum cost, maximum power loss due to temp derating, //and// with the bonus of blasting re-radiated heat right through the van roof.  It's a crap trifecta.
-=== mixing different panels ===
-Mixing differently-rated panels will always be sub-optimal.  People  who know what they are doing can minimize the losses.  Beginners should either buy identical panels or run different types on separate controllers.
