 Having no solar at all is generally an unforced error for vandwellers.  Even [[electrical:12v:alt_and_solar|adding small amounts of panel]] (100w) can make a big difference, and can be added to an [[electrical:12v:alternator|alternator-charged system]] for as little as $100.((100w poly panel on sale for $90, 10A [[electrical:solar:shunt_tweaking|shunt controller]] for $10.))

+Shade will wreck solar harvest.  Beginners often don't pay attention to shade conditions, including shade thrown by objects on the van roof itself.

 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.
