-The bare-bones minimum for solar, assuming everything goes exactly right,((shallow discharge, excellent solar conditions, well-designed system))  is [[electrical:solar:panel-bank_ratio|1:1]] panel-to-Ah.  e.g. 150w for a 150Ah battery bank.  In reality, solar that small is often insufficient unless one has unusually small power needs or adds in another form of charging (see below).  [[opinion:frater_secessus:beginner_mistakes|Newbies typically think their power needs are small]] until they sit down to read those power labels on the stuff that want to run.  D'oh!  +The absolute minimum for solar, assuming everything goes exactly right,((shallow discharge, excellent solar conditions, well-designed system))  is often said to be [[electrical:solar:panel-bank_ratio|1:1]] panel-to-Ah.  e.g. 150w for a 150Ah battery bank.  In reality, solar that small is often insufficient unless one has unusually small power needs or adds in another form of charging (see below).  [[opinion:frater_secessus:beginner_mistakes|Newbies typically think their power needs are small]] until they sit down to read those power labels on the stuff that want to run.  D'oh!

-This isn't a game or vacation anymore;  //this is your life//. You need power every day and under all conditions.  The most reliable way to do this is by [[electrical:solar:overpaneling|overpaneling]] (having massive solar to account for all weather conditions), although you could do it with smaller solar [[electrical:12v:alt_and_solar|combined with]] a [[electrical:generator|generator]]. +FT boondocking game or vacation anymore;  //this is your life//.

 Battery banks tend to be either lithium or flooded 6v golf cart((CG2)) batteries in series, both of which have lifetime $/kAh costs under $2.   Battery banks tend to be either lithium or flooded 6v golf cart((CG2)) batteries in series, both of which have lifetime $/kAh costs under $2.
