 The details of Bill's logic and math has been [[electrical:solar:daily-gentle|moved to its own page]], but for now we will stipulate he came up with a daily requirement of **91Ah** of usable battery capacity for each 24hr period.  On average he will consume that much power each day, and will have to replace that amount((and a little bit more due to charging inefficiencies)) from the sun. The details of Bill's logic and math has been [[electrical:solar:daily-gentle|moved to its own page]], but for now we will stipulate he came up with a daily requirement of **91Ah** of usable battery capacity for each 24hr period.  On average he will consume that much power each day, and will have to replace that amount((and a little bit more due to charging inefficiencies)) from the sun.
  
-**A peak ahead:** for reasons that will be explained later, this requirement means he will need about 200Ah of lead battery (flooded or AGM)((or 100Ah of lithium)), and 200w+ of solar panel, depending on [[opinion:frater_secessus:panelsizesforinsolation|where the camper will be used]]. +**A peek ahead:** for reasons that will be explained later, this requirement means he will need about 200Ah of lead battery (flooded or AGM)((or 100Ah of lithium)), and 200w+ of solar panel, depending on [[opinion:frater_secessus:panelsizesforinsolation|where the camper will be used]].

-200W is not a magic number, but it is the most common size of solar install for vandwellers and [[camping:dispersed|boondockers]].  It is probably more than what's needed for the basics and has enough power to add in a [[food:refrigeration#compressor_refrigeration|12v compressor refrigerator]] if desired.((assuming good conditions like the desert southwest))  When [[electrical:12v:alt_and_solar|combined]] with an [[electrical:12v:alternator|isolator]], 200W is probably all the average camper needs in typical conditions.+200W is not a magic number, but it is the most common size of solar install for vandwellers and [[camping:dispersed|boondockers]].  It is probably more than what's needed for the basics and has enough power to add in a [[food:refrigeration#compressor_refrigeration|12v compressor refrigerator]] if desired.((assuming good conditions like the desert southwest))  When [[electrical:12v:alt_and_solar|combined]] with an [[electrical:12v:alternator|isolator]], 200W is probably all the average //camper// needs in typical conditions.  Folks that want to run microwaves or other power-hogging appliances will have to pony up with more gear and more $$$. 
  
 Going beyond the basics, handling the basics more frugally, or running non-trivial loads off an inverter will require more research, planning and patience.  Read on, and follow links in the text to drill down to deeper explanations.  Beware that some of the links are technical. Going beyond the basics, handling the basics more frugally, or running non-trivial loads off an inverter will require more research, planning and patience.  Read on, and follow links in the text to drill down to deeper explanations.  Beware that some of the links are technical.
