 Sizing **residential off-grid solar configurations** is relatively easy: calculate power needs in the worst case scenario (December in a particular geographical area)((https://web.archive.org/web/20110906013732/http://www.solarpowerforum.net/forumVB/solar-energy/1793-basic-off-grid-solar-design.html)) and pay for it.  Sizing **residential off-grid solar configurations** is relatively easy: calculate power needs in the worst case scenario (December in a particular geographical area)((https://web.archive.org/web/20110906013732/http://www.solarpowerforum.net/forumVB/solar-energy/1793-basic-off-grid-solar-design.html)) and pay for it. 
  
-  - worst case scenario loads (the max loads you will apply in any 24hr period) +  - worst case scenario [[electrical:12v:loads|loads]] (the max loads you will apply in any 24hr period((or at any given time, if you plan to run heavy loads))) 
-  - worst case scenario sunlight, usually December in your geographical area +  - worst case scenario sunlight, usually December in your geographical area due to shortest daylight hours 
-  - these factors will tell you the **cost of the install**+  - days of reserve (ie with no solar charging) you want 
 +  - whether or not you have access to other forms of charging: [[electrical:shore_power|shore power]], [[electrical:12v:alternator|alternator]], [[electrical:generator|generator]] 
 +  - These factors will tell you size of the system needed.  If the system you need will not physically fit on/in your vehicle, you will have to take a different approach.
  
  
-This approach also works for 'dwellers building **relatively minimal solar power systems** where one is not using all the available roofspace for panels.

 Some **luxuries** like [[hvac:solar_ac|A/C]] are impractical on typical solar installs and are therefore relegated to [[electrical:shore_power|shore power]] or [[electrical:generator|generator]] scenarios. Some **luxuries** like [[hvac:solar_ac|A/C]] are impractical on typical solar installs and are therefore relegated to [[electrical:shore_power|shore power]] or [[electrical:generator|generator]] scenarios.
