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. |

| Sizing **off-grid solar configurations for campers** has many more variables: |
| |
- 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 [[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))) |
- whether or not you have access to other forms of charging: [[electrical:shore_power|shore power]], [[electrical:12v:alternator|alternator]], [[electrical:generator|generator]] | - 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 [[electrical:solar:sizing#maxxed_system|a different approach]]. | - These factors will tell you size of the system needed.

**Example:** You need 100AH x 1 day, so your bank will be 200AH cycled 50% each day. \\ | **Example:** You need 100AH x 1 day, so your bank will be 200AH cycled 50% each day. \\ |
**Example:** [[electrical:12v:lifepo4_batteries_thread|LiFePO4]] can be drained down to 80%-90% DoD so you would need only 110AH of rated capacity with that chemistry. 120AH if you are conservative. | **Example:** [[electrical:12v:deep_cycle_battery#lithium_chemistries|LiFePO4]] can be drained down to 80%-90% DoD so you would need only 110AH of rated capacity with that chemistry. 120AH if you are conservative. |
