hi
solar depends on usage patterns and electrical loads .
The theory and modeling suggest this ,,
never discharge battery below 50% depth of discharge DOD
A low volt cut is essential set it at 12.oovolts [50% dod] provides a reasonable batt life
This gives u 60 amps usable
Consumption is around 1 amp per litre per in hot weather
cool weather less and bloody hot as a freezer more
eg av. consumption 40 ah by the fridge
20 ah by all the other items recharger lights etc etc
60ah consumed
Peak sun hours look it up on google
varies 4hr to 7 hr depends upon location and season
PSH 5.5 hrs per day
solar available
say 5.5amps per 100watt
120w = harvest 6.6 amps /hr x 5.5 psh = 36.3 less 20%
150w = harvest 8.25a /hr x 5.5psh = 45.4a '' ''
200w = harvest 11a/hr x 5.5 psh = 60.5a '' '''
solar system are around 80% efficient
All of a sudden 150 watt as an absolute minimum setup is where u would start .
Try to get tri folds as they can be easier to carry especially in the 200w unit
[ in saying that 6mtrs from
camp is not far] .Depends upon your ability .
vehicle to van battery charge set up [so u arrive fully charged ] Small cable means way way longer charge time
240 volt charger 20amps plus and generator if needed
