[QUOTE="Gem in I, post: 591928, member: 7718"] Even with all the research WtN i'm still trying my head around it, the simpler the question the more difficult the answer. A-TEAM is on the ball. Personally i thought i had it covered with putting a house solar panel on the roof of my car. It has plenty of watts but not the amps required for 12v apparently you have to halve the amps of said capacity. example; My solar panel says max amp. 9.4 @24v. Halve that for 12v. and that's the optimum you get on a good day which works out to be 4 amps (rouphly) input as long as the sun is in your favour. Mine and every bodies fridge usually draws 3.5 amps to 4.5 amps an hour. So the next question is your battery? How long can it run at night before going flat/unusable? A 100ah battery will usually last 2-4 days from fully charged. [/QUOTE]
