read this carefully, because i won't be repeating myself
i will answer this one question for you, then you will address the question i presented to you. should you decide not to, i am done with you and will consider you a troll or worse an idiot.
the choice of which will be mine.
your question: "#1. Do batteries stand a better chance of being fully charged with two, three or four days of Sun (Solar Charging) than in just one day of Sun? Yes or No.
my answer: yes, no, maybe and it depends!
it all depends on so many other variables that you seem oblivious to.
if i had a 1000amp hour battery that was depleted to 50% state of charge, and a 100watt solar panel, then "yes" i will certainly take far longer than a day to recharge the battery...
if on the other hand i have a 100amp hour battery and it is depleted to 50% state of charge, and i have a 1000watt panel, then "no" it won't take 3 days to recharge the battery
but then again... and this is very important
what if you don't have good sun exposure? what if you have a week of cloud cover? what about after a hail storm? then "maybe" you ought to consider other methods of charging? other charge regimes?
and equally important when it comes to system design
"it depends" on how your system is designed, to what level of discharge are you planning to take the battery bank as an example. what level of charging efficiency are you willing to accept, how many kw/hrs are you targeting over the life of the battery bank, how often does the battery bank really need to be fully recharged and still fully recover with periodic equalization, all of these questions would need to be answered (among many more) before you could determine how long it will take to effectively recharge your battery.
so there you have your answer, that being "yes, no, maybe,
and it depends"
so now it is your turn to focus, as hard as it might be for you to do so, go back and reread my prior example and lay out how your approach is superior to what everyone else on the planet is doing.
remember you are the one that claims everyone else has been doing it all wrong for the last 100 years!

ps. lets both stop the useless rhetoric ok? this sort of thing really adds nothing to the discussion, and at least as far as i am concerned it has no effect on me... the thing is that almost always and without exception, one that resorts to such tactics is soon proven to be very short on facts or does not have a clear grasp of what he is talking about. i can play it either way, but thought i would at least offer the opportunity to make this a more productive discussion. Besides i have already been called every name in the book, after all i do have a nasty exwife, so there really is nothing you can call me that will have any affect on my ability to continue my end of the argument.
a good friend of mine once stated
"bob, don't argue with a pig, because soon you will learn that the pig loves it"
i am not suggesting you are a pig, however i fully realize that i may be!
