How to do Solar - Update on Batteries and Charging

How to wire in the solar panels, how to charge the batteries on limited or no sun light. Just how hard it is to really charge a 200 AH battery. They say 600 watts of solar for five hours will charge one battery. Which is just NOT true. 600 watts for 12 hours won't give them a full charge. And they charge the best if NOTHING is using them during the charge. All day with 600 watt panels and about 5 hours of generator gets them close.
