How many batteries can a 200-watt solar panel can charge?
How much power can 200 watts generate?
A 200-watt solar panel can generate up to 900Wh in a day in states with peak sunlight between 4.5 and 5. Whereas, in states where the peak sun hours are between 3.5 and 4, a 200-watt solar panel can generate up to 560Wh in a day.
Here peak sun hours differ from daylight hours. Peak sun hours are defined as the time of day when the intensity of sunshine is greatest. In other words, most electricity is generated by solar panels during peak sun hours. Refer below map showing the peak sun hours per day in different states of the US.
Now, for ease of your understanding, we have prepared a map for your quick reference that illustrates how much electricity a 1 kW solar system may produce each day in various US states. >> Refer to the below map.
From the above map, you can calculate how much power can a 200Watt solar power generate in your state, or you can do reverse calculations to find out how much solar you need to generate any specific amount of power.

Can a 200W solar panel charge a 12V battery?
The open circuit voltage of a 200 W solar panel is 24V, hence you cannot connect it directly with a 12V battery. You will need a charge controller to charge 12V batteries from a 200-watt solar panel.
Here, open circuit voltage is the maximum voltage across the panel terminal at no load. Once the load is connected across its terminal, the voltage will drop to nominal voltage.
During the charging of batteries, the internal resistance of the battery reduces as it gets charged. Therefore, once the battery is fully charged, its internal resistance will be too low for the solar panel and it will act like an open circuit. Hence, charging a 12V battery directly with a 200-watt solar panel is not recommended.
Can a 200W solar panel charge a 200Ah battery?
You cannot fully charge a 200Ah battery from a single 200-watt solar panel in a single day. In a single day, a 200-watt solar panel with a charge controller can charge up to 33% capacity of a 200Ah battery.
Moreover, if you have a 24V, 200Ah battery, 200 watts can charge only 16% of it in a single day. Because the amount of power stored in a 24V battery is 2 times more than 12V of the same Ampere-hours rating.

How long does it take a 200-watt solar panel to charge a 200Ah battery?
One 200-watt solar panel will take 15 hours of peak sun hours to charge a 12V, 200 Ah battery. Furthermore, to charge a 200Ah, 12V battery in one single day, you will require 3 numbers of 200-watt solar panels with a charge controller.
How many batteries can a 200-watt solar panel can charge?
In a single day, 200 watts of solar panels can charge 65Ah, 12V battery for the state with 4.5-5 peak sun hours. Moreover, for states with 3.5-4 peak sun hours, 200 watts of solar panels can charge only 40Ah, 12V battery in a single day.
