I am confused. When all the LEDs are powered up, what is the total wattage of ALL 200 LED modules . . .?

(144 or 60 watts)?

What size battery did you buy (amp hours) and what amperage solar controller? The solar panel might produce an average of 100 watts but a 12 V solar panel will not charge a 12 v battery. The panel needs to be a higher voltage. Put the panel in the sun and measure the voltage output.

Or - on the back of the panel, it may say what the short circuit voltage is.
