Question by Carrie: How many watts does my solar panel need to be if I am running lights only at night?
I want to use 12vDc rope lighting that is 3 watts per foot and i am looking to use approx 64 ft of light. I am probably only going to have the lights on for 3-4 hours at night.

Your numbers give 172 watts which at 12 volts is 14.33 amps. In theory, you would need to have a 57 amp hour battery, but auto batteries hate being completely discharged so you would either need a more expensive deep discharge battery, or a much higher amp-hour car battery or a cut off circuit to cut off the power when it dropped to about 10 volts (or both)
You didn’t say where you are, which is critical for the amount of light you get, especially if you are running this through the short dark days of winter. If you can only get 4 hours of good sunlight when you want 4 hours of night light, then you need at least 200 watts of solar supplied power and enough battery capacity to hold it from high to low voltage limits.
