I want to charge up to a 12 volt battery. How long can I use a heater and refrigerator?

or how many watts? i dont use much electricity. i have on a couple of lights and a computer, sometimes the tv. how many solar panels would i need to power those constantly throughout the day, and maybe charge batteries for night? the air, refrigerator and hot water heater i would still use regular electricity.

have them on your home. my house is about 1700 square feet. About how much would it coast me to go completely solar? i have ac, water heater, couple of televisions,refrigerator and all that good stuff.

How many hours can I charge it up to use a heater and refrigerator per hour?
