What wattage solar panel required for AC 1000 watts
If the average power consumed by your household is 1 kW, you'll need about 6 kW of solar panels to supply this. This is based on the fact that in most environemnts, solar panels can produce their full power for about 4 hours per day, on average.

You'll also need a storage system that can store enough energy for several days of poor sunlight, and an inverter that can supply the peak power that your household needs at any given time.
