I use about 1000 kilowatts a month in summer and 1200 kilowatts in the winter. This is really not very much, but I would like to cut it in half. I am thinking of a direct grid tie. My small house draws about 1000 watts during the day/night hours during summer and 1200 watts during the day/night in winter. These are averages I have taken with a meter.

What would be the total watts I would need in solar panels to cut my kilowatt use in half using direct grid tie?

Would the Enphase Micro inverter or the SMA Sunny Boy 700u work for me? Where do they tie-in to my grid?

Thanks
