I am grid connected. The utility only banks for the following month and make adjustments kilowatt hour for kilowatt hour. I take care of my dad and with a 3500 watt system have never gotten close to producing a surplus kwh.
His oxygen concentrator, de-humidifier, and window air conditioner add up. The system does however have an effect on the electric bill.
I am in Kentucky and we do get a good dose of cloudy weather. I am planning to add another 600 watts of PV to compensate.
Thanks for all the replies. I guess the answer is (It depends).
