To date we have accumulated about 40,000 kWh stored excess in the grid after almost 2 years of grid connected operation while powering 3 homes. Our local utility has taken about 12,000 kWh of this total to pay for our use of their wires to SEND them the power. They assess DEMAND / DELIVERY charges regardless of which way the power flows. At least they finally stopped taking our $ and are now just taking our stored kWh's to pay the commercial demand / delivery charges.
