There may not be a simple answer to this but the question was asked at a recent IAEI meeting on Solar and the only answer was "magic".
Typical residential solar arrangement interactive with the grid.
Assume a solar available output of 100 amps at a particular time of day..
Residence load happens to be zero.
Solar company states the 100 amp available solar power will flow back to the grid through the solar meter.
When load is on the grid why will the full capacity of the solar flow into the grid rather than the load being satisfied by the other utility generation units ?
