Re: If you have a PV Array then the last thing you want is a smart meter
you are getting confused between the standard electrical meter and the pv meter.
i have an old style spinning wheel leccy meter.
my energy company demands reads of this every quarter or whatever as per every other house in the country. i give it to them. they bill me.
when my panels overproduce (i.e they feed back into the grid because we use less leccy then we are currently generating) the wheel on the leccy meter runs backwards, undoing previous leccy we have used.
for the genration and fit - it is a separate digital meter, but it only calculates what we have produced from the array. this meter does not go backwards. i simply supply the number on the pv meter to the energy company,. they pay me 42p or whatever per kw generated (generation payment) plus about 4p per kw generated on 50% of each kw generation read (fit payment)
