Modern leccy meters are designed not to record reverse power flow. Most old fashioned ones with a rotatey disc would turn backwards if you were generating more than you used.
When you have solar panels installed there has to be a generation meter so that you can get the Feed-in Tariff payments. I also have a "Sunnybeam" box which is linked to the inveter by bluetooth. It gives a full record of generation which I can dowload to a PC.
What I can't see from my installation is how much of the solar power I use and how much is exported. For a domestic installation it is assumed to be half and half for the purposes of the export tariff. To measure exported power you would need an export meter which is normally only fitted to larger installations.
