Electricity Use With Solar Panels

I have just been asked about solar panels in a domestic environment and not wanting to guess and likely get it wrong, thought best to ask here.


With solar panels are you paid for what you generate in total, ie the output from the inverter? Or are you paid for the net amount that you actually export ie the difference between the inverter output and whatever is being used in the property?  


Thanks.

  • In principle it's a bit of both - I get 40-odd pence per kWh generated (regardless of where it goes) plus a few pence per kWh exported.


    But because the value of the export is so low, for most domestic installations it's not worth installing an extra meter to measure it - so the system "deems" export to be 50% of generation. So mostly in practice it amounts to being based all on the total generation readings but at a slightly higher rate (i.e FIT p/kWh + 50% of  export p/kWh). That might change when they get smart meters sorted out properly so they can record both import and export.
