Electricity Use With Solar Panels

AncientMariner
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.

    Now the FIT is zero, so small-scale rooftop installs make little sense to new buyers.  Instead of every house with a suitable roof being covered in solar panels, nobody is bothering any more.

     



    Although to be fair, the cost is also now pretty low as an initial capital cost.


    I'm planning a modest new build and using PV with a decent heat pump, thermal store for low temperature UFH and DHWS (with immersion top up) and a vehicle charge point shows some economic value regardless of the FIT payment


    I can get a 3kW "in roof system" with a 20 year guarantee on panels and invertor for about £4K fitted (and no need for MCS mark up on certification). By the time I account for the saving in roof covering and cost in for more integrated controls it will pay back well within the guarantee period. Not bothered by battery storage - just a big tank of warm water to do the same job


    Not sure it will save the planet - but it does provide a hedge against fuel cost escalation in the next 20 years.
