In the UK those of us who installed solar early are paid a subsidy for every KWh we generate whether it is exported or not (in the basis that we save the country from having to build a new power station). We are also paid a small fee for each KWh exported, where in most cases to save the cost of an export meter it is assumed that the house uses 50% of what it generates and the rest is exported.
There is a catch. if like me you installed the maximum 4KW solar array to begin with, and later add more panels (as I have just done), the subsidy only applies to the original 4 KW setup.
Is there a simple way for me still to have PVOutput calculate the money side (which it does so well) while limiting the amount on which there is a subsidy to either the ratio of 4 KW to my new total system capacity (ie pro rata it) or alternatively using the Solar Edge inverter which only supports the original 4KW panels?
