Solar power / best electricity supplier

Ciprico

We have just installed solar PV (3,8Kw). Looking at the various comparison sites to find the best gas/electricity suppliers - can't find one that factors in solar power. I realise the FIT is fixed, but the cost of units fed back can vary. Also having solar power obviously changes the pattern of consumption (shift from daytime to evening grid usage).

Some companies measure returned power, some assume 50%. For measured power I supposed "someone" has to pay for the meter...

I guess I don't want Economy 7 as all appliances will be programmed to be on during daytime, our peak power use will be early evening - and E7 doesn't cut in till late at night

Has anyone done any research on which suppliers are best geared up to accomodate solar "contibutors", I imagine we all have the same issues....

Many Thanks
