Why don't the government give an increased FIT for East/West array?

This would significantly smooth out the solar peak and encourage a much
greater up-take by the large percentage of folks who don't have an
optimal SE through SW facing roof.

People moan about the cost of FIT being borne by the rest of the
population but surely it's better keeping payments to UK residents
rather than the next generation of foreign investors e.g. China-land
who's building Hinkly C reactor?

Obviously still need an "on/off solution for night and cloudy days but a
smoother solar PV curve from encouraging East/West panels seems to make
sense to me..
