Assuming you're on FIT, this is extremely expensive because you
will be losing 43p/unit that you put into your storage heaters,
but it will only cost you low rate (no idea, 6p/unit ?) to run
them at night on E7.

I know that sounds stupid, but it's because of the frigged solar
panel scheme - you are being paid much more for your solar energy
than it's worth. You need to minimize your own energy consumption
when the panels are generating, and try to use energy when they
aren't.

If you really want to heat the house using solar, you need to use
solar water heating into a thermal store. That way you are making
much more efficient use of the energy, because you aren't going
through the phase to convert it to electricity, which is very
inefficient in solar panels.

You get the £0.43 whether you export it or use it.
