Only if you are not interested in being paid the Feed-in tariff.
To be eligible, you have to use both approved components and

I really don't know a lot about this subject, other than what I've read in
general, but just to fling a curved ball in for a moment, if the OP's sister
is intent on having panels on a less-than-ideal-facing roof, wouldn't she do
better to make them water-heating panels ? I seem to recall reading that the
energy saved on fuel for heating the same water, is quite significant, and
that the installation costs are not that high. If the fuel saving *is*
significant, then I would have thought that with the very high energy costs
that we suffer now, the 'effective' returns might be quite good, without the
hassle of having to sell energy back via a government scheme of dubious
longevity, and without the inherent progressive efficiency reduction that
comes with PV panels. Anyone here clever enough to do the comparative sums ?
I'd be quite interested to know this for myself.
