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.

My my calculations the exact same applies. I.e. no ROI of any real validity.
F in law did this, and the numbers make no financial sense, and after 6
months the builder next door had covered them in cement dust, they
barely work and there is argument about who is going to pay to have them
cleaned/glass replaced etc etc.
