Last time I looked at solar panel threads there was an overwhelming view
that it just didn't make financial sense and the calculations generally
didn't take into account the fact that you had to recover your capital and
the interest on your capital (if you just saved/invested it) to break even,
before you started to make any savings.

Now the recent discussion seems to be more about the immoral use of the
subsidies than about the sums not adding up.

When did this change?

Is solar power now a reasonable prospect subject to the usual caveats about
unproven long term technology and untrusted long term government policy?

Having a large south facing roof is making me wonder if I should get some
quotes.
Also a couple of friends who are generally financially savvy are going down
this route.

Cheers
