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?

I don't think it did.

ISTM that the people who think that "the sums don't add up" still think
that.

The fact that commercial operations think otherwise suggest that the
negative opinions are formed from out of date data. *I certainly see people
make comments such as this is "immature" technology when in fact PV cells
were invented more than 30 years ago and the technology is anything but
immature.

"PV cells" been around a *lot* longer than that. The modern technology
is *certainly* immature.

If I had a suitable roof, I wouldn't enter into any deal other than one
where the installer takes all of the risk.

And sign away the rights to your roof. I certainly would not buy a
house with copnditions like that attached.
