I think it's the other way round as your reputation on here would appear
to confirm.

There's no point in continuing with this. I have panels on two roofs and
no tiles were cut or ground...

Tiles/slates are removed and pedastles are fixed to the common
rafters. The tiles are put back round the pedastles trimmed as
neccessary with lead flashings.

Rails are fixed to the pedastles and the panels are fixed to the
rails.

You are right, there are cowboy methods.
One is they drill through "fake slates" and fix to the intersection
point where a batten crosses a rafter. The pedastle goes on top with a
rubber seal.

This may be fine if the hole is not near a perpend, but if it is the
roof leaks.

You can also get integrated systems that replace tiles. They are less
efficient as some cooling effect is lost. (They generate more in cool
weather.) More suitable to new builds.

Thinking of getting some Arfa?
You better be quick, the rate is being cut to £0.16 on Aug 1st 2012.
There is no guarantee the price of panels will fall as it did last
time there was a big cut.

OK on all that, and the answer is a resounding NO ! I hate the bloody
things
and think that they are one of the most incongruous things to come along
and
blight the look of pretty villages. I also think that it is absolutely
wrong
that they can just bypass planning because of their so-called 'green'
credentials. I know you love yours, and you believe in their savings and
so
on, but put them on my roof ?

Never ...

they fulfill a useful function in preventing people's wild notions from
impacting on others ...

You only have to look at countries that have a free-for-all planning

always go our personal way.

You don't need planning permission unless it is a listed building or
conservation area or bigger than 4Kwp or projects above the roofline.

Are all thatched cottages listed?
Could be a new building I suppose in which case no recourse.

and, IIRC, you allowed to raise the roof by 150mm in the process, without PP.
