It's all part of the clutching at straws syndrome these retards are
They get even worse with wind turbines. (Drivelish claims they chop darling
little bats and birds to pieces and "flicker" etc.)
There's only one argument against mega size PV ground arrays and that's
about it taking up agricultural land.
Personally I think all PV should be on roofs when it's taking up no space.
And furthermore, everyone should be compelled to have one.
Does that allow for the rather poor insolation levels in winter ?
Wonder why more don’t have some simple variable angle
system so you can have say just two, one that is best for
winter and the other for summer etc and just manually change
between them twice a year. Trivial to do mechanically.
Have you ever been in one of these places? or been close up?
Well the first one I linked to certainly is, I went inside it last
I suppose that they might have used polycarbonate gazing at thanet
earth, but seems unlikely.
This article says it uses glass with a lower iron content for maximum
light transmission(which matters for this sort of thing)

There aren't any to notice around here, no poly tunnels either. The
closest I see near here is plastic sheet laid on tilled, and
presumably planted with something, ground with edges buried to stop
it blowing away.
Up here it's either enclosed grazing or open moor grazed by sheep and
maintained for grouse.
I've seen aerial pictures of the large glasshouses in the deep south,
they don't look like poly tunnels to me but greenhouse type
structures but on a massive scale.
18 hectares, pitched glass roofs (rooves?).
You do get large polytunnel structures, but AIUI commercially they are
used more for growing plants which benefit from a bit of extra
protection, to extend the growing season, or protect from bad weather,
so things like soft fruits.
They aren't so suited to the optimum growing of young plants in
nurseries, or tomatoes etc. Light transmission isn't so good, and they
can't control the temperature, etc. so well.
Not if you do it yourself. Doesn’t in fact add
anything to the price at all when you do it right.
Doesn’t need to have any more materials at all when
done in steel, just a couple of holes drilled and put a
welded on bolt thru there to act as the hinge.
Again, not if you diy it. More certainly but not 6 times
the price given that the bulk of the cost is still the panels.
Big on strawberries/other soft fruit round here.
To get out of season fruit.
The edges are rolled up in summer to control temperature.
We have acres of them.
Big issue, lots of NIMBYs whining round here.
