An ex-neighbour of mine has a PV system/battery that powers his
electric driveway gates. Cheaper than running a quarter mile of cable.
They are installed where it would be costly to provide an alternative
source of power

Where I live, such solar panels are often installed immediately under
existing power lines. For example, those flashing lights that sit atop
certain traffic signs; until recently, those lights simply had a short drop
of cable from the overhead power, but now have a solar panel. Abominably
stupid and expensive, but in keeping with the current tyrant's Green
dreams.

Yes, harry is as clueless as ever. *Probably 95%+ of the solar
installed
is at spots that already have power. * Here in NJ, in addition to
seeing
small ones on utility poles, there are bigger arrays on the roofs of a
lot
of homes and businesses. *They don't work without the grid being
alive.
If the grid goes down, you have no power.

Well ****fer that is intentional, it is a safety and cost thing.

Safety thing? *Cost thing? *Clueless as ever.
The essence of the problem is that without the
grid, the power from a solar array would vary all
over the place. *What do you think would happen
to your furnace or TV every time a cloud came by?

But you haven't the wit to understand this.
There are standalone systems but they are much more expensive.- Hide quoted text -

You haven't the wit to understand that those solar
panels mounted on utility poles by the power company
are obviously connected to the grid. *THAT is what
you were replying to.

Of course domestic PV are connected to the grid ****fer. How else can
power be exported?
One reason they are disconnected on power failure/outage to prevent
them feeding back into the grid and electrocuting whoever is making
the repair.

BTW, the ones on poles are not "obviously connected to the grid"
I can think of several reason why this might nor be so.
All of them to do with money.

Micro-power generation is beneficial because it can be connected to
the grid without needing to enlarge/modify the grid, the power
generated is used locally.
Also it is more secure, if one generator goes down,it's neither here
nor there.
