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.
