They don't have to know for certain. If they suspect, they can
switch out your old style meter that spins both ways with something
else. They have versions that don't spin backwards or electronic
versions that bill you for the amount of power flowing through them,
regardless of which direction it's flowing.

Progress Energy in Florida has some sort of wireless electronic meter
that can be read from out in the truck on the street. Guess they
couldn't find enough meter readers that could jump fences, wrassle
with pit bulls and read dial meters where every other dial turned a
different direction.

Gee, y'all are behind the times!  Our little hillbilly rural co-op has
installed electronic modules that read the wheel rotation of good old reliable
electromechanical meters and phones home about twice a day over the power
line.  Google for the "turtle system".

The only minor deficiency is that backward wheel movement counts as forward
power since the photo eye isn't direction-sensitive.  Not really a problem
here cuz I doubt that anyone is co-genning.  If someone ever does, they simply
install a separate meter that will ONLY turn backwards and subtract the two
readings.

Beware the lollipop of mediocrity. Lick once and you suck forever.

Come on, guys, THINK.  Just a little bit.  OK?

If he's using 20kWh a day and his itty bitty solar inverter is making 2kWh a
day, that means that his meter registers 18 kWh a day instead of 20.  It
doesn't turn backwards.  It simply turns forward a bit slower.  Duh!!!

The only time it could possibly turn backwards is if the total draw of his
entire house is <= 250 watts.  Chance of a fart in a whirlwind if he's using
20 kWh a day!

BobG, you know, the easiest thing to do with those 250 watts might be to power
an extra heating element in your water heater.  It MIGHT make up for standby
losses.

It isn't Global Warming.... It's Jerry Falwell arriving in hell.

Ahhhh, now there's an idea. Of course it still requires an inverter of
some sort... but I think I have just the thing to be honest, a 12 vDC
box intended to allow running of power tools off of car batteries.
Yes, I think I have a plan here...
