Does Your Meter Really Run Backward After You Install Solar?

If you have an old-school analog meter, it really will.

When your PV system makes more power than your home uses, your electrical service meter reverses — you can watch it go backward.

However, utilities have moved to digital metering. These will not give you the satisfaction of watching the meter spin backward, although the backward-pointing arrow on the digital display elicits some joy. If you do have an old analog meter, the utility will replace it with a new digital one a few days to a month after your system is installed.

We captured this meter spin backward after an installation…pretty cool.
