So, smart meters are probably as safe as any other technology we use today in terms of EMF radiation. But will they work with your solar array? When the technology was first introduced, smart meters did not always work with solar panels.
Smart meters are basically computers, and they hadn’t been programmed to know what to do when electricity was fed back into the grid. Instead of “spinning” (of course, there’s no dial to actually spin) backward to give users energy credits, they kept going forward — twice as fast.
This led to disturbing moments as new solar homeowners promised lower electric bills got bills double the usual amount instead. That glitch, however, was fixed quickly with new programming, but not before rumors about smart meters’ incompatibility with solar arrays spread, further fueling people’s dislike of the devices.
Be aware: If you use solar energy, the smart meter issued to you should have a sticker reading “net” — this means the meter has been programmed to run backward and credit you in kilowatt hours for the electricity you feed back into the system.
With the new programming in “net” smart meters, not only do the smart meters work fine with a solar installation, but a solar PV array helps you make sure your meter is working smartly for you.
