Here at HQ we are pretty excited about the new Powerwall from Tesla Energy that was just announced last week, but that doesn't mean there aren't some negatives to the new tech. Some new details have come to light suggesting the initial version will not be quite as disruptive as originally thought.
First, Tesla's solar energy company, Solar City isn't ready to endorse the Powerwall for use with their systems yet. Apparently, this first iteration wasn't designed to offer anything useful to Solar City customers because existing regulations allow users to sell unused energy back to the power companies. This means that the economics of the Powerwall simply do not yet make sense when used with the Solar City solar energy technology.
The second detail which throws a bit of shade on the Powerwall is that only the smaller 7kWh is designed for everyday use. According to reports, the 10kWh version isn't designed to go through more than about 50 charging cycles a year. The only advantage of this version of the Powerwall for folks with the Solar City tech would be as a battery backup device.
Of course, for the average homeowner who does not have a solar panel setup for their home, the 7kWr Powerwall is still an affordable way to lower energy costs, it's simply ironic that Elon Musk's own Solar City solar power tech company isn't ready to use the tech with their existing systems.
