Tesla isn’t the only one building batteries for your home. As Elon Musk and company trumpet the Powerwall, so many other outfits, including Samsung and Panasonic and LG Chem, are fashioning similar devices that can store energy for use when the power grid goes down or grid prices rise. So many are saying that, when paired with solar panels, their batteries can further reduce our dependence on fossil fuels, which still provide so much of grid’s power.
All are nice thoughts. But questions abound. Do the economics of these batteries really make sense? Are they worth not only the cost but the hassle of installing them? Are they worth it even if you don’t have solar panels?The ultimate goal here is to create vast networks of home batteries, all fed with solar energy and other kinds of clean power.
Orison, a small startup based in San Diego, wants to show that the people really do want these home batteries. That’s why it’s offering a rather friendly version of the technology via a new Kickstarter campaign. The device is unusually small and light, weighing only about 40 pounds. You can install it on your own, inside the house, simply by plugging into an ordinary electrical socket. And you can get your hands on one if you contribute a mere $1,600 to the Kickstarter campaign.
The device stores only about 2.2 kWh of power—which would, say, run your TV for 5 hours. But you can install additional devices for only $1,100 apiece. And each is designed to blend with a home’s decor. You can choose a device that hangs on the wall or one that stands on the floor, and both models double as an LED light fixture. No, you can’t have one today. But the company says its batteries will ship this summer.
