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?
