Is solar battery storage worth it?
Once the energy stored in your battery is used up, your home will once again be powered by the grid. Most modern storage batteries allow you to monitor your electricity generation and storage via an app or through an online account – some even let you access your system remotely and decide which devices you want your battery to power.
