Storing energy from solar panels will require a solar battery. A solar battery will help you store your solar energy and effectively help you save more on costs. Due to NEM 3.0 and the changes it brings, you will no longer be able to save as much from just solar panels alone because the rates will be reduced if you send the solar energy back into the grid. A solar panel installation is best paired with a solar battery. Most companies will be leveraging smart battery technology and produce energy off grid to be used at interval periods where electricity demand is lower.
