Everyone is super excited about batteries. Rightfully so, because they can provide a lot of savings and insure your investments against future rate changes. Batteries accomplish this savings by reducing your monthly demand charges and discharging the solar energy later during the most expensive times. Before you install a battery, you should consider your energy efficiency options first because they will also provide you with demand and energy savings. Energy efficiency paired with solar and energy storage is like installing a larger battery at a lower cost.

Batteries and other energy storage technology can provide significant savings to businesses and homes. They do so by strategically deploying the solar energy you produce at higher priced times. For businesses a battery also decreases the demand charges. For some tax incentives, the battery can only be charged by the solar energy system (or needs at least 75% to be charged by solar). How does a battery know when to charge/discharge the electricity? That depends on what type of battery you get.
