The job of the grid is to deliver electricity to every customer at 120 volts and 60 hertz. This is accomplished by adding or removing current from the grid. A storage device helps by adding or removing current exactly when needed. Read on to learn how energy storage can strengthen the grid.

At this point, it''s worth noting depth of discharge. This refers to the amount of battery capacity you can use safely. For example, if a 12kWh battery has an 80% depth of discharge, this means you can safely use 9.6kWh. You should never use your battery beyond its depth of discharge as this can cause permanent damage.

PV cells, or solar cells, generate electricity by absorbing sunlight and using the light energy to create an electrical current. The process of how PV cells work can be broken down into three basic steps: first, a PV cell absorbs light and knocks electrons loose. Then, an electric current is created by the loose-flowing electrons.

Solar battery energy storage systems work very much like the more traditional kind. Photovoltaic (PV) panels capture the sun''s light, transforming it into direct current (DC) electricity. This electricity passes through an inverter, a device that transforms the direct current into the alternating current (AC) that is used by final users.

As mentioned earlier, photovoltaic solar energy systems are about 13% to 20% efficient on average, with high-end panels going up to 25%. Solar thermal panels, on the other hand, can go as high as 70%. Conversely, solar voltaic energy is more storable since solar thermal power often focuses on maintaining heat.

The inverter converts the energy just once, from DC to AC, as it flows from the battery to your home appliances. That leads to less electrical loss than with AC-coupled systems; DC-coupled systems are approximately 4-6% more efficient than their AC-coupled counterparts. Lopez points to increased efficiency as the main draw for DC-coupled systems.
