Battery Energy storage stores electricity as chemical potential energy, and is able to store the excess energy of a solar system. The energy produced during midday peak can be stored and used during cloudy conditions or night-time, making solar energy even more flexible.
With energy storage a site with a solar power plant can drastically increase its use of the energy it generates, to the point of never needing grid energy again.
Energy storage in a battery will make solar energy dispatchable, greatly augmenting electricity grid flexibility.
An energy storage system further increases the reliability of your system, acting as a buffer between your site and the grid. This means that any grid fluctuations like brown or black-outs do not affect your site, adding resilience.
A higher utilisation rate of your solar energy means much less energy procured from the carbon-intensive grid. Energy storage also replaces the need for a backup generator and stand-alone UPS systems, further lessening reliance on fossil fuels.
