Before talking about solar batteries we need to talk about Smart Grid.
What is Smart Grid?
Smart Grid is the modernisation plan of the national energy networks. Many countries, including Great Britain, are designing plans to modernise the energy networks in order to be able to integrate more efficiently green energies and to better tackle power outages.
The national energy networks are becoming obsolete, we’re now using much more energy than when these networks were built and at the same time we need to find ways to reduce the carbon emissions.
The Smart Grid concept will integrate all the energy suppliers (also domestic suppliers) in order to create a better network, using and generating energy in an smarter way.

What does this mean for the owner of a Solar PV system?
Following the Smart Grid plan, if you have an existing Solar PV system in your household or warehouse and you add a battery storage device you can not only store surplus energy from the solar panels, but also accumulate energy when prices will be lower (off-peak) and use your stored up energy when prices are higher (peak times). Furthermore, you could sell the extra energy generated to suppliers at these peak times at a higher rate.
Energy suppliers can’t really store the excess energy they produce and are currently throwing it away which is a tragedy for the environment and for the economy. At the same time, during the peak times, they can find themselves in a difficult situation since they might not be able to keep up with the increasing demand.
This is why it’s important to implement Smart Grid so we can better match supply and demand needs and avoid this waste of resources and money.
Nowadays, installing a solar battery with your Solar PV system generate up to 75% savings on your energy bills. In the near future with the increase of energy costs and with the possibility of selling energy at peak times, these savings will be much greater.
