Solar battery storage like Tesla Powerwall can be useful for homeowners even without solar panels as they are paired with a typical solar energy system of your home. By using the technology of a small scale energy storing system in the storage system of the solar batteries at your home, your battery can provide backup even without solar panels as it will be charged by the power supplied by the grid.
The need for solar battery installed in your home depends mainly upon how your solar power can adjust your utilities. Full net metering is offered by most of the utilities, which allows you to get credit on your power consumption bills for every unit of electricity produced by your solar panels. So, if you install a solar battery, then you may not be able to save more money on your monthly electricity bill.
But, a solar battery can increase the savings on the solar panels installed in your office or home in many circumstances. If you have to pay demand charges at the rate of the time to use or net metering is not offered by your utilities, then you can save a lot of money by using solar batteries.
Though the technologies used to store solar energy have not gained enough popularity, still you cannot ignore them in the present time. The demand for saving energy is increased at a faster speed because of the benefits provided by solar batteries to the homeowners. The ability of the solar batteries to store renewable energy to use later on can also be used for the entire grid of electricity if used on a large scale. The technologies of energy storage used in solar batteries can provide flexibility to the users of energy to generate electricity with the help of solar power and use it.
The task of grid managers and electric utilities is a bit more complicated. They have to provide reliable and constant access to electrical power to their customers to power their businesses and homes. And for this purpose, they will have to be sure that the grid has enough ability to meet the needs of their customers. Most probably, their customers may not get any power supply at a point of time if the system has too much or too low power supply.
It can be more challenging to balance the demand and supply carefully if the grid is combined with the sources of renewable energy as solar panels can produce electricity only when the sun shines. The output of the causes of renewable energy cannot be increased with the increase in demand like the traditional power plants based on natural gas or coal, as you cannot compel the sun to shine brighter to produce more energy or shine at night.
In this way, the flow of electricity from the sources of renewable energy can be increased by installing more technologies to store energy like solar batteries, etc. In other words, battery storage at your home can provide your power supply even without solar panels.
