Coupling solar batteries with solar arrays is a relatively new practice. The advantage of doing so is four-fold. First, a solar battery stores the energy generated during sunlight hours and makes it readily available for use during non-production hours, such as at night or on cloudy days, essentially enabling your home to run on 100% renewable solar energy around the clock, as long as electricity demand does not exceed the supply that the battery can provide.
Second, a solar battery storage system can lower your energy costs significantly. By charging the solar battery during off-peak hours and discharging it during peak hours, you can avoid paying a lot for electricity from your utility company. The savings from this can serve towards reducing your solar battery storage system costs.
Third, you can earn money by selling the energy stored in your solar
battery back to the electrical grid when electricity prices are at their highest—if your
utility allows net metering. Lastly, by adding a solar panel battery to your solar system, you can choose to be independent from the national grid at any time, thereby ensuring energy security for your household.
When Is It Ideal to Install One?
A solar battery storage system is best used in combination with a solar PV array. Lucky, if you already have an existing array, it is a relatively simple task to add a solar battery into the mix. And if you have neither, the two systems can be bought in tandem to make your home run entirely on renewable energy.
The two technologies complement each other to bring down your solar battery storage system costs by making your solar panel array vastly more efficient. If you have been considering going green, there is no better time to start taking advantage of the money you can save on your monthly electricity bill.
Solar battery storage systems offer a variety of types of solar batteries for you to choose from and many advantages, like more eco-friendly, longer lifespan, and easy to install.
How Much Does a Solar Battery Storage System Cost?
Currently, solar battery storage system costs typically range between £1,200 and £6,000 depending on the capacity, chemical composite of battery, and its life cycle.
Solar battery storage system costs are in a similar situation like when the technology for solar panels was new. As the adoption of solar battery storage systems becomes more widespread, their price will naturally follow the same declining trend as solar panel costs.
Lithium-ion solar batteries are the most mainstream and cost-effective batteries of all kinds. The table below provides a rundown of lithium-ion solar battery storage system costs based on usable capacity.
