What is Battery Energy Storage?

2023-05-23 00:00

Energy storage has skyrocketing in renewable energy system because of that energy supply is easy to experience fluctuations due to weather, blackouts, or for geopolitical reasons. Thus, battery energy storage systems (BESS) are vital for utilities, businesses and residential to achieve a continual power flow.

What is solar energy storage?

A solar energy storage system is a technological solution in which batteries charge during the day when the sun is shining, and store and release power for consumption around the clock or on cloudy days.


Battery energy storage is particularly effective when combined with solar energy, because solar energy storage mitigates the intermittent nature of renewable power and guarantees a steady supply of electricity.


Modern batteries for a home or business solar energy system usually include a built-in inverter to change the DC current generated by solar panels into the AC current needed to power appliances or equipment.


Solar battery storage works with an energy management system that manages the charge and discharge cycles based on real-time needs and availability.


How does a battery storage system work in solar system?

The operation principle of a BESS is straightforward. Batteries receive electricity from solar panels, power station or utility grid, then store it as current to then release it when it is needed.


Common type of solar battery used for energy storage

  • Lithium-ion (Li-ion) batteries

  • Lead-acid batteries


Lithium-ion batteries

The most common type of battery used in energy storage systems is lithium-ion batteries. In fact, lithium-ion batteries make up 90% of the global grid battery storage market.

A Lithium-ion battery is the type of battery that you are most likely to be familiar with. Lithium-ion batteries are used in cell phones and laptops.

Lead-acid batteries

Lead-acid batteries are the most widely used rechargeable battery technology in the world and have been used in energy storage systems for decades. Lead-acid batteries may be familiar to you since they are the most popular battery for vehicles. They have a shorter lifespan than other battery options, but are the least expensive.

Lead-acid batteries are extremely eco-friendly; more than 90% of their material is recovered and the average lead battery is made-up of more than 80% recycled materials.

Lead-acid batteries have high technology and manufacturing readiness levels, but the cycle life is less than three years assuming one cycle per day.

In conclusion

Energy storage adoption is growing for a reason. The technology allows businesses and organizations to be energy-dependent, no longer tied to their local utility and its downfalls, including power outages and high energy costs.

Energy storage is the future and now is the time to reap the benefits of technology and renewable energy. The longer you wait to gain energy independence, the longer you spend more than you should on your energy bill.
