There are several types of battery storage systems that are commonly used in commercial settings, that work in unison with existing solar. The most common types of battery technologies used in commercial applications include:
- Lithium-ion batteries: Lithium-ion batteries are one of the most common types of batteries used in commercial settings due to their high energy density, long cycle life, and low maintenance requirements. They are used in applications such as peak shaving, load shifting, and frequency regulation.
- Flow batteries: Flow batteries use liquid electrolytes stored in external tanks and can provide long-duration energy storage. They are often used in applications where longer discharge times are required, such as in renewable energy integration or grid stabilization.
- Sodium-ion batteries: Sodium-ion batteries are an emerging technology that has the potential to be used in commercial settings. They offer a lower cost alternative to lithium-ion batteries and can be used in applications such as grid-scale energy storage.
- Lead-acid batteries: Lead-acid batteries are an older technology that are still used in some commercial applications due to their low cost and high reliability. They are often used in backup power systems or in applications where short-duration energy storage is required.
- Nickel-cadmium batteries: Nickel-cadmium batteries are a mature technology that is still used in some commercial settings, particularly in applications where high reliability is required. They have a long cycle life and are often used in backup power systems.
Ultimately, the choice of battery storage system will depend on the specific requirements of the commercial application, including factors such as the required capacity, discharge time, cycle life, and cost.
