They also require more maintenance. Think of them as the reliable workhorse, but not the most glamorous. There are two main types of lead-acid batteries used in solar storage: flooded and sealed. Flooded lead-acid batteries are the most common and require regular maintenance, such as adding water to the cells. Sealed lead-acid batteries, also known as valve-regulated lead-acid (VRLA) batteries, are maintenance-free but tend to have a shorter lifespan. Lead-acid batteries are more sensitive to deep discharges than lithium-ion batteries, which can significantly reduce their lifespan. They also have a lower energy density, meaning they require more space to store the same amount of energy. However, their lower cost makes them an attractive option for some applications, particularly in off-grid systems where budget is a major concern. They have been around for a long time and the technology is well-understood, making them a reliable choice for those who are familiar with their limitations.

Flow Batteries

Flow batteries are a newer technology that's gaining traction. They store energy in liquid electrolytes, which are pumped through a cell to generate electricity. They have a long lifespan and can be scaled up to store large amounts of energy. Think of them as the up-and-coming contender. They are different from other types of batteries in that the energy is stored in external tanks of electrolyte solutions. This allows for independent scaling of power and energy, making them suitable for large-scale energy storage applications. Flow batteries have a long cycle life and can withstand deep discharges without degradation. They also have a high round-trip efficiency, meaning they can store and discharge energy with minimal losses. However, they are typically more expensive than lithium-ion and lead-acid batteries, and they require a more complex system design. They are often used in commercial and industrial applications, such as grid stabilization and backup power for critical facilities. The technology is still under development, but it has the potential to play a significant role in the future of energy storage.
