# The Growing Role of Battery Storage in Solar Energy
The solar industry continues to evolve, and one of the most exciting developments is the rise of battery storage. As solar companies deploy more solar panels for your home and businesses, energy storage has become an essential part of how we use solar power.
### Why Battery Storage Matters for Solar Energy
Traditionally, one of the biggest challenges with solar energy has been intermittency—solar panels generate power during the day, but energy demand often peaks in the evening. Without battery storage, excess solar energy goes unused or gets curtailed, meaning it’s wasted. However, new data shows that batteries are now regularly capturing surplus solar energy and making it available when it’s needed most.
According to recent research, battery storage capacity in the U.S. likely surpassed **30 GW by the end of 2024**, with an additional **15 GW expected to be deployed by the end of 2025**. This rapid growth is changing the way the electricity grid operates.
### How Batteries Are Transforming the Grid
Battery storage is no longer just a backup solution. It’s now a crucial part of daily power grid operations. Data from regional grid operators highlights several key trends:
