# **How Second-Life Batteries Are Changing the Renewable Energy Game**
The transition to solar energy is in full swing, and one of the major challenges has always been energy storage. With the increasing popularity of solar panels for your home, homeowners and businesses alike are looking for affordable and sustainable ways to store excess energy. One emerging solution is repurposing retired electric vehicle (EV) batteries into stationary energy storage systems.
## **The Growing Need for Energy Storage**
Installing a solar array for home use is an excellent way to reduce electricity costs, minimize reliance on the grid, and contribute to a greener planet. However, without an effective energy storage solution, homeowners might not maximize the benefits of their solar investment.
During the day, solar panels generate excess power that can either be sent back to the electrical grid or stored for later use. In areas where net metering policies are less favorable or where energy independence is desired, having a battery energy storage system (BESS) is essential.
## **How Second-Life Batteries Are Solving The Storage Challenge**
Traditionally, lithium-ion batteries from EVs would be discarded or recycled at a high cost, even though they often retain about 80% of their original capacity. Startups like
