Introduction
Residential solar energy storage systems are becoming increasingly popular as homeowners seek:
- Lower electricity bills
- Backup power during outages
- Greater energy independence
Batteries are a key component of these systems because they store excess solar energy for nighttime or emergency use.
Lead acid batteries remain widely used in residential applications due to their:
- Affordable pricing
- Proven reliability
- Simple installation
How Residential Energy Storage Works
During daytime:
- Solar panels generate electricity
- Excess energy charges the batteries
At night:
- Batteries supply stored electricity
During grid outages:
- Batteries provide backup power
