Solar battery storage is revolutionizing how homeowners use solar energy, allowing you to store excess power for use at night or during peak rate periods.
Why Battery Storage Matters
Traditional solar systems generate power during the day but rely on the grid when the sun sets. Battery storage eliminates this dependency, providing:
- 24/7 solar power usage
- Emergency backup power
- Peak rate period shifting
- Grid independence
- Increased system efficiency
Popular Battery Options
- 1. Lithium-ion Batteries
- Most efficient and durable
- 10-15 year lifespan
- Cost: $8,000-$15,000 for 10kWh
- 2. Lead-acid Batteries
- More affordable
- 5-7 year lifespan
- Cost: $3,000-$6,000 for 10kWh
- Investment Considerations:
- System capacity needed
- Budget constraints
- Payback period analysis
- Potential government incentives
Battery technology continues to improve, making this an excellent time to consider storage for your solar system.
