Most Popular Home Energy Storage Systems
For homes, the most popular energy storage systems are primarily based on battery technology, with a focus on lithium-ion batteries due to their efficiency and compact size. Here are some of the most common types:
1. Lithium-Ion Batteries
- Dominant Market Share: Lithium-ion batteries are the most widely used residential energy storage solution. They offer high energy density, fast charging, and long lifespans, making them ideal for storing excess solar energy.
- Examples: Tesla Powerwall and LG Chem’s RESU are popular options among homeowners.
2. Lead-Acid Batteries
- Affordability: Despite their lower energy density and lifespan compared to lithium-ion, lead-acid batteries are still a cost-effective choice for residential energy storage.
3. Flow Batteries
- Long-Duration Storage: Though less common in homes due to cost and space requirements, flow batteries are gaining attention for their long-duration storage capabilities, making them suitable for larger residential systems.
4. Other Solutions
- Sodium-Sulfur Batteries and Supercapacitors: These technologies are less common but offer unique advantages in terms of efficiency and fast charging.
- Franklin Home Power: Offers a comprehensive home energy management system integrating solar, battery, and grid power sources, focusing on whole-home backup capabilities.
