Solar batteries can be divided into six categories based on their chemical composition: Lithium-ion, lithium iron phosphate (LFP), lead-acid, flow, saltwater, and nickel-cadmium.
Frankly, the first three categories (lithium-ion, LFP, and FLOW) make up a vast majority of the solar batteries available to homeowners. However, battery technology is evolving at lightning speed we will focus of the .
- Lithium-Ion Batteries: Popular in modern solar systems, lithium-ion batteries offer a higher depth of discharge and longer lifespan. They are more compact and efficient but come with a higher upfront cost.
- lithium iron phosphate (LFP) batteries: technically fall into the category of lithium-ion batteries, but this specific battery chemistry has emerged as an ideal choice for home solar storage and therefore deserves to be viewed separately from lithium-ion.
- Flow Batteries: Innovative and long-lasting, flow batteries are ideal for large-scale energy storage. They have a longer lifespan and can be fully discharged without damage, but they are less common and more expensive.
| Feature | Lithium-Ion Batteries | Lithium Iron Phosphate (LFP) Batteries | Flow Batteries |
|---|---|---|---|
| Lifespan | 10-15 years | 10-20 years | 15-20 years |
| Efficiency | 90-95% | 90-95% | 70-80% |
| Safety | Moderate (risk of thermal runaway) | High (more stable, lower risk of thermal runaway) | High (non-flammable, stable) |
| Size (Compactness) | Compact and lighter | Slightly larger and heavier than Li-ion | Large and heavier |
| Cost | Higher initial cost | Moderate initial cost (generally cheaper than Li-ion) | Highest initial cost |
| Depth of Discharge | High (up to 95%) | High (up to 95%) | High (100%) |
| Energy Density | High | Moderate | Low |
| Maintenance | Low (minimal maintenance) | Low (minimal maintenance) | Moderate to High |
| Best Use Case | Residential, Commercial, Industrial | Residential (particularly where safety is a priority) | Large-scale energy storage, Industrial applications mostly |
| Environmental Impact | Lower (no toxic materials) | Lower (no toxic materials, safer chemistry) | Low (non-toxic, recyclable) |
