🔋 Introduction
For solar energy storage, battery lifespan is everything.
👉 The longer it lasts, the lower your cost.
📊 Battery Types Compared
| Battery Type | Cycle Life | Lifespan |
|---|---|---|
| LiFePO4 | 4000–6000 | 10–15 years |
| Gel | 500–800 | 3–5 years |
| AGM | 300–500 | 2–4 years |
🏆 Winner: LiFePO4
👉 Clearly offers the longest cycle life
🔍 Why It Matters for Solar
Solar systems:
- Charge daily
- Discharge daily
👉 Require deep-cycle durability
📉 Cost Impact
Even if lithium costs more upfront:
👉 Total lifetime cost is significantly lower
⚡ Performance Advantage
- Higher efficiency
- Stable voltage
- Deeper discharge
