🔋 Introduction
Choosing the right DOD is one of the most important decisions in solar system design.
👉 It directly affects lifespan and return on investment.
📊 DOD Comparison
| DOD | Pros | Cons |
|---|---|---|
| 50% | Long lifespan | Low usable energy |
| 80% | Balanced | Slight capacity loss |
| 100% | Max energy | Shorter lifespan |
🔍 Key Insight
👉 There is no “one-size-fits-all”
But:
👉 80% DOD is optimal for most systems
⚖️ ROI Perspective
- 100% DOD → more energy today
- 80% DOD → more energy over lifetime
📈 Lifetime Energy Comparison
👉 Lower DOD often delivers more total energy over years
⚡ System Design Recommendation
| System Type | Recommended DOD |
|---|---|
| Off-grid solar | 70–80% |
| Hybrid system | 60–80% |
| Backup system | 30–60% |
💡 Engineering Tip
Combine:
- DOD control
- Smart BMS
- Temperature management
