Monocrystalline vs Polycrystalline Solar Panels
In 2026, monocrystalline panels dominate the market at 98%+ share. Polycrystalline is being phased out due to lower efficiency. But when should you still consider poly?
| Metric | Monocrystalline | Polycrystalline |
|---|---|---|
| Efficiency | 20-25% | 15-17% |
| Appearance | Dark/black | Blue specked |
| Cost | Lower now | Previously cheaper |
| Space Efficiency | Excellent | Average |
| Temperature Performance | Better | Average |
| Low-light Performance | Better | Average |
| Lifespan | 30+ years | 25 years |
| Market Share 2026 | 98%+ | <2% |

Expert Verdict
Monocrystalline is the clear winner in 2026. It's now cheaper per watt, more efficient, and future-proof. Only reason to consider polycrystalline: legacy project replacement or niche applications.
