Your inverter choice shapes performance, safety and cost. Microinverters (e.g. Enphase) sit under each panel with individual MPPT, while a string inverter manages a whole series of panels from one central unit.
Head-to-Head Comparison
| Feature | Microinverter | String Inverter |
|---|---|---|
| MPPT | Per panel | Per string |
| Shading tolerance | Excellent | Poor (one shaded panel drags the string) |
| Safety | Low DC voltage | High DC voltage |
| Monitoring | Per-panel | System-level |
| Cost | Higher | Lower |
| Scalability | Panel by panel | Per string |
| Best for | Complex / shaded roofs | Simple unshaded roofs |
