What is the difference between string inverters and microinverters?
| Key Metrics | String Inverters | Microinverters |
| Functionality | Converts DC to AC for all solar panels connected in a string | Typically converts DC to AC for each individual or a group of two panels |
| Efficiency | Lower efficiency in partially shaded conditions | More efficient than string inverters, especially in partially shaded conditions |
| Cost | Cheaper | High upfront cost but deliver higher lifetime value |
| Installation | Installation is complex and time consuming | Installation is easier and safer |
| Point of failure | If one inverter in a string has a failure, the entire string will stop producing electricity, leading to larger losses affecting the rest of the system | If a microinverter stops working, then only the panels connected to that microinverter will stop working, without affecting the rest of the system |
