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|
