String Inverters vs Micro Inverters vs Power Optimizers

The first decision is whether to use micro inverters, an optimizer, or a string inverter for your solar system installation. Read in greater detail in the link below on the main differences between these options based on the most popular brands: SolarEdge Power Optimizers vs Enphase Micro Inverters vs SMA String Inverter


When to Pick String Inverters vs Micro Inverters or Power Optimizers 101:

String inverters are the most cost-effective inverter option available, and the most popular option among solar installations. However, if there is any shading, you would need micro inverters or an optimizer to prevent the shading from affecting the rest of the solar panels. String inverters produce only as much as the weakest link does, so if you have shade falling on one panel, it impacts the output for the entire string.

See video for a quick and simple visual explanation:


Micro inverters and power optimizers are also best when panels are facing different directions. By being installed on each individual panel, you will also be able to monitor production of each individual panel and recognize any issues in production quickly and accurately.

Power optimizers are generally less expensive than micro inverters, but the prices of micro inverters have been going down over time as well. Wondering how much your solar system will cost depending on what you choose?
