What is a string vs micro inverter?

While comparing string vs micro inverter, there are a few main factors you need to keep in mind, these are Efficiency, Size, Warranty, and Price of the inverters. String inverters are becoming a popular alternative over central inverters in small installations generally smaller than 1 MW. String inverters perform well with power optimizers.

What is a string inverter?

A string inverter is the most commonly used type of solar inverter, especially in residential and small commercial systems. It connects multiple solar panels (called a "string") to a single central inverter, which converts the collective DC electricity from the array into usable AC power.

What is a microinverter & how does it work?

A microinverter is a small inverter installed on each individual solar panel, converting DC to AC right at the source. Unlike string inverters, microinverters work independently per panel, which means if one panel is shaded or underperforming, it won’t drag down the output of the others.

Do you need a string inverter or a microinverter?

Microinverters are expendable so if you wanted to add additional panels in the future even if they don’t match the characteristics of the panels you have, you can just add another inverter and can expand your system as much as you want whereas, with string inverters, you do need to keep some types of panels.
