Solar micro inverters are compact units that attach directly to each solar module to make the entire solar power system more productive, reliable, and competent than a system with a central "string" inverter. Solar micro inverters operate at an overall efficiency of more than 96%, converting power at the module level instead of at the array level. This allows micro inverter PV systems to generate up to 16% more energy yield when compared to a string inverter.
Micro inverters are particularly good at reducing shading problems on solar panels. A common issue with many rooftops, shading from overhanging trees or nearby buildings can dramatically reduce a PV system's power production. In fact, just 9% shade can influence up to 54% of the total system's output with a string inverter. Micro inverters significantly reduce this power loss by managing each PV module individually.Read more +

An inverter is an essential component of any solar energy system, converting direct current (DC) electricity from the solar panels into alternating current (AC) electricity used for your home's appliances. Traditionally, solar systems have utilized a single centralized "string" inverter. However, micro inverters now offer an extremely appealing alternative.
Typically, a solar micro inverter will be connected to each module (panel). Each micro inverter works independently of the others in the system, maximizing efficiency.
There is a single point of failure in a system with a traditional central string inverter. This means that even a simple issue with the inverter will halt solar production completely, potentially causing a loss of power. In contrast, placing one micro inverter per module provides a highly reliable power optimizer and source of solar output. If one of the micro inverters fails, the rest continue to operate.
In addition, using micro inverters can be an intelligent way to avoid reduced production due to sunlight obstructions. From cloudy days and snow to dirt and debris, obstructions on your solar panels can be expected from time to time. However, micro inverters allow each solar panel to operate independently (versus limiting the production to the weakest solar module like a central string inverter would).
Finally, micro inverters offer an individual solar panel performance monitoring capability you might not have even considered. You'll gain the ability to compare the performance of each panel versus only having access to the performance of the system as a whole. This can be a significant benefit when it comes time to service equipment because you can rapidly pinpoint a single panel's (or micro inverter's) failure without diagnosing the entire system.
Micro inverters can be utilized with virtually any setup, though there are specific scenarios in which this option is most beneficial. You may want to consider solar micro inverters vs. a centralized string inverter if:
