Microinverters are rapidly gaining popularity, particularly for residential solar systems. Microinverters tend to be more expensive than string inverters or power optimizers, but their costs are falling as they become more popular.


How Microinverters Work
Microinverters are installed on each individual panel in a solar energy system. They convert the DC electricity from your solar panels into AC electricity on your roof, with no need for a separate central inverter. In many cases the microinverters are integrated into the solar panel itself, but they may also be mounted next to the panel on the mounting system.


One of the major advantages of microinverters is that they cancel out the negative impacts of partial or complete shading. Because the DC-AC electricity conversion takes place at each panel, there is no “bottleneck” when one panel’s production decreases. Microinverters also allow you to monitor the performance of individual solar panels.
