What is the difference between a power optimizer and a microinverter?
Microinverters make the DC to AC conversion right at each solar panel, unlike power optimizers that aggregate the electricity from your panels and send it to a string inverter. Both systems allow you to monitor the performance of individual solar panels.
What is a micro inverter?
Micro inverters are smaller inverters installed on each solar panel in a system, hence the name “micro.” Each solar panel in a Micro inverter system has its dedicated Micro inverter attached to its back. These Micro inverters convert the DC power generated by the panel directly into AC power at the panel level.
How do string inverters optimize power output?
Without module-level power electronics, string inverters can only optimize power output at the string level, not at the individual panel level. Modern solar inverter and panel technology allows individual panels to continue producing power even if a part of the panel is shaded.
When are microinverters or optimized string inverters necessary?
Microinverters and optimized string inverters are necessary for more complex roofs. They are typically more expensive than string inverters, but offer advantages for certain solar panel installations.
Should I use a power optimizer or a string inverter?
If your roof experiences shade during the day, the panel level optimization afforded by power optimizers often results in higher system efficiency than using a string inverter alone. Similar to microinverters, power optimizers not only reduce the impact of panel shading on system performance, but also offer panel-level performance monitoring.
When are microinverters necessary?
Microinverters and optimized string inverters are typically more expensive than string inverters, but are necessary for more complex roofs. String inverters are the most commonly installed type of inverter worldwide–they're great if your roof is heavily shaded.
