Power Optimizers

The solar panel Power optimizers offer many of the same benefits as micro-inverters, but tend to be slightly less expensive. The solar module optimizers are often considered a compromise between more expensive micro-inverters and the standard string inverter.

How a Solar Power Optimizers Work

Like micro-inverters, theoptimizers are located at each panel, usually integrated into the panels themselves. However, instead of converting the DC electricity to AC electricity at the panel site, they “condition” the DC electricity and send it to a string inverter. This approach results in higher system efficiency than a string inverter alone.

Similar to micro-inverters, power optimizers reduce the impact of panel shading on system performance, and also offer panel performance monitoring. Systems that use optimizers are typically more affordable than those that use micro-inverters.
