What defines an AC module?

An AC module is specifically designed to produce alternating current (AC) output, which means it has integrated electronics that convert the direct current (DC) produced by the solar cells into AC. This design helps streamline installation and can enhance efficiency by providing a plug-and-play solution for connecting to the electrical grid or an inverter.

The distinction of being tested for AC output is crucial, as it ensures that the module meets safety and performance standards for use as an AC power source. Unlike regular solar panels that produce only DC electricity, AC modules eliminate the need for separate inverters at the point of generation, making them an attractive option for many solar applications.

While other options may describe various types of solar products, they do not capture the specific functionality and testing required for a module designated as an AC module. A module producing only DC output or one that combines AC and DC outputs does not embody the defining characteristics of an AC module. Similarly, modules equipped with battery storage systems are not inherently classified as AC modules unless they also provide AC output.
