Photovoltaics (PV) can be defined as the conversion of light into electricity. This is achieved through semiconducting materials that exhibit a photovoltaic effect. A photovoltaic array, which is also known as a solar array, is a linked collection of solar modules.

How does a solar combiner box work?

In order to generate enough power to adequately meet the needs of a home or business, these modules must be linked together in order to form an array.

In a large solar photovoltaic array, multiple solar modules are connected in a string. This excels the voltage levels to make them ideal for the inverter. Several strings of solar modules are then combined together. This multiplies the string output currents to greater levels for input into the inverter.

Solar photovoltaic array combiners (solar panel combiner boxes, or DC combiner box, PV combiner box) are frequently used to connect several solar panels (or strings of panels) to a single bus. They’re essentially junction boxes that are specifically designed for the wiring types seen in PV systems.
