How Commercial Solar Panels Work

Every commercial solar system works by turning sunlight into usable electricity, and it all starts with the solar panels. These panels are made up of silicon cells that react when the sun's rays hit them, triggering the photovoltaic effect. As the light hits the surface, it sets off a reaction that causes electrons to move, which creates an electric current. This process is called the photovoltaic effect, and it's what makes solar energy possible in any PV system.

A solar array, consisting of multiple interconnected panels, is responsible for capturing and converting solar energy for the building.

A typical commercial solar installation comprises three key components:

• Solar Panels: These are the most visible parts of the system and do the important job of capturing sunlight. Inside each panel are silicon cells that convert sunlight into direct current (DC) electricity.
• Inverters: Since most buildings run on alternating current (AC), the system needs inverters to make that switch. Inverters take the DC electricity from the panels and convert it into AC, making the energy usable for lighting, equipment, and everything else your business runs on.
• Energy Storage Systems: Battery storage is becoming more common in commercial solar systems. These systems store any excess energy your panels generate during the day, so you can use it later, like during the night or peak hours.
