On the back of every solar panel is a small, weatherproof container called the junction box. Its job is to safely house the panel's electrical connections and protect them from debris and weather damage. This area primarily comprises 1. The protective layer, which shields the internal components from environmental elements, 2. . Also known as photovoltaic (PV) cells, solar cells are the heart of a solar panel. They're made from semiconductor materials, typically silicon, that convert sunlight directly into electricity. When sunlight strikes a cell, it excites electrons in the silicon, setting them in motion and creating an. . The wiring within the panels collects energy from this PV process, and an inverter transforms the DC current into alternating current (AC) for immediate or future use.
