Junction boxes are used to electrically connect the solar cells inside the solar panel. They represent the connection point between the solar cells and the external wiring that carries the generated power to an inverter or battery. The quality of junction boxes is crucial to the longevity and efficiency of solar panels. They must be resistant to weather, high temperatures, and moisture to ensure reliable operation over time.
