Solar panels is a more commonly used and broader term referring to the assembled units that harness solar energy. While often used interchangeably with solar PV modules, solar panels can encompass not just photovoltaic (PV) modules that generate electricity, but also solar thermal panels which heat water or air. In the context of electricity generation, solar panels are arrays of interconnected solar cells designed to capture sunlight and convert it into usable electrical power. They are installed on rooftops, ground mounts, or in large-scale solar farms, providing a sustainable and environmentally friendly way to power homes, businesses, and grids. Their increasing efficiency and decreasing costs have made solar panels a mainstream solution for renewable energy generation worldwide.
