The common name for a device that traps solar energy is a "solar panel." Solar panels consist of photovoltaic cells that convert sunlight into electricity through the photovoltaic effect. They are widely used in residential, commercial, and industrial settings to harness renewable energy and reduce reliance on fossil fuels. Solar panels come in various types, including monocrystalline, polycrystalline, and thin-film, each with distinct efficiencies and costs. The adoption of solar panels supports sustainability goals and helps decrease greenhouse gas emissions while providing an alternative energy source for heating, lighting, and powering electrical devices.
