Solar panels are a type of technology that converts sunlight into electricity. They are made up of photovoltaic cells that absorb the sun's energy and convert it into usable power. Solar panels are an eco-friendly way to generate electricity, as they produce no greenhouse gas emissions. They can be installed on rooftops or in large solar farms, and are becoming increasingly popular as the cost of installation decreases. Solar panels offer a sustainable and renewable source of energy, making them an important component of the clean energy movement.
