Solar panels, also known as photovoltaic (PV) panels, are devices that convert sunlight into electricity. They are made up of solar cells, which are typically made from silicon and are housed in a weatherproof frame. When sunlight hits these cells, they absorb photons, which excite electrons and create an electric current. This current can then be used to power electrical devices or fed into the grid for use by others.

Solar panels are an increasingly popular choice for renewable energy due to their low operating costs, long lifespan, and the fact that they produce clean, sustainable energy. They are commonly used in residential, commercial, and utility-scale applications. With advancements in technology, solar panels are becoming more efficient and affordable, making them a viable option for many looking to reduce their carbon footprint and energy bills.
