Solar panels are devices designed to convert sunlight into usable electrical energy. They exist as part of a broader effort to generate power using renewable energy sources rather than relying solely on fossil fuels. Solar panel technology is based on photovoltaic cells, which produce electricity when exposed to sunlight.
The concept of harnessing solar energy has existed for over a century, but practical solar panels became more widespread as technology improved and global energy needs increased. As populations grew and electricity demand expanded, traditional power generation methods faced challenges related to fuel availability, emissions, and environmental impact. Solar panels emerged as a response to these challenges by offering a clean and sustainable energy alternative.
Today, solar panels are used in residential buildings, commercial facilities, agricultural settings, and large-scale power plants. Learning about solar panels helps explain how sunlight can be transformed into electricity and how renewable energy fits into modern power systems.
