Solar cell panels are made up of numerous solar cells, usually composed of silicon, a semiconductor material known for its efficiency in converting solar energy into electrical energy. The technology operates on the principle of the photovoltaic effect, where sunlight knocks electrons loose from their atoms, allowing them to flow through the material and generate electricity. This process is not only efficient but also scalable, making solar energy a viable option for various applications, from small residential setups to large-scale solar farms.
