Introduction to Solar Panels
Solar panels, also known as photovoltaic panels, are devices that convert sunlight into electricity. They are a key component of solar power systems, which are increasingly becoming a popular and sustainable source of energy around the world. Solar panels are made up of multiple photovoltaic cells, usually made from silicon, that absorb photons from sunlight and release electrons, creating an electric current.
The advantages of solar panels are numerous. They are a clean and renewable energy source, which means they produce no greenhouse gas emissions during operation and help to reduce reliance on fossil fuels. They also offer long - term cost savings as sunlight is free, and once the initial investment in the solar panel system is made, the cost of generating electricity is relatively low. Moreover, solar panels can be installed on various surfaces such as rooftops, making them suitable for both residential and commercial applications.
