Solar panels work by converting sunlight into electricity. They are made up of photovoltaic (PV) cells, which are sandwiched between layers of semi-conducting material. When sunlight hits the PV cells, it knocks electrons loose from their atoms. These electrons then flow through an electric circuit, creating an electric current.
The amount of electricity that a solar panel can generate depends on the amount of sunlight it receives. Solar panels work best in direct sunlight, but they can also generate electricity on cloudy days.
Solar panels do not need direct sunlight to work. They can also generate electricity from diffused sunlight, which is sunlight that has been scattered by clouds or other objects.
The efficiency of a solar panel is the percentage of sunlight that it can convert into electricity. The efficiency of solar panels has been increasing in recent years, and they are now able to convert about 20% of sunlight into electricity.
Solar panels are a clean and renewable source of energy. They do not produce any emissions, and they can help to reduce our reliance on fossil fuels.
