What is solar energy?
Solar energy is energy obtained from the use of electromagnetic radiation from the sun. Solar radiation has been exploited since ancient times using different technologies that have evolved over time.
Today, heat and sunlight can be exploited through photovoltaic panels or thermal collectors, which they transform into electrical or thermal energy.
Solar photovoltaic energy
Photovoltaic solar energy is a type of renewable energy from which electricity is obtained through the rays of the sun. It is captured by metal sheets called photovoltaic cells. These cells are coated with a material that produces a photoelectric effect, that is, they absorb photons of light and emit electrons that are then captured, producing an electric current.
