Solar PV systems generate electricity by absorbing sunlight and using that light energy to create an electrical current. There are many photovoltaic cells within a single solar module, and the current created by all of the cells together adds up to enough electricity to help power your home.
Solar power converts energy from the Sun into electrical energy. One way to do this is with photovoltaic materials. These can be used to create an electric current when they’re exposed to light. This is called the photovoltaic effect. Photovoltaic cells or solar cells can do this.
The working principle of a photovoltaic (PV) cell involves the conversion of sunlight into electricity through the photovoltaic effect.
