Solar power
firstly, let me teach you an important fact, you may be surprised to listen that sun produces enough energy in a day, which the whole world can use for one year. That's why we call the Sun as Powerhouse or energy house. We know that sun produces energy in the form of light and heat. This energy of the sun is called solar power. We can utilize this energy of the Sun in our daily life, for different purpose.
what is solar power.
solar power is the conversion of solar energy to electrical energy using photovoltaic cells or concentrated solar power. I mean, we use two methods like photovoltaic cells are concentrated solar power to utilize so Solar energy in order to generate electricity.
What is photovoltaic cell?
For example, photovoltaic cell is made up of semiconductor like Silicon or Boron when light fall on this cell electron is ejected.
By this way, billions of electrons are ejected from the photovoltaic cells.Now if we provide conducting path to these photoelectrons electric current is generated. Just by this way, electricity is generated.
to simplify this concept further. We can say that sunlight is the fuel for generation of electricity. Therefore, remember that photovoltaic is Solar cell and converter cell, which converts sunlight to electrical energy Therefore let me teach you two bonus questions.
Does photovoltaic cell store energy.
The answer is, no,
It doesn't store any energy only converts sunlight to electricity. I mean, every day time when sunlight is available, the photovoltaic cell would convert it to electrical energy. In Night time no Electricity is generated by photovoltaic cell due to absence of sunlight. Also, remember that more light means more production of electricity.
Can we store solar energy?
The answer is. Yes, we can store solar energy using electrochemical cell
During daytime the solar energy is stored in electrochemical batteries later,We can utilize this stored, solar energy to provide electricity, and remember that photovoltaic cell is used to convert sunlight to electrical energy, and electrochemical batteries are used to store solar energy.
