Solar power panel is able to function using the solar energy which is derived from the sun. Every solar power panel contains many different silicon cells or solar cells which the are building blocks of solar panels.
Solar batteries are the arteries of any efficient solar panel system. They store energy produced by sun and solar panels allowing the energy to be used as needed through an inverter. Some require a battery back up (or bank) and others are directly wired from solar. Solar energy is derived from the sun.
