How energy is produced from the sun
1.5 billion people worldwide live without access to electricity. For people without access to an electrical grid, solar energy is the most cost-effective source of electricity as it provides clean energy to select regions and creates new opportunities.

One can consume solar energy or feed into a public power grid. With a battery storage excess generated electricity can be stored. See how it works:
