"Sunlight is made up of tiny packets called photons. Every minute enough of this 

energy reaches the world to meet the world's energy demand for the whole world. 

Photoelectric panels consists of many solar cells, these are made of materials 

like silicon, one of the most common elements on earth. The individual cell 

is designed with a positive and a negative layer to create an electric field, 

just like in a battery. As photons are absorbed in the cell, their energy  

causes electrons to become free, the electrons move toward the bottom of the 

cell, and exit through the connecting wire. The flow of photons is what we 

call electricity. By combining solar cells and photovolataic panels, we can 

produce just the right amount of electricity to preform a specific job,  no 

matter how large or small."
