-You might be wondering what solar power is. Well solar power is radiation created by the nuclear reaction in the sun. Sunlight contains photons which get absorbed by the silicon in the photovoltaic cells which then dislodges the electrons in the semiconductor, then the electrons move to the surface and can be harnessed.

- Photovoltaic devices are: Individual cells that are grouped together and put into arrays of numerous panels. They are made of glass and semi-conductors, which are expensive to make.
