Presentation Transcript

  1. Solar Power • Andric Stephens, Gian Kim, Connor Bradley, and • Jack Bley

  2. How Solar works • The current solar cell composes silicon layers • They are engineered to be positive and negative • The light energy excited electrons making them jump in the space available. Magnetic properties of each electron pushes them on their side.

  3. Why Solar? • Solar energy is a renewable resource, useful for people and the environment. • Expensive but have a seen a consistent drop in prices over the last three decades. • Can be used around the world in areas with sufficient sunlight.

  4. Solar’s Shortcomings • It's intermittent. Solar energy is only available when the sun is shining. • It's low efficiency. It requires large areas of land. • It's not completely free of environmental impact. Ultrapure polysilicon is now scarce.

  5. Solars affect’s • Land • Water • Hazardous waste • Climate change
