    1. Solar Energy Nici Karris, Megan Koch, Kelli Krage, Heather Lindner, & John Stanek

    2. Doesn’t this car look FAST?!?

    3. Preview Electrical Energy from Solar Power Pros and Cons of Solar Energy Reliability and Efficiency of Solar Energy Pollution Technological Challenges The Major Producers

    4. How do we create electrical energy from solar power? Creating solar power Solar Panels How they are made Solar panel placement PV photoelectric cells

    5. How to make photovoltaic cells Most widely used material for PV cells is Silicon The silicon is “doped” with boron or phosphrous to give it the properties needed to be a PV cell and give up electrons when exposed to light The photons of light are “knock” the elctrons out of the outside bond of the Silicon atom and that is what creates the PV effect.

    6. What are the pros and cons of solar energy? Advantages Free No fuel No pollution Can be used in remote places Handy and efficient Disadvantages Doesn’t work at night Power stations Solar Cells can be expensive Unreliable

    7. How reliable is solar energy? Reliable when the sun is shining Highest reliability factor Strongest in the summer

    8. Does it cause any type of pollution? Solar energy does not cause pollution but it’s by-products and the construction of solar stations cause pollution. Pool heating Water heater Electric systems Calculator

    9. What are the technological challenges to produce electrical energy with solar power? Solar sources are expensive to build Cost more then electricity produced Solar power also has it’s limits

    10. How efficient is solar power at creating electricity? Solar power is renewable Each day more solar energy falls to the earth than the total amount of energy the planet’s 6 billion inhabitants would consume in 27 years. We currently only harness about 1% of this energy

    11. Where in the U.S. is solar power a major producer of electrical energy? Southwestern part of the U.S. produces the largest amount of solar power California, New Mexico, Nevada, & Utah Uneven distribution of the sunlight on earth

    12. Could solar power even be used to supply ALL the energy needs of the US? Enough energy to meet all power needs Find away to properly harness energy Inconsistency of the weather Amount of energy used will rise considerably

    13. Summary Photovoltaic cells convert light directly into electricity Solar power is one of the highest reliability factors of any energy choices When the sun is shining Solar energy does not cause any type of pollution By-products Solar power sources are very expensive to build If harnessed correctly solar power could be more efficient and supply all the power needs The southwestern corner of the U.S. produces the most solar power
