Solar power

  1. 1. Andres VargasTEM 194
  2. 2.  The Practice of capturing sunlight and converting it into useable energy Use of Photovoltaic (PV) devices is most common form often used to power houses, buildings, cars etc Solar Electric Power Plants are used to power plants that produce electricity - Mirrors focus heat - Steam produced by solar heating
  3. 3.  It has been said that one solar flare contains enough energy to power the entire Earth for 1 million years! Less dependence on Fossil Fuels and Lower green house gases Natural Disaster proof - NO threat of catastrophic loss of power grid Accessible everywhere, even in remote areas of the World Cost Efficient and affordable form of renewable energy - Ability to pay for itself over the long run
  4. 4.  1876 - William Adams writes a book called A Substitute for fuel in Tropical Countries - Talked in depth about the use of solar energy to replace traditional engine consumption 1878 – William Adams constructs a Solar Powered Steam engine that is 5 times more powerful than any other steam engine at the time. - Concept from this engine is still used in solar towers today
  5. 5.  1883 – Charles Fritz Develops a solar cell with a conversion rate of 2% 1905 – Aubrey Eneas forms The Solar Energy Co. and sells the first solar energy system to a man in Mesa, AZ - Company goes under due to destroyed products 1954 – Bell Laboratories discovers silicon as a semiconductor, develops first solar panel - Discovery crucial to modern day solar tech.
  6. 6.  1970 - OPEC oil embargo causes a major spike in the quest for renewable energy sources - Price of solar cells drop to $20 per watt 1991 – Luz Co., A Los Angeles based solar company, who produced 95% of worlds solar electricity closes their doors due to dropping price of fossil fuels - Investors pulled their funds which caused collapse
  7. 7.  Photovoltaic Devices are being used in homes, buildings, cars and more in order to capture sunlight and create useable energy Semiconductor such as silicon is used to construct a photovoltaic panel Electrons released across panel and funneled to external chamber creating DC current Current is turned run through and inverter that converts it to AC current
  8. 8.  Heat from the sun is concentrated on one point in order to produce steam that can power generators Power is magnified by using parabolic mirrors that capture the sunlight and amplify the heat 13 power plants in the United States use solar power
  9. 9.  Today’s solar panels have the ability to operate at up to 22% efficiency as opposed to 6% of the first solar panels 200 megawatts per year are produced by a pv power plant in China Many such Solar Plants produce upwards of 100 MW in the United States One California plant is being construction with a potential 500 MW output
  10. 10.  #1 Solar University in the United States 57 Photovoltaic projects that produce 15.3 megawatts to the 4 campuses Decreased their carbon emission by 16,000 metric tons - Equal to 1500 homes, 3000 cars ASU to add 1.9 megawatts to their total by the end of the year
  11. 11.  24 hour Solar Power Plants that use solar energy at night and even on cloudy days - First such plant being used in Spain today Storing excess solar power in batteries that can be used at times when extra power is needed Leaning towards the use of parabolic mirrors to create heat that will produce steam
  12. 12.  Cost seems to be the limiting factor when it comes to new solar technology Photovoltaic panels can be very expensive especially when constructing a high efficiency panel Researchers are trying to find new ways to create high efficiency panels without raising costs
  13. 13.  People are using solar panels in their homes for electricity ASU and other organizations are using solar panels for the same purpose Solar powered cars could be the future of green transportation - Some cars already have solar powered components Solar heating can be used in various facets
  14. 14.  ASU offers a Masters Degree in Solar Energy Engineering and Commercialization through the Ira A. Fulton School of Engineering Applicants are required to have a bachelors degree in a Science, Engineering, or Mathematics field 30 credit degree that is set up to take 12 months
  15. 15.  Prerequisites- PHY 121, PHY 131 or PHY 150, PHY151- MAT 270, MAT 271, MAT 272- CHM 233, CHM 234 These would be taken along with supplemental labs and the courses leading up to them. Just an example of some of the courses you may have to take.
  16. 16.  ALT 535 - Applied Photovoltaics EEE 591 - Solar Energy MAE 580 - Solar Energy Colloquium HSD 598 - Solar Energy & Public Policy ALT 507 - Evaluation of Photovoltaic and Fuel Cell Systems Supplemental Courses Include: ALT 515, EEE 565, MAE 598, EEE 598, GHP 598, IEE 541
