3 The Amount of Sunlight We Receive in 1 Hour is Enough to Power the World for a Year Thats 122 PetaWatts OR 122,000,000,000,000 KWHs

4 1300 Watts of Solar Energy per Square Meter Impact the Upper Atmosphere By the Time that Solar Energy Reaches the Ground 300 Watts have been Lost Through Absorption or Reflection by Particles in the Air Thats Gives Us 1000 Watts / Sq Meter to Create Clean Energy

5 NASA Uses Solar Film Panels for Powering Satellites

6 Earlier Solar was Mostly Used for Off- Grid Applications Solar System is Not Connected to the Electric Grid

7 Now Most Solar Systems Installed Are Grid-Tied Solar System Is Connected to the Electric Grid

8 Solar PV Generates Electricity Solar Thermal Utilizes the Suns Heating Properties to Heat a Liquid Hot-water Heater Pool Heating Radiant Floor Systems

9 Germany is the Largest Installed PV Country in the World 40% of Their Energy Comes from Solar Feed-In-Tariff or FIT Only place in U.S. with this type of program is Gainesville, FL More Communities in the U.S. are Considering a FIT

10 Solar Tour - Florida Tampa Bay Area

11 National Renewable Energy Laboratory (NREL) Mapped the United States for Solar Radiation Tampa Bay Area Insolation is 5.4 Which is Only 13 % Less Than U.S. Peaks and Provides Excellent Energy Production U.S. Solar Peak Radiation is Located in the Desert Area of Southwest United States

13 Photoelectric Effect The photoelectric effect is a phenomenon in which electrons are emitted from matter (metals and non- metallic solids, liquids, or gases) after the absorption of energy from electromagnetic radiation such as X-rays or visible light. [1] electronselectromagnetic radiationX-raysvisible light [1] Visible Light is Made Up of Photons They Carry Enough Energy to Cause an Electrical Current to Flow Serway, Raymond A. (1990). Physics for Scientists & Engineers. Saunders. pp ISBN Describes the photoelectric effect as the "emission of photoelectrons from matter", and describes the original usage as the "emission of photoelectrons from metallic surfaces" after the experiments of Milikan, and others.Physics for Scientists & EngineersISBN

14 Two Biggest Countries Manufacturing Solar Panels are Germany and Japan We Start with Silicon Not Silicone – It has Other Uses Like Sealing Up a Leaky Bathtub Or Certain Personal Image Improvement Enhancements

15

16 Start with Silica Sand Most Abundant Mineral in the Earths Crust

17 Mono-Crystalline Most Efficient – as high as 22% Single Seed Crystal Used to Form Entire Ingot Poly-Crystalline High Level Efficiency – 15-18% Slightly Less Expensive than Mono Thin Film Least Efficient – 6-10% Cheapest to Manufacture Uses Ink Printing Method

18 Chemical Process to Purify Into High-Grade Silicon Silicon is Then Heated and Molded Into a Silicon Ingot Silicon Ingot is Then Cut by Diamond Saw or Laser Into Silicon Wafer

19 Wafer is then Transformed into a Solar Cell by Chemical Processing and Addition of Electrical Contacts

20 Solar Cells are then Assembled Together to Form a Solar Panel Solar Cells are then Assembled Together to Form a Solar Panel
