1 Brendan Bossidy

2  Converts light directly to electricity  Made of monocrystalline silicon  Solar energy panel will produce 3,285 kWh in a year

3  Creation of electric current in a material on exposure to light (silicon)  Electrons are transferred between different bands within the material, resulting in the buildup of voltage between two electrodes

4

5  Off-Grid Energy  Large Scale Energy Production

6  Sunshine is only fuel, renewable and local resource  No waste product, no emissions  Quiet and unobtrusive systems  Can utilize empty space on roofs  Low maintenance  Can be constructed to fit any needs  Low environmental impact, chemical easily controlled

7  Toxic chemicals such as cadmium and arsenic used in process, minor usage and impact  High cost to manufacture a PV device  Variable energy source, dependent on the sun  Requires batteries to store energy, batteries must be changed periodically over years

8  Very little  No emissions or waste product  Harmful chemical used in small amounts, easily controlled through recycling

9  Produced and used in year round sunny countries such as California, United States sun belt, and the Mid West  Used in developed countries around the globe that intake a lot of yearly sunlight (Japan, China, Germany)  Little market in developing countries, very expensive now but hope for future

10

11  Can replace coal burning or nuclear power plants when used to create off-grid or large scale energy

12  In US, $2.43/watt, well below nuclear power  Large scale is $1.00/watt  Low maintenance once constructed  Last for several years without battery change, panels last for longer  $5,500 to $22,500 for 0.5kW - 3kW residential PV systems initial cost
