ENGR 312 photovoltaic systems

  1. 1. Photovoltaic Systems ENGR 312 Chris Flynn Wes Grebski
  2. 2. What is a photovoltaic cell? <ul><li>Photovoltaic (PV) cells convert sunlight into electric power. </li></ul>
  3. 3. Development of Photovoltaic Cells <ul><li>1954 – Invented at Bell Labs </li></ul><ul><li>1960 - Handmade until this time </li></ul><ul><li>Cost: $1000/Watt (approximate) </li></ul><ul><li>2010 - Mass production </li></ul><ul><li>Cost: $3/Watt (approximate) </li></ul>
  4. 4. Designing and Sizing PV Systems <ul><li>In designing and sizing a PV system, it is necessary to calculate the predicted annual power distribution. </li></ul><ul><li>National Renewal Energy Laboratory has developed a PV Watts Calculator which determines the energy production and cost saving of grid connected PV energy systems throughout the world. </li></ul><ul><li>http://rredc.nrel.gov/solar/codes_algs/PVWATTS/version1/ </li></ul>
  5. 5. Calculating the Environmental Impact of a PV System <ul><li>The environmental impact of the PV installation can be calculated based on the energy production. </li></ul><ul><li>The calculators for determining the environmental impact are available through </li></ul><ul><li>http://www.epa.gov/cleanenergy/energy-resources/calculator.html </li></ul>
