  2. Acknowledgments,Contact Information • GRU • Jerry Ventre & Jim Dunlop, NJATC • John Wiles, NMSU • http://www.nmsu.edu/~tdi/Photovoltaics/PV-Energy.html Dave Click, Research Engineer Florida Solar Energy Center 321.638.1408, daveclick [at] fsec [dot] ucf [dot] edu

  3. Afternoon Agenda • Photovoltaic Systems and Applications • Photovoltaic Components and System Configurations • Permitting and Inspection of Photovoltaic Systems • Inspector Guidelines for PV Systems • Inspection Checklist

  4. Photovoltaic Systems and Applications

  5. Principal Elements of a Photovoltaic (PV) System use inversion (AC) & conditioning energy source distribution conversion (DC) electric utility storage

  6. Types of PV Systems • Utility-interactive (or grid-connected, or grid-tied) PV systems • Stand-alone PV systems

  7. Inverter PV Array Service Panel Distribution System Loads in Home A Simple Grid-Tied Photovoltaic System

  8. Solar Electric, Thermal and Energy Efficiency • An effective and highly marketable combination • Both electric and thermal power produced on site • A giant step toward the zero energy home

  9. Side-by-Side Tests Finding the efficiency limits Standard vs. Best Available

  10. The Potential of PV and Building Technologies

  11. Net Energy Use

  12. Integrating PV Systems and Buildings

  13. Stronger roof for high wind loads Double trusses to support roof components and cladding (i.e., PV array attachments) Manufactured Housing

  14. 53 kW Façade and Roof GlazingLibrary, Mataro, Spain

  15. NIST’s Rooftop Photovoltaic System Size – 35 kW DC (Standard Rating Conditions) Total Installed Cost - $239,945 or $6.86 per DC Watt Installation Date – September 11-14, 2001

  31. The Old and New Frontier

  32. Photovoltaic Systems Overview

  33. Installed Costs for 100 PV Systems in Florida Total Costs Equipment Costs Labor Costs

  34. PV System Strengths and Weaknesses

  35. Myth that Solar Energy Uses too Much Space Lake Mead formed by Hoover Dam has an area of 640 km2. The dam has a capacity of 2,080 MW. If the same area was covered with 15% efficient solar modules, the peak solar output at noon could be at least 60,000 MW! This includes a large margin for DC-AC inverter loss and the spacing between PV array rows

  36. Atlantis Energy Systems BP Solar DayStar Technologies, Inc. Energy Photovoltaics, Inc. Evergreen Solar First Solar GE Energy Kyocera Motech Mitsubishi Electric Q-Cells Schott Solar Sanyo Sharp Solar Solar Energy Corporation Solar Integrated Tech. Solar World (formerly Shell Solar) SunPower Suntech Uni-Solar PV Module Manufacturers

  37. Florida PV Progress Residential: • $4/W incentive (up to $20,000), if money still available • Solar systems exempted from property tax • Net Metering Commercial: • $4/W incentive (up to $100,000), if money still available • Net Metering (up to 2MW) • State buildings to incorporate solar in renovations/new construction http://www.dsireusa.org/ - up to date listing of incentives
