Inspecting Solar Systems: A Seminar for Code Officials, Electric Utilities and Contractors Dave Click, Florida Solar Energy Center (Cocoa, FL)January 26, 2009
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
Afternoon Agenda • Photovoltaic Systems and Applications • Photovoltaic Components and System Configurations • Permitting and Inspection of Photovoltaic Systems • Inspector Guidelines for PV Systems • Inspection Checklist
Principal Elements of a Photovoltaic (PV) System use inversion (AC) & conditioning energy source distribution conversion (DC) electric utility storage
Types of PV Systems • Utility-interactive (or grid-connected, or grid-tied) PV systems • Stand-alone PV systems
Inverter PV Array Service Panel Distribution System Loads in Home A Simple Grid-Tied Photovoltaic System
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
Side-by-Side Tests Finding the efficiency limits Standard vs. Best Available

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
