Mounting Components

•  Ground Mount – Fixed ✔ – Tracking

•  Single axis •  Multi axis

•  Roof Mount ✔ – Flat (many options) – Tilt (many options)


Ground Mount


Fixed Ground Mount


Mounting Code Compliances •  Design Loads (ASCE7-05)( American

Society of Civil Engineers) •  IBC (international Bldg Code)

•  Types of Load: – Wind sheer calculation – Dead – Snow – Seismic load


Wind

•  Exposure category •  Basic Wind speed (mph) •  Height (ft)


Wind Exposure Category •  B: urban & suburban areas, wooded areas,

terrain with closely spaced obstructions having size of single family dwellings

•  C: Open terrain with scattered obstruction having heights less that 30 ft

•  D: Flat unobstructed areas outside hurricane prone regions.


PV Rail Spans & point loads

•  Determine Design wind Loads •  Select Rail Type & Span •  Determine Point Loads

– Load (lb per sq-ft) – Distributed Load (lb per linear foot) – Point Load (lb)


Data Needed •  Basic Wind Speed •  Building Height •  Effective Wind Area (sf) = minimum total continuous

area of modules being installed •  Roof Zone •  Roof Zone Set Back Length •  Roof Pitch •  Exposure Category •  Least of Building Length or Width •  Topographic Factor


Material Selection •  Many Options are available •  Examples include but not limited to:

– Unirac – Professional Solar – Conergy – Sharp SRS – Quickmount – Thompson Technologies – Etc.


Material Selection •  Use Racking part specifically designed for

Solar (avoid homemade racking) •  Use UL listed material for Grounding lugs •  Use water tight conduit couplings,

Junction and combiner boxes •  Use appropriate wiring- USE-2/RHW

– High temp, wet, inside conduit
