  • 1 PROPRIETARY & CONFIDENTIAL CONTROLLED DOCUMENT REF: SIS-UNIRAC-RACKING-BASICS-REV-2
  • Racking Basics This is an introduction to Unirac’s PV Racking Systems Other presentations we offer include: • Unirac Attachment Options • Unirac SolarMount, RapidRac, CLICKSYS, ISYS, ULA • Array Tilt & Ground Cover Ratio (mutual shading) Optimization • Working Safely with PV Systems • Off-Grid, Grid-Tie, & Grid-Interactive Systems IOM • Other training programs 2 PROPRIETARY & CONFIDENTIAL CONTROLLED DOCUMENT REF: SIS-UNIRAC-RACKING-BASICS-REV-2
  • Outline • Safety First y • Racking Fundamentals • Basic Terminology • Pole Mount O Options • Racking Options • Racking Design Pre Requisites Pre-Requisites 3 PROPRIETARY & CONFIDENTIAL CONTROLLED DOCUMENT REF: SIS-UNIRAC-RACKING-BASICS-REV-2 View slide
  • Safety First • Safety is the responsibility of every employee • Safety is a full-time job • Never work alone on a PV system • Professional tools are a must • Professional equipment training is a must • Know your system before working on it • All circuits must be considered live at all times • Weather / Mechanical / Electrical Hazards pose very serious risks • Adhere to local & international safety codes • Severe injury or even death may result from improper handling 4 PROPRIETARY & CONFIDENTIAL CONTROLLED DOCUMENT REF: SIS-UNIRAC-RACKING-BASICS-REV-2 View slide
