Abound SolarMounting Application NoteAB1-SeriesPage 1 Document #3106761 Rev AEffective 18 May 2010AB1-Series PhotovoltaicModulesMounting Application NoteAbound Solar, Inc.www.abound.comOverviewThe purpose of this application note is to helpguide system designers by providing themechanical requirements for mounting AboundSolar’s AB1-Series of Photovoltaic Modules andsuggesting possibilities for mounting techniques.Abound Solar provides this information only as aminimal starting point, and compliance with theinformation contained herein is not a guaranteeof an approved photovoltaic system.Contents1.0 Safety................................................... 12.0 The AB1 Module .................................. 13.0 Clips ..................................................... 33.1 Approved Clips ................................. 34.0 Racking ................................................ 41.0 SafetyAll instructions should be read and understoodbefore attempting to install, wire, operate, and/ormaintain the AB1 photovoltaic modules. Beaware that metal rails can have sharp edges.Please make sure that your designs allow for thesafe installation of equipment.DANGER: Risk of Electrical ShockPV modules generate DC electricalenergy when exposed to sunlight orother light sources. Contact with electricallyactive parts of the module such as terminalscan result in burns, sparks, and lethal shockwhether the module is connected ordisconnected.Caution: Risk of Broken Glass. Sincethe AB1 Module consists primarily ofglass, the possibility of broken glassexists. Broken glass can be sharp and causeinjury if not handled with protective equipmentsuch as gloves and eyewear.Specifications are subject to change; pleasecontact Abound Solar to ensure that you areutilizing the most current information available.2.0 The AB1 ModuleOverview: Abound Solar modules arecomprised of two sheets of glass that arebonded together. There is a gap between thesetwo pieces of glass. The construction is suchthat there are reinforcing beads within this area,giving the module exceptional strength. Theinterior of this assembly contains thesemiconductor film, which will produce electricitywhen exposed to sunlight. Cables with industrystandard MC4 style connectors provide for theelectrical connections. A junction box is on therear of this module assembly to provide strainrelief to these cables. These are framelessmodules. Each module weighs about 12 kg,which is about 26 pounds. This equates to a roofloading of 3.125 #/SF (15.25 kg/m2).Within Abound AB1 Photovoltaic Modules, theactive cells are oriented along the long axis.This allows the maximum number of modules tobe stacked in series before hitting the voltagelimitation of the inverter, maximizing theobtainable electrical energy from each string.Because of this cell orientation, ‘portrait mode’mounting orientation is desirable to minimize thepossibility of complete shading of any one cell.Engineering CAD models of the AB1 modulesare available; please contact Abound Solar formore details. |
