2.1FireRating
ThemodulefireratingisType29perUL1703,2013edition.Firerating
classificationforanyPVsystemusingUL1703:2013canonlyestablishafirerating
incombinationwiththemountingsystemratingsnormallyfoundinthemounting
systeminstallationinstructions.
3.0 ElectricalCharacteristics
ElectricalcharacteristicsofthemodulesaredescribedinTable1below.Rated
electricalcharacteristicsarewithin10percentofmeasuredvaluesatStandard
TestConditionsof:1000W/m2,25°Ccelltemperatureandsolarspectral
irradianceperIEC60904‐3orirradiationof(airmass)AM1.5global(G)spectrum.
Eachmodulecontainsthreebypassdiodes.Themaximumseriesfuseratingis
25A.
Undernormalconditions,aphotovoltaicmodulemayexperienceconditionsthat
producemorecurrentand/orvoltagethanreportedatStandardTestConditions.
Accordingly,thevaluesofISCandVOCmarkedonULListedmodulesshould
alwaysbemultipliedbyafactorof1.25whendeterminingcomponentvoltage
ratings,conductorcapacities,fusesizesandsizeofcontrolsconnectedtothe
moduleoutput.RefertoSection690‐8oftheNECforanadditional1.25Safety
factorwhichmaybeapplicable.
DANGER!Moduleinterconnectioncablespassdirectcurrent(dc)and
aresourcesofvoltagewhenthemoduleisunderloadandwhenitis
exposedtolight.Directcurrentcanarcacrossgapsandmaycause
injuryordeathifimproperconnectionordisconnectionismade;or
ifcontactismadewithmoduleleadsthatarefrayedortorn.Donot
connectordisconnectmoduleswhenacurrentsourceisenergizing
theconductors.Modulesmaycontainhighvoltagewhen
interconnectedwithothermodules.
IMPORTANT!Pleasereadtheseinstructionsintheirentiretybefore

4.0 ElectricalConnectionsandSystemMonitoring
Modulesmaybeconnectedinseriesand/orparalleltoachievethedesired
electricaloutputaslongasoptimumdesignparametersareachievedcertain
conditionsaremet.Pleaseuseonlythesametypeofmodulesinacombined
sourcecircuit.Donotmixthemoduleswithdifferentnameplateswithout
authorizationbyMaxeon.

Evenifallowedbylocalregulation,PlugandSocketconnectorsmatedtogetherin
aPVsystemmustbeofthesametype(model,rating)fromthesame
manufactureri.e.aplugconnectorfromonemanufacturerandasocket
connectorfromanothermanufacturer,orviceversa,shallnotbeusedtomakea
connection.

Maxeonrecommendsaconservativeminimumbendingradius(R)5xcable
diametermustbemaintainedandmustnotbebentonthedirectexitofthe
connectororjunctionbox.Avoidexposureofelectricalconnectionstodirect
sunlightanddonotplacetheconnectorinalocationwherewatercouldeasily
accumulate.Installersmustrefertoconnectormanufacturer’sinstructionfor
furtherinstallationandconnectionrequirements.
Connectorsarefactoryassembledwithintentionalgapsbetweenthecablenut
andthebodyoftheconnector.Donotretightenmoduleconnectornutsasthis
mayleadtostresscrackingoftheconnectorassemblyandwillvoidthewarranty.

4.1EquipmentGrounding
Toreducethepossibilityofelectricalshock,groundtheframeofthemoduleor
arrayperNECbeforewiringthecircuit.Inordertoinstallinaccordancewiththeir

5.0 ModuleMounting
TheMaxeonLimitedWarrantyforPVModulesiscontingentuponmodulesbeing
mountedinaccordancewiththerequirementsdescribedinthissection.

5.1SiteConsiderations
Maxeonmodulesshouldonlybemountedinlocationsthatmeetthefollowing
requirements:

OperatingTemperature:AllMaxeonmodulesmustonlybemountedin
environmentsthatensuretheywilloperatewithinthefollowingtemperatures:

OperatingTemperaturerange(ambient)‐40°Cto+85°C
‐40°Fto+185°F

Adequateventilationshouldbeprovidedbehindorunderneaththemodules,
especiallyinhotenvironments.

Shading:Modulesshouldbeinstalledsothatpermanentshadingofcellsis
avoidedandpartialshadingthatmayoccurduringcertaintimesofthedayor
yearisminimized. Permanentshadingisdefinedasshadethatiscastoverthe
sameposition(ofconstantarea)ofthesolarmodulethroughoutthegeneration
hoursoftheday.
Shadingmayinduceincertaincasesstrongenergyproductionreduction,evenin
caseofsmallshadingandshouldbeavoidasmuchaspossible,especiallyatmid‐
daywhentheproductionismaximum.

DesignStrength:Maxeonmodulesaredesignedtomeetapositive(downward)
and/ornegative(upward)withstandingtestpressurewhenmountedasperthe
guidelinesinSection5.2andconfigurationsinAppendix.Testloadsarefor
informationpurposesonly;designloadsshouldbeconsideredfortheproject
design.

Whenmountingmodulesinsnowproneorhighwindenvironments,specialcare
shouldbetakentomountthemodulesinamannerthatprovidessufficient
designstrengthwhilemeetinglocalcoderequirements.

ExcludedOperatingEnvironments
CertainoperatingenvironmentsarenotrecommendedforMaxeonmodules,and
areexcludedfromtheMaxeonLimitedWarranty.
Modulesaredesignedforamaximumaltitudeof2000m.
NoMaxeonmoduleshouldbemountedatasitewhereitmaybesubjectto
directcontactwithsaltwater,orotheraggressiveenvironment.
Modulesshouldnotbeinstallednearflammableliquids,gases,orlocationswith
hazardousmaterials;ormovingvehiclesofanytype.

PerformanceSeriesMountingOrientation
CommercialPerformanceSeries(P‐Series)modulesaredesignedtoperform
betterifinstalledinlandscapeorientation.Inlandscapeorientation,P‐series

5.2MountingConfigurations
Modulesintegratedintoormountedoveraroofingsystemmustbemounted
overafire‐resistantroofcoveringratedfortheapplication.Modulesmaybe
mountedatanyangle,fromhorizontaltovertical.Toreducesoiling,modules
shouldbemountedataminimumof5degrees.

Specificinformationonmoduledimensionsandthelocationofmountingand
groundingholesisprovidedinAppendix.Thesysteminstallerisresponsiblefor
thedeterminationoflocation‐specificloadrequirements.

ItshouldbenotedthatwatertightnessisnotensuredbyMaxeon,therefore,if
watermanagementisrequired,themountingsystemshouldbedesigned
accordingly.

ThemoduleisonlyCSAListedforusewhenitsfactoryframeisfullyintact.Do
notremoveoralterthemoduleframe,anddonotcreateadditionalmounting
holesbecausedoingsomaycompromisetheintegrityoftheframe.
Modulesmaybemountedusingthefollowingmethodsonly:
1) FrameHoles:Securethemoduletothestructureusingthefactory
mountingholes.Four1/4″stainlesssteelbolts,withnuts,washers,andlock
washersarerecommendedpermodule;tightenedtoamin.torqueof10in‐
lb.Thismethodhasbeencertifiedbyathird‐partyorganizationaccordingto
UL1703.Forframeholemounting,modulesmustbesecuredusingthe
holesshowninAppendix.
2) Clamps:Mountthemodulewiththeoppositeclampsonthelongerand/or
shortersidesofthemodule.Installersshouldensuretheclampsareof
sufficientstrengthtoallowforthemaximumdesignpressureofthe
module.ClampsarenotprovidedbyMaxeon.Clampsthatsecuretothetop
oftheframemustnotdeformthetopflange.Clampsmustapplyforce
collinearwiththe‘wall’ofthe
moduleframeandnotonlytothe
topflange.Clampsorinstallation
proceduresthatputexcessive
forceonthetopflangewill
deformtheframe,voidthe
modulewarrantyandriskglass
breakage.Figure1aillustrates
locationsfortopframeclamp
force.Whenclampingtothe
moduleframe,torqueshouldneverexceed132in‐lbs(15Nm)toreduce
chancesofframedeformationand/orglassbreakage.Iftheclamp
manufacturerrecommendsaspecifictorquevaluewhichislowerthan132
in‐lbs(15Nm),theinstallershouldusetheclampmanufacturer’storque
value.Iftheclampmanufacturerrecommendsaspecifictorquevalue
whichishigherthan132in‐lbs(15Nm),theinstallershouldcontactthe
clampmanufacturerforacceptanceofthe132in‐lbs(15Nm)maximum
torquevalueortofindalternativeclamps.Acalibratedtorquewrenchmust
beused.Mountingsystemsshouldbeevaluatedforcompatibilitybefore
installingspeciallywhenthesystemisnotusingClamps.

Minimumclampwidthallowanceis≥35mm,andforcornerclampingthe
minimumclampwidthis:≥50mm.Clampsshouldnotbeincontactwiththe
frontglassandclampsshouldnotdeformtheframe.

Clampswithgroundingfeaturessuchasteeth,pinsthatpenetratethe
ionizationoftheframeareknowntodeformtheframeandbreakthe
moduleglass.Alltheclampswithgroundingfeaturesshouldbeusedatthe
installer/customer’sownrisk.

5.3GroundMountApplicationsforBifacialmodules
Variousenvironmentalandinstallationparametersaffectbifacialgain.Albedoisa
measureoftheamountoflightreflectedfromthegroundsurface.Ahigher
albedofactorwillincreaseirradianceonthebacksideandresultinhigherbifacial
gainofthemodule.Thesurfaceconditions,monthoftheyear,timeofday,GHI
andDNIbothinfluencetheamountofincidentrearsideirradiance.

Maxeonrecommendstocheckwithsolarmodulemountinghardwaresupplierin
ordertodeterminetheStructureShadingfactorofyourparticularinstallation.
TheStructureShadingFactorvarieswithrackingsystemdesign,irradiance,
albedoandheightofmoduleinstallationabovegroundandhasanoverallimpact
ontherearsideirradiancemismatch.
TheRearsidemismatchlossesareproportionaltothealbedo,heightofthe
modulesabovegroundandstructureshadingfactor.Theirradiancenon‐
uniformityontherearsideresultsinmismatchgenerallyasthealbedoincreases
andinstallationheightofthemodulesarelowertotheground.

5.4RooftopApplicationsforBifacialmodules
Bifacialmodulesusedirect,reflectedordiffusesunlightattherearsideto
generateadditionalpower.Therefore,itisrecommendedtousebifacialmodules
installedonflatroofapplications.

Inordertomaximizethebifacialgainattherooftopapplicationsthefollowing
parameterslistedbelowshouldbeconsidered:
SurfaceAlbedo
RoofIntegrity
ModuleTiltAngle
ModuleElevation
StructuralBacksideShading

Thebifacialmodulescanbemountedbothlandscapeorportraitorientationas
showninAppendixsection.
Wheninstallingabifacialmoduleonaroof,ensurethattheroofconstructionand
thestructuralloadcalculationsofthebuildingaresuitable.
Bifacialgaintendstobemosteffectivewithahighertiltangle.
Asthetiltangleandthemoduleelevationfromtheunderlyingsurfaceincreases,
morereflectedlightanddiffuselightcanbecapturedbythemodule.
Themountingrailsshallbedesignedtolimittherearsideshadingasmuchas
possible.

5.5BifacialElectricalConsiderations
Theoverallelectricalbifacialgainisdeterminedbythecombinationofsurface
albedo,irradiance,moduletiltangle,shadinglossesfromtherearside,rearside
mismatchandmoduleelevationaboveground.PleaserefertotheMaxeon
datasheetfortheelectricaloutputswithrespecttotheoverallbifacialgain.
Pleaseutilizeasuitableperformancesoftwarepackagetosimulatetheoverall
bifacialgain

5.6HandlingofModulesduringInstallation
Donotplacemodulesfaceforwardindirectcontactwithabrasivesurfaceslike
roofs,driveways,woodenpallets,railings,stuccowalls,etc…
Themodulefrontsurfaceglassissensitivetooilsandabrasivesurfaces,which
mayleadtoscratchesandirregularsoiling.
Duringstorage,modulesneedtobeprotectedfromrainoranykindsofliquids.
Requiredstoragetemperatureisbetween10°Cto40°Cinadryenvironment
(humiditybetween30to80%).Donotstoremodulesoutdoortoavoidmoisture
andwetconditions.
Modulesthatfeatureantireflectivecoatedglassarepronetovisiblefingerprint
marksiftouchedonthefrontglasssurface.Maxeonrecommendshanding
moduleswithanti‐reflectiveglasswithgloves(noleathergloves)orlimiting
touchingofthefrontsurface.Anyfingerprintmarksresultingfrominstallation
willnaturallydisappearovertimeorcanbereducedbyfollowingthewashing
guidelinesinSection6.0below.Anymodulecoverage(coloredplastictarpsor
similar)duringinstallationcanleadtopermanentfrontglassdiscolorationandis
notrecommended.Theuseofvacuumliftingpadscancausepermanentmarks
onthefrontglass.Neverliftormovethemoduleusingthecablesorthejunction
boxunderany‐circumstances.
Systemenergizationandshutdownproceduresneedtobefollowedbasedon
respectiveNationalguidelinesandlocalregulations.Safesiteoperational
practicesmustbeadheredbeforeenergizingthePVsystem(e.g.electrical
continuity,avoidingdirectcontactwithelectrical/framingequipment,wearing
safetyPPE,etc.).Systemshouldbeelectricallydisconnectedduringmaintenance,
upgrades,andmodificationworkswhichcanaffecttheoperationofPVsystem.

6.0MaintenanceandCleaning
TrainedMaxeondealerortrainedMaxeonsupportpersonnelshouldinspectall
modulesannuallyforsafeelectricalconnections,soundmechanicalconnections,
andfreedomfromcorrosion.
Periodiccleaningofmoduleglasshasresultedinimprovedperformancelevels,
especiallyinregionswithlowlevelsofannualprecipitation;thereforeMaxeon
recommendsperiodiccleaningofthemodules.
Tocleanamodule,washitsglasssurfacewithpotable,non‐heatedwater.
NormalwaterpressureisadequatewhencleaningtheARglass.Some
