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load,asperIEC61215,
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.


Modulesshouldnotbeinstallednearflammableliquids,gases,orlocationswith
hazardousmaterials;ormovingvehiclesofanytype.

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.

Commercialmodules(128cells)frameshavepermanentlyattachedstackingpins
locatedina20mmzoneonthelongsideframeat388‐408mmfromthecorner.
Mountingsystemhardwareusedwithcommercialmodulesmustaccountforthe
presenceofthesestackingpins(seeAppendix).

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.

Inordertopreventwaterfromenteringthejunctionbox,whichcouldpresenta
safetyhazard,modulesshouldbeorientedwiththejunctionboxinthe
uppermostpositionandnotbemountedsuchthatthecellfacesdownward(e.g.
onatrackingstructurethatpositionsthemoduleswiththejunctionboxfacing
skywardduringsleepmode).

ItshouldbenotedthatwatertightnessisnotensuredbyMaxeon,therefore,if
watermanagementisrequired,themountingsystemshouldbedesigned
accordingly.

Clearancebetweenthemoduleframesandstructureorgroundisrequiredto
preventwiringdamageandallowsairtocirculatebehindthemodule.Forall
modulesaminimumof1.5″ofclearancebetweenthemoduleframesandthe
structure(orgrade)isrequired.Therequiredminimumclearancebetween
installedmodulesis1/4″.
Wheninstalledonaroof,themoduleshallbemountedaccordingtothelocaland
regionalbuildingandfiresafetyregulations.Incasethemoduleisinstalledina
roofintegratedPV‐System(BIPV),itshallbemountedoverawatertightandfire‐
resistantunderlaymentratedforsuchapplication.

Modulesmountingsystemsshouldonlybeinstalledonbuildingsthathavebeen
formallyconsideredforstructuralintegrity,andconfirmedtobecapableof
handlingtheadditionalweightedloadoftheModulesandmountingsystems,by
acertifiedbuildingspecialistorengineer.

Mountingsystemsuppliershallmanagethegalvaniccorrosionwhichcanoccur
betweenthealuminumframeoftheModulesandmountingsystemorgrounding
hardwareifsuchdevicesiscomprisedofdissimilarmetals.
Themoduleisonlycertifiedforusewhenitsfactoryframeisfullyintact.Donot
removeoralterthemoduleframe.Creatingadditionalmountingholesor
removingthestackingpinsmaydamagethemoduleandreducethestrengthof
theframe,thereforearenotallowed.UsingmountingClampsorclipswith
additionalgroundingboltsorgroundingmetalsheetscouldbeincompliancewith
thisSafetyandInstallationInstructionsmanualsubjecttoconditionsofSection
4.1
Modulesmaybemountedusingthefollowingmethodsonly:
1) FrameHoles:Securethemoduletothestructureusingthefactory

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,especiallywhenthesystemisnotusingClampsorclip.

Maxeondoesnotrecommendnorendorsetheapplicationonthemodules
ofclampswhich,aspartoftheirgroundingorearthingfunction,haveteeth
orclawfeatureswhichmay,individuallyorcumulatively,causethemodule

Maxeonshallnotbeliableforanydamagesorlosseswhatsoeverarising
fromtheusebytheInstallerofanysuchclampsonitsmodules,and
disclaimsallwarranties,expressorimplied,applicabletothosemodules
shouldtheybedamagedinanywaybysuchclamps.Therefore,theuseof
theabovementionedclampsbytheInstallerisattheInstaller'ssolerisks.

5.2ModuleHandling
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


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
fingerprints,stains,oraccumulationsofdirtontheglassmayberemovedwith
over‐the‐counterglasscleaners(suchasWindex®orequivalent),orwitha3%
soap‐and‐watersolution.Forsmallersystems,wetthemoduleglasswiththe
solution,letitstandforfiveminutes,andthenwetthemagainanduseasoft
spongeorseamlessclothtowipetheglasssurfaceinacircularmotion.Forlarge
systems,wetthemoduleswiththecleaningsolution,letthemstandforfive
minutes,andthenrinsethemwithhigh‐pressurewaterorasoftsqueegee.Do
notuseharshindustrial‐strengthcleaningmaterialssuchasscouringpowder,
steelwool,scrapers,blades,orothersharpinstrumentstocleanthemodule
