outputandevenformhotspots.Itisrecommendedthatthesurfaceofthepanelsshouldnot
beobstructedbyanythingwhenthereissunlight.
Thecleaningfrequencydependsonthehowmuchforeignmatteranddebrisaccumulates.
Inmanyinstancesthefrontsubstrategetscleanedwiththerain,andyoucandecreasethe

Pleasedonotcleantheglasswithcleaningagentwhichcontainsacidoralkali.
Toavoidpotentialelectricalshockorburn,pleasecleanthePVpanelsintheearlymorningor

8.2. Visual Inspection of PV Panels
InspectthePVpanelsvisuallytondifthereareappearancedefect,especially:
zIftheglassisbroken;

zChecktheencapsulationoftheconnectorwiththecable.
zEnsurethePVpanelsareuntouchedwithsharpobjects.
