Sealant Stain
Sealant Stain
Cause of Defect: Rain and Moisture
Consequence: If no action is taken, the dirt held by the sealant will eventually be dislodged and carried downward forming stain streaks on the solar panel. Apart from causing the facade to lose its aesthetical value, the stain will shade the solar panels. Hence, it will compromise the optimal performance of the solar panels.
