Butyl adhesive for photovoltaic panels

Should you add a desiccated butyl edge sealant to a PV module?

Learn the benefit of adding a desiccated butyl edge sealant to the photovoltaic (PV) module package by examining the impact of desiccant on moisture breakthrough time and the test results demonstrating adhesion to qualify as a cemented joint. PV module packaging materials have a tough job.

What are SolarGain® solar panel sealants?

SolarGain® Solar Panel Sealants are desiccated butyl/desiccated PIB solar panel sealants designed for use in a wide variety of photovoltaic (PV) modules.

Is ethylene vinyl acetate bad for solar panels?

Solar panel manufacturers often turn to ethylene vinyl acetate (EVA) encapsulants, but Quanex said in a press release that EVA has the potential to generate acid that can decrease solar output due to the corrosiveness of the acid when exposed to moisture over time.

What is PSET adhesive?

PSET is a polyisobutylene butyl rubber adhesive. This adhesive is used to effectively prevent outside moisture or other contamination from having a negative influence on the frameless solar panels. PSET is preferable over tape due to its: Good heat resistance (holds up well in sunlight and high temperatures)

Are crystalline silicon panels sensitive to moisture ingress?

While it is commonly assumed that crystalline silicon panels are not sensitive to moisture ingress over the long term, recent testing by the company has shown SolarGain Edge Sealant’s ability to provide high levels of moisture protection in c-Si panels, extending lifetime power output.

Are ethylene vinyl acetate encapsulants corrosive?

Traditional ethylene vinyl acetate (EVA) encapsulants have the potential to generate acid that can sap a panel of its power, due to the corrosiveness of the acid when exposed to moisture over time.
