Inferior plastics are used or if the thermal properties of the plastics are poorly understood so it doesn t melt to exactly the right point or the plastics or the glass are not perfectly clean and compatible or the laminating.
What is lamination solar panel.
Eva films are an essential material used for traditional solar panel lamination.
1 compared to epoxy resin sealed solar panel the costs of pet is a bit higher.
Why we need eva films and how are they integrated into solar pv panels.
As solar panels are exposed and subject to various climatic impact factors the encapsulation of the solar cells through lamination is a crucial step in traditional solar pv module manufacturing.
Solar modules need to convert sunlight to electricity at an acceptable cost throughout their lifetime.
They are then laminated by machine at a temperature of 135 degrees celcius which will melt the encapsulating materials together to form a watertight bond.
This is problematic for a solar panel because it allows air and moisture to creep inside which will cause corrosion and imminent failure.
Delamination will occur if.
To protect solar photovoltaic cells from adverse weather conditions these are laminated embedded between transparent eva films in a vacuum and under heat and compression with the aid of a lamination machine.
Solar panel delamination takes place when the bond between back plastics and the front glass begin to separate.
Photovoltaic laminate pvl photovoltaic laminates can be applied to dimond roofings range of tray products to enable solar power generation including solar rib and can be applied at the time of installation or after the roofing profile has been installed.
Solar panel lamination ensures the longevity of the solar cells of a module as they need to be able to withstand outdoor exposure in all types of climate for periods of 25 years and more.
The pet laminated solar panel is made by placing layers of pet eva solar cell and pcb together.
When such occurs it becomes a problem for the solar panel as it permits air and moisture to find a way into the solar panel thereby causing corrosion and power failure.
