EVA Encapsulation Film
EVA encapsulation films are intended to have a very simple function, they are to protect the solar panel electrode. This is accomplished by encapsulating the very fragile electrode top and bottom (surrounding) with a film that is fused to the electrode with heat and pressure. The traditional solar panel is a sandwich made of glass/EVA/electrode/EVA/back panel.
The film must intimately flow into every contour (no voids), be as clear as possible (no yellowing), be sufficiently flexible to handle daily thermal expansion/contraction, be pliable to act as a shock absorber between the glass front panel and the supporting back panel, and do this for a minimum of 25 years.
In order to achieve this, EVA Encapsulation films must have a number of crucial properties when produced. These properties ultimately affect the performance and longevity of the solar panel.
Ensuring these attributes exist from the start can only be achieved when the film is produced on equipment designed and manufactured with these properties incorporated in the design, followed by the use of high quality components, and finally through to the integration of state of the art controls. Anything less will result in a film that does not stand the test of time in the solar panel.
Alpha Marathon's “Alpha Energy” has been engineered to make certain that EVA Encapsulation Films produced meet today's and tomorrow's requirements.
“Alpha Energy” Design Parameters ensures:
- Low gel count
- Processed with a high degree of thermal uniformity to prevent premature cross-linking
- Exceptionally consistent gauge profile
- Minimal shrink characteristics
- Contaminant free film surfaces
- Negligible roll winding deformation
According to some analysts, the market is growing from an installed base of solar modules producing 6 gigawatts a year in 2008 to a projected 34.7 GW/year by 2015.
Let Alpha Marathon partner with you by providing its “Alpha Energy” solution in the production of Encapsulation films.
