I'm an inexperienced panel fabricator. Previously used 1/8" Plexi not-encapsulated cells with off-grade cells as prototypes but I'm slowly educating myself and want to embark on a larger (1600-3000 watt array) project. I want to either use EVA/EVA/Forget letter backsheet (TPA?) lamination or Sylgard 184. It seems tthat the EVA is more industry standard but I don't know how well the DIY method of fusing with heat gun works. Does anyone have experience, thoughts, advice? Thanks
