EVA Sheet encapsulant question
System
Posts: 2,511 admin
Can you just use the EVA Sheet encapsulant with the solar glass only and sandwich the cells between the one sheet of EVA and the glass?

any solder bumps, tab wire or bugs that vary the thickness, will instantly pulverize the cells when the vacuum is applied.Powerfab top of pole PV mount | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

Hey Fabieville
I tried exactly that using a heat gun to melt the EVA and sandwich the cells, using a vacuum pump to suck the cells to the glass. Looked great when I finished, but after several weeks in the sun the EVA separated from the glass. EVA doesn't adhere well enough to glass.

The encapsulant that name sylgard 184 that you pour on the cells. Do you think that the container of approx. 500ml would be enough to cover (36) 6"X6" Cells?
Here is the link for the sylgard 184:
