Interesting. Thanks.

Of concern was

  ...  UV stable encapsulants, ...

That is an issue but not the main one.
Few, including some people who write learned papers and address
conferences, seem to appreciate what a PV cell encapsulant needs to
do.
The need for UV resistance is a given but the most important aspects
are low modulus, low water content, tight void free adherence to cell
surface and lack of corrosive breakdown products in the encapsulant
long term.

Most people looking for an alternative encapsulant to industry
standard EVA tend to target the wrong things, and many who use EVA do
not understand that all EVA's are not created equal and that it
matters.
Chinese manufacturers who care tend to use German manufactured EVA.
But I spoke to a keen and competent Chinese PV panel maker this week
and he had no conception of using anythin other thanChinese generic
EVA.

The sort of problems that occur woldl mostly be in the 10-20 year time
span - Only of relevance once you've h=3Dgot the general process right.
