Do you have more information? Are they photovoltaic or water panels?

I think they're referring to the white plastic covering the back side of the panel for electrical insulation. No idea why it's white, since making the back side black would help to radiate heat. (I'm going to guess the specific kind of plastic used is white and the pigments used to change the color have undesirable effects in that application.)

If what you are searching for is what was described above, it is commonly referred to as the "Back Sheet".

NiHaoMike: some back sheets are black. The last Canadian Solar modules I ordered are black frame, monocrystalline, with black back sheet. (I'm doing a ground mount with those and wanted to blend into the scenery). I've seen the encapsulant (the clear goo around the cells) change color over time, and turn yellow on panels with white back sheets.
