I noticed some LONGi panels I bought in 2022 looked different on days with light drizzle and days with morning dew. The water drops don't bead like they do on the other (LONGi, Jinko, & CSI) panels I've used. More recently I noticed they seem to shed snow better as well. The anti-fogging properties is a known feature hydrophilic PV glass as documented in this paper:

When buying panels, I'd like to know if the glass has a hydrophilic or hydrophobic treatment. However I can find no mention of it in manfuacturer datasheets. Any ideas on how I can get this information?
