Hi Everyone!
I was cleaning my solar tiles yesterday and noticed this strange pattern on one of the tiles. At first I thought it was bird droppings, but when I looked closer, I realized it was under the glass.
Has anyone seen this before? I don't know what it is and if it means the tile is degraded or bad.
