Step 4Gluing and painting
The purpose of the little PVC pipe cap enclosure is twofold.
One is that it offers some mechanical protection for the solar cell, which is kinda delicate. So the board and wiring are glued in place with epoxy.
The other purpose is to block out light coming from most directions. So I do like the old Stones song suggests, and paint it black.
