Not sure if this was intentional or not, but I noticed that on every new game, if I haven't yet researched interior lighting, and I somehow place a solar panel on nauvis, the interior lighting technology ends up being flagged as researched.
With cross-surface poles, having one surface at nighttime "corrupts" all other surfaces, causing solar panels to break. This is a vanilla bug but the devs don't plan on fixing it. https://forums.factorio.com/viewtopic.php?f=48&t=96830
The technology is researched because if the player somehow gets solar panels early, they need to be usable.
