I remember there was this science barge that had a solar panel that passively tracked the sun by being mounted on a metal tube that had some gas in it that expanded and somehow tilted the panel more towards the sun.

I wonder how much more accurate your system is and whether the tradeoff is worth the added expense of a motor + the additional maintenance cost of moving parts.

I wonder why solar farms don't use active tracking, is that added maintenance + equipment cost just not worth it?
