This idea seems like it has a lot of potential. I’m curious about the long-term durability and maintenance needs. Railroad tracks seem like a harsh environment for glass panels to live in.
Solar panels are tougher than cutlery: "Most monocrystalline and polycrystalline solar panels are rated to withstand 25 millimeter (0.98 inches) diameter hail falling at 50 miles per hour"
What a waste of taxpayer dollars. There’s endless amounts of open land to put real solar farms on but no, let’s spend money on this nonsense.
