Really? I'm seriously asking, because I thought solar farms already had automated ways of cleaning off the panels, surely an automated way to cover the panels wouldn't be any more complex than that. It would add maintenance costs for sure, but calling it a logistical nightmare seems like an exaggeration.
Most use a horizontal single axis configuration and could just tilt the panels away from the sun.
The real question that we should be asking, is why nobody can think of what to do with free energy?
Desalination? Mine Bitcoin? Giant space laser?
It's not a question of ideas, it's a question of money. Building things to use excess power costs a lot of money.
In some markets, the power price actually goes negative and consumers can be paid to use energy.

I think there's plenty of money out there to use excess power, someone just has to connect the dots...
Or in a pinch: just run big-ass space heaters. Seriously. It's a stupid way to burn off excess power, but it's dirt simple and cheap. Just have a big array of resistive heaters out in an empty field somewhere with a high fence around it. Need to burn off an extra GW? Run it through massive heating elements and burn burn it off. It's a stupid waste of good energy, but as an emergency backup, it's not a bad option. It's trivially easy to dispose of huge amounts of excess electricity if you just run the mother-of-all space heaters. Run your stupid giant resistive heater at the bottom of a lake for even better effect.
You need to consider more than just solar farms. There are many roof top solar systems on people's houses. That's what I'm referring to regarding logistical nightmare.
Second, if we are just going to cover up solar panels, then it really defeats the purpose of having it. A better way is to come up with ways to store this excess energy to use when there is low production and not have to depend on fossil fuels at night.
Yeah I understand storing and using the energy is obviously a better solution than to stop producing the energy. But in the short term, in the context of large solar arrays, until we have storage solutions or ways to use* the excess, covering the panels up or turning them to face the ground for a bit doesn't seem like a very big logisticical hurdle.
Are there really enough residential rooftop panels for this to even be a problem? And couldn't it be solved just by installing a battery for your home to store the excess? Again, if you could explain how this would be a logistical nightmare for my ignorant self, I'd appreciate it.
