You’re not summarizing the article fairly. She is saying the soiling mechanisms are environmentally dependent, not that there is no soiling in the desert. Again, it cites an efficiency hit of 50% in the ME. The article later notes that they’ve experimented with autonomous robots for daily panel cleaning, but it’s not a generally solved problem and it’s not true that “the wind takes care of it.”
And you still haven’t provided a source for your claim.
I’m saying the same thing she is, that soiling isn’t as severe in the desert not that it doesn’t exist.
The article itself said the maximum was 50% and it was significantly less of a problem in the desert. Even 50% still beats space by miles, that only increases per kWh cost by ~2c the need for batteries is still far more expensive.
So sure I could bring up other sources but I don’t want to get into a debate about the relative validity of sources etc because it just isn’t needed when the comparison point is solar on satellites.
Shouldn't swarms of quadcopter drones zipping around the panels be able to handle that?
Wouldn't even need to be that 'autonomous', since the installation is fixed.
More like the things simulating fireworks with their LEDs in preprogrammed formation flight over a designated area.
