Consider where most large-scale solar power plants will be put up, and you will see remote lands, deserts and the like.
Regions with a lot of sunshine, a lot of heat and a lot…dust.
That pops up a question: Are the conventional solar panels we use good enough for high dust environments? And a parallel question – are there solar panels we can use that are better suited to high dust environments?
The nice folks at Solar Mango appear to be seized of the matter and have dwelt in detail on this aspect of solar panels for the dusty environment over here. (part of Innovations in Solar series)
