GOOD TO KNOW:  Frequent question: How do plants obtain their energy rich compounds?

Are dirty solar panels less efficient?

They found that solar panels in very dirty environments saw a 25 percent drop in efficiency from atmospheric pollution alone. Combining these two effects, a solar panel located in a heavily polluted environment that hasn’t been cleaned in a month or more might see a total efficiency drop of 35 percent or more.
