Yes, 75% of rating is pretty good....
And dust/haze/high,thin clouds/horizonal positioning, not perpendicular to sunshine, all hurt the solar input. I take a look at my panels about every 3-4 weeks, and they are definitely dusty and have to do a little cleaning. Sometimes a good shower does it for me.
