Solar panels rely on direct sunlight, so when a fine layer of dust builds up over time, it can really cut into their efficiency. I've noticed after a few dry weeks without rain, the output drops noticeably. It's not just cosmetic; that grime blocks photons and can reduce power generation by a surprising percentage. A good rinse or a gentle wipe usually brings them back to full output, but in dusty areas, it's something you have to stay on top of.
