Keep a bottle of solar panel soap on hand; used sparingly, it can streamline cleaning and protect the glass while reducing rinse time. That solar panel soap, properly diluted, boosts efficiency without harsh additives.

Dry vs wet cleaning: pros and cons

SA’s rooftops bask in a sky-scorching chorus, and clean panels translate heat into watts. With the right solar panel soap on hand, a 10–15 percent uptick isn’t myth—it’s a byproduct of visibility, angle, and a smear-free surface. The choice between dry and wet cleaning matters more than the forecast, because glare is glorious until it steals your sunlight.

Dry cleaning slices through dust with minimal water, a boon in water-wary regions. Wet cleaning, by contrast, reaches into stubborn grime and mineral streaks, offering a deeper cleanse when time and weather cooperate. The balance between these approaches hinges on coating safety, access to water, and the rhythm of maintenance.

• Pros of dry cleaning: low water use; quick sessions; reduced risk of streaks on glass
• Cons of dry cleaning: less effective on baked-on grime; may miss residues on seals and edges
