Clean Panels Produce More Power. It Really Is That Simple.

Professional solar panel cleaning services to keep your system producing at its peak.

Your solar panels are out in the elements every single day — collecting not just sunlight, but also dust, pollen, bird droppings, and grime. Over time, that buildup creates a barrier between your panels and the sun, and your energy production quietly suffers for it.

Studies show that dirty solar panels can lose anywhere from 15% to 25% of their efficiency. For most homeowners, that’s a meaningful amount of free energy left on the table. Regular cleaning is one of the easiest ways to protect your solar investment and make sure you’re getting everything your system was designed to deliver.

The Rocknoll Difference:

We don’t just spray your panels with a garden hose. Our technicians use purified, deionized water and soft-bristle equipment specifically designed for solar panels — the kind of clean that removes residue without scratching the glass or leaving mineral deposits behind.

Our cleaning service includes:

Safe, non-abrasive cleaning of all panel surfaces
Inspection for visible damage, cracked glass, or soiling patterns that may indicate a larger issue
Rinse and spot-check for streaking
Optional post-cleaning production report so you can see the difference for yourself

We recommend cleaning at least once a year — more often if you’re in a high-pollen area, near a busy road, or have noticed birds taking a liking to your rooftop.
