Frequently Asked Questions

Everything you need to know about our solar panel cleaning service

At My Window Washing, we recommend cleaning solar panels using deionized water and soft-bristle brushes to ensure a thorough yet gentle wash that won't damage the panels or void warranties. Our team avoids harsh chemicals and abrasive tools, as they can scratch the glass surface and reduce efficiency. We use water-fed pole systems that allow us to safely clean panels from the ground or a secure ladder setup, minimizing risk while reaching every panel.

Yes, solar panels do need to be cleaned to maintain their efficiency and performance. Dirt, dust, bird droppings, and other debris can block sunlight from reaching the solar cells, reducing energy output by as much as 20–30% over time. While rain can help rinse off some buildup, it's not enough to remove stubborn grime or residue.

At My Window Washing, the cost to clean solar panels typically ranges from $150 to $500, depending on factors like the number of panels, roof accessibility, and overall system size. Larger or harder-to-reach installations may require additional time and equipment. We provide upfront estimates based on your specific setup to ensure full transparency.

Cleaning panels often involves working at heights and using specialized equipment like deionized water systems and soft brushes to avoid damaging the glass surface. Improper cleaning methods — such as using abrasive tools or harsh chemicals — can scratch the panels or reduce their efficiency. We recommend hiring a professional for safe and effective results.

We recommend cleaning solar panels in the spring or fall, when pollen, dust, and debris buildup is at its peak but weather conditions are mild. Cleaning in the spring ensures your panels are clear after winter storms, while a fall cleaning removes summer dust and prepares your system for lower sunlight months. However, if you notice a drop in energy output or heavy soiling like bird droppings, it's best to schedule a cleaning right away.
