Hiring Professional Cleaning Services

On average, depending on how much it costs to clean solar panels, professional cleaning services charge anywhere between $2 and $4 per panel, depending on the size of the panel and the company you hire. If you have a larger system, it’s not uncommon to pay closer to $6 or even up to $12 per panel. That’s a median range of approximately $2-$12 per panel for professional solar panel cleaning services.

So, for a 20-panel residential system, the cost of a professional cleaning service could range from $40 to $240. Some companies even offer discounts when you purchase a package of multiple cleanings, so be sure to ask about that before committing to any one service.

Frequency Of Cleaning

The frequency of cleaning solar panels depends on several factors, such as the amount of dust, pollen, and other environmental contaminants in the air. The average cost to clean solar panels is around $0.15 to $0.30 per watt (or per panel).

So, if you have a 5 kW solar panel system, the average cost to clean solar panels would range between $75 to $150. However, if you live in an area with high dust, dirt, and other airborne particles, you may want to clean your panels more often, which will drive up the total cost. 


On average, it costs between $100 and $400 to clean rooftop solar panels in a typical residential environment. For commercial applications, these costs can increase between 1 and 4 times due to the scale of the operation itself. Depending on the location of the operation, additional costs may apply due to difficult access or complex structures to clean.

Property owners may also be responsible for additional costs related to tools, transportation, and the use of hazardous materials. If the solar panel system includes ground and roof-mounted home solar panel systems, the costs can vary depending on the complexity of the cleaning procedure.

System Size

Generally speaking, the larger the solar panel system, the more it will cost to clean it. For a small residential system of 1-3kW, basic cleaning can cost around $100 and includes cleaning individual panels, a racking system, and then removing and disposing of the debris.

Mid-sized commercial projects (10-20kW) may cost up to $400-500. For a more extensive system (250-350kW), the cost for a basic clean can be anywhere from $ 2,000-3,000, while a deep clean may cost up to $5000. The overall cost will increase accordingly if additional cleaning materials and tools are needed.
