At Jani Solar, we want to provide solar panel owners in Dallas-Fort Worth with honest and practical recommendations for solar cleaning. While regular cleaning is essential for maintaining solar efficiency, the frequency often suggested by others is not always cost-effective.
​
The cost of professional solar panel cleaning in DFW typically ranges between $5 to $10 per panel, depending on factors such as paint overspray, roof steepness, and system size. Many companies recommend cleaning twice a year or at least once annually, but in our experience, this isn’t necessary for every homeowner. For most homes in DFW area they can go years without needing cleaning.
​
We have been providing solar maintenance and cleaning services in the DFW area for years, and we generally advise our clients to schedule a professional cleaning every three years. However, this may vary based on your environment—if you live in a high-construction zone or an area with heavy tree coverage and pollen buildup, more frequent cleanings may be beneficial.

Is Solar Panel Cleaning in DFW Necessary? Here's What You Need to Know
When Should You Clean Your Solar Panels? Signs It’s Time for Maintenance
Over time, dust, dirt, and debris can accumulate, reducing efficiency. Here are common signs that indicate your solar panels need cleaning:
​
-
It’s Been Over Four Years Since Your Last Cleaning – If you haven’t had your solar panels professionally cleaned in several years, dirt, pollen, and bird droppings may be affecting performance.
-
Persistent Dirt After Rainstorms – While rain can wash away some dust, it doesn’t remove built-up grime. If your panels remain dusty or streaked weeks after a storm, they may need a thorough cleaning.
-
Noticeable Bird Droppings and Debris – Large amounts of bird droppings, leaves, or other debris can block sunlight and significantly reduce energy production.
-
Living Near Construction, Highways, or Farmland – Areas with high dust levels, construction activity, or heavy pollen may require more frequent solar maintenance to keep panels clean.
