Fall Solar Panel Cleaning: Why Now's the Time

October 5, 2025

As the days get shorter and the weather starts to shift, it’s easy to forget about your solar panels. However, at Solar Clean Pros, we think Fall is a very important time to keep them in mind. We want to help you get ahead of seasonal slowdowns and ensure your panels are working as efficiently as possible heading into the Fall and Winter. 

Why Fall Matters for Solar Panel Cleaning

Fall brings the nice, cooler weather that many of us have been waiting for. Summers can get long and hot in the Carolinas and Virginia, and Autumn is a nice break from that before the cold kicks in.


However, it also means fewer hours of direct sunlight and lower sun angles throughout the day. That translates to less energy for your panels to convert. We want to make every minute of that sunlight count, and the last thing you want is filthy panels getting in the way of that. 

What's Building Up on Your Panels?

You might be surprised what settles on your panels as Fall sets in. During our post-summer cleanings, we regularly see: 


  • Fallen leaves collecting around or on top of arrays. This can obviously block production if there’s enough accumulation on top of your panels, but it can also build up underneath your panels which restricts airflow. 
  • Pollen and sap left over from the Summer months 
  • Dry dust and light debris that sticks to your panels
  • Occasional buildup of bird droppings, mildew, and grime in shaded and/or humid areas 

Dirty Panels = Wasted Sunlight

Dirt and grime buildup can cut into your energy production significantly! We’ve seen extreme cases where production is reduced by over 10% just due to neglecting cleaning and maintenance. For most homeowners, dirty panels means: lower energy efficiency heading into Winter, lower ROI from your solar panels, missed opportunity to bank those sweet solar tax credits.


You paid good money for your solar system - don’t let grime buildup and debris slowly chip away at your production.

What Are The Effects of Soiling on Solar Panels?

By Boosted Marketing • February 6, 2026
Solar panels are built to withstand the elements, but that doesn't mean they're immune to performance loss. One of the more common (and less understood) causes of reduced performance is due to soiling of the surface: the buildup of dirt, dust, pollen, bird droppings, salt residue, and other airborne debris on the panel surfaces. Fortunately, that problem is what Solar Clean Pros is in the business of solving.

Solar Panel Inspections: What We Look for During Your Cleaning Appointment

Solar panels are designed to be a low-maintenance investment, but that doesn't mean no maintenance is needed. Many customers have performance issues that can go unnoticed for months or even years because they're not visible from the ground. A visual inspection of your system helps catch small problems early, or identify the cause of ongoing problems to protect your performance and hopefully save you from costly repairs down the road. Here's some things we look for in our multi-point inspections that come standard with every solar cleaning appointment.
