Signs of Dirty Solar Panels
Solar panels make power from the sunlight that reaches the cells, so anything sitting on the glass gets in the way. Dust, pollen, leaves and bird droppings build up slowly, and many homeowners do not notice until the panels look dull from the street. Scheduling solar panel cleaning in Leander, TX at the first signs keeps the glass clear.
Dirty solar panels usually show one or more of these signs. Your monitoring app, if your system has one, is often the first place to see a change.
- A gray or brown film across the glass
- Bird droppings, leaves or pollen sitting on the panels
- Debris packed along the lower edge of each panel
- Lower output than usual on clear, sunny days
- Leaves or nests collecting under the array
- Water spots or streaks left after a light rain
How It Works
Our Rooftop Solar Cleaning Process
Rooftop solar cleaning means working on the roof, so it is a job for a team that knows how to move across shingles without damaging them. Every visit follows the same steps.
- Step 1
Look Over the Array and Roof
We start by looking at the panels, the mounts and the shingles around them. Anything loose, cracked or out of place is noted before cleaning begins.
- Step 2
Wash the Panel Glass
We soft hand wash the glass with gentle tools and cleaning methods suited to solar panels, working carefully so the surface and frames are not scratched.
- Step 3
Rinse and Clear Debris
We rinse the panels clean and clear leaves and debris from around the array, including the gutters below when you add them to the visit.
- Step 4
Share What We Saw
Before we leave, you hear what we found on the panels and on the roof around them. You get an honest view of anything that needs attention.
Why Choose Us
Solar Panel Efficiency and Why Dirt Matters
Solar panel efficiency depends on how much light reaches the cells under the glass. A thin layer of dust spreads across the whole panel, while a single leaf or dropping can shade part of it. Either way, the panel turns less sunlight into power than it could.
Rain helps a little, but it rarely washes panels clean. Light showers can leave streaks as dust settles in the water and dries, and debris tends to collect along the lower frame. A regular cleaning removes what rain leaves behind.
A soft hand wash can improve your panels' efficiency by up to 20%. How much a cleaning changes your output depends on how dirty the panels were, their angle and the weather that season. Your monitoring app or your solar installer can show you how your system performs before and after a visit.
Solar Panel Maintenance and Your Roof
Good solar panel maintenance covers the roof under the panels as well as the glass on top. Panels are mounted through or onto the roof, and every mount is a spot where water could find a way in if the seal fails. Leaves and debris trapped under an array also hold moisture against the shingles.
As a roofing company, we look at the shingles, flashing and mounts around your panels during every cleaning. If we see damage, our roof repair in Leander page explains how we handle it. Panels also shed water and leaves straight into the gutters below, so many homeowners pair a solar visit with gutter cleaning in Leander.
We clean panels and look at the roof around them. We do not repair or replace solar panels, inverters or wiring, so for problems with the panels themselves or the electrical side of your system, contact your solar installer.
What Affects the Cost of Solar Panel Cleaning?
The cost of cleaning your panels depends mainly on how many panels you have and where they sit on the roof. A steep or two-story roof takes more time and care to work on safely. Panels with heavy buildup, such as bird droppings or packed debris under the array, also take longer.
Adding gutter cleaning to the same visit can save a second trip. Your free estimate covers it all in a clear quote with no hidden costs, and first responders, military personnel and senior citizens receive 10% off out-of-pocket projects.
The roof itself can add to the scope. If we notice damaged shingles, loose flashing or a failing seal around a mount, we explain what we found and quote any repair separately. Nothing is added to your bill without your approval, so you always know what you are paying for and why.

Solar Cleaning Questions
Questions About Cleaning Solar Panels
How often should solar panels be cleaned?
Many homeowners have their solar panels cleaned once or twice a year. Panels under trees, near dirt roads or in the path of birds may need it more often. A drop in output on clear days, or a visible film on the glass, is a good sign it is time. A visit after pollen season or a dusty stretch of weather is a common choice.
Does rain clean solar panels on its own?
Rain rinses off some loose dust, but it rarely gets panels fully clean. Light showers can leave streaks and spots as dirt settles and dries, and bird droppings and pollen often stick through a storm. Debris also gathers along the lower frame where water runs off. A professional cleaning removes what rain leaves behind and gives the glass a clear surface again.
Is it safe to clean solar panels myself?
Cleaning rooftop panels means working on a sloped roof, often around electrical equipment, so it carries a real risk of falls. Harsh scrubbing or the wrong tools can also scratch the glass. A roofing team knows how to move across shingles safely and without damaging them. If your panels are on the ground, check your installer's guidance before cleaning them yourself.
Do you check the roof when you clean solar panels?
Yes. As a roofing company, The Kerusso Roofing & Construction looks at the shingles, flashing and mounts around the array during every cleaning. Mounts are places where water can get into the roof if a seal fails. If we see a problem, you hear about it before we leave, along with an honest recommendation on whether it needs a repair.
Can you repair my solar panels or inverter?
No. We clean solar panels and look at the roof around them, but we do not repair or replace solar panels, inverters or wiring. For electrical problems or a system that has stopped producing power, contact your solar installer. If the roof under your panels needs work, we can help with that part and give you a free estimate for the roofing repair.
