Pollen Season & Solar Panels: What You Should Know

Fri, 20 Mar 2026 16:30:00 GMT

How Pollen Affects Solar Panels

If you're a local to the Southeast, you know that March typically kicks off what is known as "pollen season." While most people notice pollen accumulate on cars, decks, and outdoor furniture, most people aren't thinking about their solar panels.

Pollen is made up of extremely fine particles that spread far and wide through the air. When pollen collects on solar panels, it forms a thin yellow film across the surface. Even a light coating can interfere with how sunlight reaches the solar cells.

Instead of light passing directly through the glass, some of the light is actually blocked by that pollen layer. Over time, this reduces the amount of energy the panels can produce.

Unlike heavier debris such as leaves or dirt clumps, pollen spreads evenly across the panel , meaning the entire surface may be affected rather than just one small section.

Why Pollen Sticks to Panels

Pollen isn't just dry and dusty. It's naturally stick. This is nature's design so pollen can cling to insects, animals, and surfaces to help spread during pollination.

That same stickiness means its easy for pollen to adhere to solar panels. Once it settles on the glass, it can combine with:

Morning dew
Humidity
Light rain
Airborne dust

This mixture can form a thin film that bonds to the panel surface more than ordinary dust would.

Why Rain is Not Enough

A common assumption is that rain will wash pollen away. In reality, rain usually moves pollen around rather than fully removing it.

Think of it the same way as a car during pollen season. After a rainfall, the vehicle might look slightly cleaner, but a hazy film or streaking often remains on the paint and glass.

Solar panels behave similarly. Rain may remove some loose particles, but it rarely provides the kind of rinsing and agitation needed to fully clear sticky pollen buildup. Imagine not washing your car for years and living in the Southeast - yikes.

Over time, layers of pollen and residue can remain on the panels until they are properly cleaned.

When is Pollen the Worst?

In most of the Southeast, pollen levels peak during the Spring months of March through May. During this period, it's common for solar panels to accumulate noticeable buildup within just a few weeks.

Trees are a large contributor to pollen buildup, followed by grasses and other plants.

So What Do You Do?

Having your panels cleaned right before or during pollen season is generally not the best idea. They will simply get coated again and we do not recommend that to our customers.

What we advise is to have them professionally cleaned after the pollen season is over, to ensure they're nice and clean to head into the high-production Summer months.

The months following pollen season are always our busiest time of year and appointments go quick.

We highly recommend scheduling a time for your cleaning ahead of time. You can do so using the form below!

The Importance of Strong Critter Guards

Sat, 07 Feb 2026 21:09:57 GMT

Not All Solar Critter Guards are Created Equal

Solar panel critter guards are by far the best way to protect the underside your solar system from birds, squirrels, and other wildlife. Unfortunately, there's something some homeowners don't realize until it's too late.

Not all critter guards are built the same.

The material, strength, and construction quality of a critter guard directly affects how well it protects your system - and how long it actually lasts your system. We're so confident in our critter guard systems, we stand behind them with a 10 year warranty.

The Problem With Cheap Critter Guards

There are plenty of low-cost critter guard options available. They can be purchased through Amazon, Home Depot, Lowes, etc. and many look fine at first glance. However, over time, they tend to fail for a few common reasons:

Made from flimsy plastic materials
Made from thin, flexible metal that bends easily
Weak coatings that corrode over time and then rust
Poor fit that leaves gaps for animals (1 inch of space is all a squirrel needs)
Fasteners that loosen or pull away

Once a guard bends or separates, animals only need a small bit of effort to get underneath your panels and start nesting and/or causing damage.

A failed critter guard is often worse than no guard at all, because most homeowners assume their systems are protected when they're not. See an example below of a failed plastic critter guard system.

Strength and Stiffness Matter More Than You Think

Solar critter guards don't just need to hold up to animals, they need to hold up to environmental forces as well. They're constantly exposed to:

Wind uplift
Temperature swings
Animals trying to tamper with them
UV exposure

If your critter guards lack stiffness and strength, they will begin to flex, deform, or detach over time. That's why we only install guards that are structurally rigid, resistant to bending under pressure, and designed to maintain their shape for years to come.

Material Quality Makes a Huge Difference

Solar critter guards don't just need to hold up to animals, they need to hold up to environmental forces as well. They're constantly exposed to:

Wind uplift
Temperature swings
Animals trying to tamper with them
UV exposure

What Do We Use?

At Solar Clean Pros, our business is based delivering amazing results. That means for critter guards, we only use the best of the best. Our critter guards are manufactured in the USA and custom bended by us to your system. This gives us complete confidence in:

Material consisitency
Quality control
Strength standards
Long-term reliability

When it comes to protecting an expensive solar system, cutting corners on materials isn't in our playbook - delivering a long-lasting system to keep your panels safe and secure is.

What Are The Effects of Soiling on Solar Panels?

Fri, 06 Feb 2026 01:38:36 GMT

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.

Let's Talk About Solar Panel "Soiling"

In terms of solar panels, soiling refers to any material that accumulates on the surface of a solar panel and blocks sunlight from reaching the cells effectively. Common sources include:

Dust and dirt
Pollen and organic debris
Bird droppings
Salt residue (looking at you coastal solar owners)

Because solar panels rely on direct sunlight, anything that interferes with light transmission can reduce output.

Ho w Soiling Impacts Energy Production

Soiling can reduce solar performance in a couple of ways:

Less Light Reaching the Cells:
Debris scattering across the surface and blocking sunlight, lowering usable energy converted into electricity
Uneven Soiling Causes Disproportionate Losses:
Uneven dirt patterns and obstructions like bird droppings can hurt output more than uniform soiling

A 2023 peer-reviewed study published in Sustainability (MDPI) found that soiling losses vary significantly by environment and conditions, but consistently result in measurable efficiency reductions when panels are left uncleaned over time. This study also highlights that soiling is a site-specific issue, meaning that your climate, surrounding land use, and weather patterns play a major role in performance drops.

That means that two systems installed in the same year, could perform very differently based on cleanliness of the panels.

Reduce Soiling Losses with Preventative Maintenance

The good news is that soiling is an easy performance problem to correct!

Regular professional cleanings (even if just annually), can help to:

Restore some lost efficiency
Prevent uneven buildup and hot spots
Extend the effective lifespan of your solar system
Protect your return on investment

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

Sat, 17 Jan 2026 00:17:37 GMT

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.

Visual Panel Condition

We start with a full visual assessment of your panels, frames, mounts, etc. to check for:

Cracks, chips, or impact damage
Delamination or discoloration
Hot spot indicators or burn marks
Excessive surface grime or staining
Warping
Excessive debris buildup under panels

Minor surface damage can reduce energy production or worsen overtime, especially under the added stress of direct sunlight.

Soiling & Debris Buildup

Dirt, pollen, dust, bird droppings, leaf & tree debris are all among the most common things we see causing reduced performance.

We will assess the degree and type of soiling your panels have as well as any excessive shading or partially obstructed cells. Heavy or uneven soiling on your panels' surface often explains unexpected drops in production and is a relatively easy issue for us to address.

We also thoroughly inspect underneath your panels to check for any buildup of debris like leaves, pine needles, nests, and other organic matter. Aside from reducing airflow for cooling, this can also trap moisture on your roof's shingles.

Wildlife Activity & Nesting

Solar panels create a protected environment that attracts birds, squirrels, and other small animals. During our assessment, we will look for:

Nesting materials under panels
Chewed wire or damaged conduit
Droppings, feathers, or food debris
Signs of repeated animal access

Damage from wildlife can create safety hazards, reduce airflow, and lead to expensive repairs if not addressed.

Mounting Hardware

Your mounting system is designed to keep your panels securely mounted and properly angled. During our cleanings, part of our inspection includes checking for:

Loose or missing fasteners
Improper spacing or shifting
Corrosion on rails, clamps, or other hardware
Mounting system stress

Hardware issues can compromise panel alignment, efficiency, and overall safety. In more severe cases, it could damage your roof.

While we are not roofers, we do visually assess your roof and the areas around your solar system for things like:

Trapped moisture from debris
Roof surface wear around mounting points
Blocked drainage paths
Obvious damage

These factors can indirectly affect your solar system and roof longevity. Since most homeowners do not thoroughly inspect their roof and solar panels yearly - scheduling a cleaning has some added benefits!

Roof & Surrounding Area Check

We do not perform electrical repairs, but we do look for warning signs that could indicate further evaluation may be needed, including:

Loose, exposed, or frayed wiring
Damaged conduit
Burn marks or abnormal discoloration
Visible inverter error indicators

If we spot anything concerning, we will generally recommend contacting your installation company to complete any repairs.

Electrical Red Flags

Routine Inspections Matter!

Keeping an eye on your solar investment helps maintain the longevity of your system. At Solar Clean Pros, multi-point inspections are part of every cleaning to make sure your system is operating safely at its best.

Signs Your Solar Panels May be Underperforming

Thu, 27 Nov 2025 18:35:34 GMT

Common Signs of Underperformance ��

Your solar system is supposed to deliver predictable savings. If output drops, even slightly, you could be losing out on cost savings and compromising efficiency. You might even be shortening the lifespan of your system!

Sometimes underperformance happens gradually, so you might not notice until your energy bills go up or a system alert shows a problem.

We're going to talk about some clear signs causing your solar system to underperform and what to do about them.

Unexpected jump in your energy bill: if your home's power usage is staying roughly the same, but your electricity bill is rising or spiking, that can be a red flag. It could indicate that your solar output has dropped, and small drops can make a noticeable difference.
Noticeable soiling or other contaminants: Dust, debris, bird droppings, and other "soiling" on your panels can contribute to reduced energy production. Research shows that shaded and otherwise obscured cells can contribute to poorer performance.
Extremely hot weather: Solar panels can reach temperatures of 150ºF or even higher. During these extreme conditions, performance can decline somewhat.
Large amount of shading: Trees, chimneys, structures and other nearby buildings, or even new construction can significantly reduce output.
Bad Panel or "String": A singular weak-link of your system (or multiple) can drag down the performance of your array. Whether it's due to manufacturing defects, damage, shading, or soiling - it's important to make sure your system is working cohesively.

What Can You Do?

Monitor your panels closely

Here's a few tips you can use to get the most out of your solar system

Use a monitoring system such as one that comes with a mobile-app to track output trends over time. Compare performance against expected production.

Regular cleanings, even just once per year, helps restore light access to your panels by removing all soiling and accumulation from the surface. Especially if you live in a region with heavy dust, pollution, or the lovely southern pollen - cleaning can make a big difference.

Plus, every cleaning visit from Solar Clean Pros includes a multi-point inspection of your system to catch problems early.

Schedule Regular Cleanings

Have a Professional Inspect Electrical Components

If output is low and your panels are not dirty or shaded, it might be an electronic issue. Consider having an experienced professional inspect system components like wiring, inverters, meters, etc. to ensure everything is working properly.

Trim Nearby Trees

If you have large trees that hang over your solar system, consider trimming them to prevent them from blocking your panels. Please consider your own safety first and always use safety equipment or hire a professional.

Don't Wait Till It's Too Late!

Solar panels are intended to be low-maintenance, but they are not maintenance-free. A small problem today (dust, debris, dirt, shading, failing components) can turn into months of lost production. Without resolve, that can mean thousands of dollars lost over the lifetime of the system.

If you suspect your system might be underperforming, don't guess - check! And if you want a professional to clean, inspect, or diagnose, reach out to Solar Clean Pros.

Birds, Squirrels, and Solar Panels; Why Wildlife Love Your Solar Panels

Wed, 15 Oct 2025 12:00:42 GMT

A Hidden Problem You Might Have on Your Roof

Solar panels are a great investment for your home’s energy efficiency and sustainability. However, there’s one problem with them that the homeowners we talk to rarely expect: how much wildlife might love them too. If you’ve ever noticed animals scurrying around your panels, seen nesting material underneath them, or even heard noises from inside your home, you’re not going nuts (the squirrels are).

At first glance, it might seem harmless to leave your panels alone and let wildlife interact with them. It’s just a few birds looking for shade or a squirrel stashing food right? Not always. Beneath your panels, these critters could be causing serious issues for later.

Why Animals Love Solar Panels

From a high-level (like a bird’s-eye view ��), your solar panels look like the perfect shelter. Animals are drawn to them for a few main reasons:

Warmth & shelter: The space beneath your panels provides protection against the elements and even predators. On the hot summer days, your panels provide a source of shade and on the cooler days, they still provide a source of radiating warmth.
Safe hiding spots: Squirrels and other small critters may love enclosed, shaded areas to hide from predators like hawks and your neighbor’s cat.
Ideal nesting space: Wildlife like birds, squirrels, and possibly even racoons use the protected gap beneath the panels to store food and build nests.

The Damage Wildlife Can Cause

While these critters may seem harmless, wildlife activity under your solar panels could lead to some costly issues such as:

Damaged wiring: Squirrels and other critters that are notorious for gnawing on electrical wires can cause shorts and outages, or even fires. If you have any exposed wires under your panels they could be at risk. This is why we conduct thorough inspections at our solar cleaning appointments to catch problems early.
Blocked airflow: Nesting materials and debris could trap heat and reduce your systems’ ability to cool effectively
Roof damage: Trapped moisture from built up debris can corrode racking systems or deteriorate roof shingles over time.

Ignoring these issues can mean reduced performance or some seriously expensive repairs.

How to Prevent Wildlife Intrusion

The good news is that these problems are really easy to prevent, and your team at Solar Clean Pros is here to help. We recommend these proactive steps to prevent costly effects of wildlife intrusion:

Schedule routine cleanings & inspections: Regular maintenance keeps panels clean and clear of debris. Because we conduct thorough inspections of your system during our solar panel cleaning appointments, we can identify signs of wildlife activity and other problem areas.
Install solar critter guards: These durable protective barriers block access underneath your panels while maintaining proper airflow. They’ll keep the area under your panels neat and free of critters and debris.
Remove nests: Always leave nest removal to the professionals to ensure it’s done humanely and safely. Beyond that, climbing to your roof can be dangerous without the proper equipment and procedures. Please feel free to inquire with us regarding nest removal from your solar system.
Prepare for seasonal activity: Fall and Spring area peak nesting seasons for lots of species, which makes these times optimal for inspection and cleaning visits.

Why Critter Guards are Worth It

As you’ve read, critters have a serious impact on your panels - an area many homeowners may not be thinking about. Fortunately, critter guards are one of the most effective long-term solutions for protecting your solar investment. Solar Clean Pros proudly installs critter guards throughout South Carolina, North Carolina, and Virginia!

Fall Solar Panel Cleaning: Why Now's the Time

Sun, 05 Oct 2025 23:52:59 GMT

Why Fall Matters for Solar Panel Cleaning

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.

What's Building Up on Your Panels?

Dirty Panels = Wasted Sunlight

How Solar Clean Pros Can Help

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.

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

Using our multi-step water filtration system and our solar-safe brush systems we will restore your panels to their former glory. Not only will we clean them thoroughly without spots or residue, we’ll also complete a full inspection of your system to let you know if we spot any problem areas.

Ready to head into Fall and Winter with the confidence of a clean solar system? Fill out the form below to request more information and schedule your solar cleaning:

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.

We've Got a New Look

What is Deionized Water and Why Does it Matter for Solar Panel Cleaning?

Fri, 25 Jul 2025 16:30:00 GMT

What is Deionized Water?

If you’ve invested money into a solar panel system for your home or business, it’s important to keep them clean. It’s not just about looks though - it’s about performance. However, not all cleaning methods are the same. One of the most important aspects of our cleaning process is the deionized water that we use during our service. In this post, we’ll explain what deionized water is, why it matters, and how we use it at Solar Clean Pros to help your panels perform at their best.

Deionized water, or “DI water” for short - is water that has been purified to remove virtually all of its mineral ions, such as calcium, sodium, and iron. These minerals are usually found in water from your tap or hose spigot and are responsible for annoying water spots and streaks when things dry. You may also be familiar with the term “hard water” which is water that is particularly high in calcium and magnesium.

Why Tap Water Doesn't Cut It

At first glance, using a hose with water from the spigot might seem like the best way to clean your panels. Here’s the catch: when tap water dries, it usually leaves behind mineral deposits. This is especially true in areas with that hard water mentioned earlier. These deposits can build up over time and will lead to a coating on the surface of your panels. Even small amounts of mineral residue can cut into your system’s energy output, especially during the Summer months when solar production should be at its peak.

We pride ourselves on our onsite filtration to keep our process streamlined and unique to Solar Clean Pros. The process starts with a standard water supply such as water from your home’s spigot and then moves through a series of filters:

Sediment filtration removes large particles like sand or grit that could clog downstream equipment.
Our carbon filters eliminate the chlorine and organic compounds to protect the next stage
Reverse osmosis (RO) filter strips out the majority of total dissolved solids (TDS). Our RO process typically achieves around 90% removal of TDS
Then, our deionization (DI) resin filter captures the remaining impurities, reducing the water to 0 TDS - leaving you with purified, spot-free water

This purified water is stored in our tanks and later delivered through our telescopic water-fed poles that extend to reach even the most difficult areas of your solar array. The brushes on our water-fed poles use gentle boar’s hair heads and we equip them with scratch-free scrub pads for safely agitating dirt. We use safe pressure settings to prevent any damage to your solar system.
Our setup ensures we’re cleaning your panels safely and effectively with no harsh chemicals, no streaks, and no high-pressure jets.

Using DI water solves those issues by drying crystal clear - no streaks, spots, or buildup. That’s why we pride ourselves at Solar Clean NC for executing a professional solar panel cleaning for our customers. Here’s a few key benefits:
Spot-free drying : no white stains or streaks left behind

Gentle and safe : reduces the need for heavy chemicals and detergents

Protects panel efficiency : keeping panels clean makes sure they’re operating at peak levels

Our Best Practices for Cleaning Solar Panels

Why Using Deionized Water Makes a Big Difference for Solar Panel Cleaning

Why We Use DI Water on Every Job?

We are committed to delivering top-tier solar panel cleaning services to homeowners and businesses.. That’s why we use deionized water at every job. It’s part of our promise to use the right tools and techniques to protect your investment and maximize your energy output - without damaging your panels or leaving behind a spotty finish.

Whether you’ve got rooftop or ground-mounted solar panels for your home, we bring the same professional-grade solar cleaning process to every system we clean. As you can see from our process, we put a lot of effort into creating a streamlined process designed specifically for solar panel cleaning. If you are searching elsewhere for a solar cleaning provider, these are questions you should be asking before trusting someone with your solar investment.

What to Know About Solar Critter Guards

Sat, 07 Jun 2025 22:42:00 GMT

The Problem with Roof-Mounted Solar Panels

When installed, solar panels naturally lead to a gap between your roof and the panels. This gap creates a warm, shaded space that can attract animals like birds, squirrels, rodents, and more.
This can lead to a few big problems for solar panel owners. Animals can chew through wiring causing damage, electrical shortages, or system failure. Nesting material under panels causes ventilation issues and could even be a potential fire hazard in the worst-case scenario.

What are Critter Guards?

How Do We Install Them?

Are Critter Guards Worth the Cost?

Ready to Protect Your System?

Critter guards are durable, weather-safe barriers that line the perimeter of your solar array, keeping pests out and eliminating the accumulation of debris underneath your panels. They are typically made from either plastic or a strong, coated mesh (our preferred method for durability) and do not affect panel performance in any way!

Our critter guard installation process is safe, non-invasive, and system-friendly:

We begin by inspecting the array and surrounding roof area to identify pest activity and ensure we have a safe working space to conduct the installation.
Next, if using mesh, we custom-bend to fit tightly and cleanly around the perimeter of your panels.
We then attach the mesh to your panels using no-drill fittings to eliminate all risk of damaging your expensive panels. We pride ourselves on our non-intrusive installations.
Lastly, we wrap up with a quality check and cleanup, ensuring a perfect installation. We take pictures all throughout the process and share with you at the end.

If your home is in an area with tons of wildlife or known pest issues, critter guards can be a smart preventative measure for your solar system. The cost of repairing chewed wires or other damage can often exceed the cost of critter guards multiple times over. These wildlife barriers can be a great way to prolong the life of your solar panels.

Solar Clean Pros is based in Raleigh, NC and we install critter guards on both new and existing solar systems in North & South Carolina and Virginia

Importance of Solar Panel Maintenance for Coastal NC Homes

Fri, 16 May 2025 13:00:00 GMT

Why Coastal Homes are Different

The Impact of Salt & Sand on your Solar Panel System

Regular Cleaning for Coastal Solar Systems Pays Off

Solar Clean Pros: Coastal Solar Care Done Right

What Coastal Areas Do We Service?

Coastal North Carolina has some great conditions for solar power: long sunny days and open rooftops (sometimes with very minimal obstruction). Because of this, it’s no surprise more NC coastal homeowners are turning to solar energy solutions for their beach homes.
However, living near the ocean comes with some challenges that our inland customers do not face - salt spray, sand, high winds, and greater humidity. These conditions can put extra stress on your solar system over time. Without regular cleaning and maintenance, this can reduce your system’s performance and even shorten its lifespan.

Unlike inland homes, coastal homes are constantly exposed to salt-laden air and fine sand particles. Over time these elements can do a few harsh things:

Leave behind salty re sidues that corrode
Create abrasive layers on glass surfaces, reducing light absorption
Increase the risk of long-term system damage if not cleaned properly

Even panels advertised as “coastal-safe” or “coastal-resistant” should still be routinely cared for to stay that way. Think about the underside of vehicles constantly exposed to salted roads. What happens to them overtime? Corrosion and degradation from rust.

Salt and sand buildup doesn’t only affect looks - it directly cuts into your energy production over time. Clean panels can improve output by over 20% in some cases! This means lower energy bills and a longer system lifespan. Professional solar panel cleaning ensures a few key things:

Gentle removal of abrasive particles
Use of non-corrosive, deionized water
Full inspections to catch early signs of corrosion and wear.

Coastal homes can also face more extreme winds, storms, and moisture than our inland customers will experience. Routing cleanings with inspections lets us check mounting hardware and seals, identify loose components early, and prepare your system for storm seasons.

Living on the beautiful North Carolina coast offers incredible solar potential (aside from some great views), but only if you give your system the attention and care it needs. At Solar Clean NC, we specialize in maintaining and protecting solar systems with professional cleaning.
Contact us today to schedule your cleaning & inspection and keep your system running at its best, season after season.

At Solar Clean Pros, we proudly serve homeowners along North Carolina, South Carolina and Virginia's coast

Whether you’re right on the water or further inland, our team has the experience and tools to keep your solar panels clean, protected, and performing at their best in the coastal conditions.

Top 5 Reasons to Clean Solar Panels Before Summer

Fri, 02 May 2025 12:00:00 GMT

Solar Cleaning: Why Timing Matters

As summer approaches, our schedule tends to fill up very fast. By scheduling your cleaning appointment in Spring, you avoid the peak-season rush and start Summer with sparkling clean panels.
Make sure your system is fully prepped before the most demanding months of the year.

#2: Maximize Summer Solar Production

#3: Save on Cooling Costs

#4: Catch Potential Issues Before Peak Heat

#5: Beat the Summer Rush

If you're a native to North Carolina, you know how bad the pollen can be in the Spring. Most panels are left with a yellow-ish film coating that can block sunlight and reduce efficiency. Even rain can't remove the sticky buildup completely.
A professional spring cleaning for your solar panels ensures they are pollen-free and hinders future buildup to keep them working efficiently for the long summer days ahead.

Most homeowners see higher energy production during the summer months due to the longer sunlight hours and better angles. There are also fewer cloudy, dreary days like in the previous Fall, Spring and Winter months.
If your panels are dirty, you won't fully benefit from North Carolina's Summer sunshine.

Our professional cleanings are not just for making them shine again. We also perform a thorough visual inspection of your system to help catch issues early on. This can be anything from wear, loose or frayed wires, pest damage, or other panel issues.
Not every homeowner can or wants to get on their roof to inspect their panels - so we do it for you! Catch issues before the long summer days start!

Your AC system will likely be running full-time or near it throughout the summer. A more efficient solar system can offset those higher bills, but only if it's performing its best. Filthy panels that aren't collecting full sun are going to dull your production.

#1: Post-Pollen Spring Cleaning

How Often Should North Carolina Homeowners Clean Their Solar Panels?

Fri, 11 Apr 2025 12:00:00 GMT

Why Solar Panel Cleaning Matters in North Carolina

Solar panels are a great long-term investment for your home, but like anything else constantly exposed to the elements, maintenance is required for continued optimal performance. While solar panels may be a low-maintenance add-on, they are not a no maintenance add-on.
Whether you're a born and bred North Carolinian or even just moved here within the last year, it takes one Spring to know that amongst other dirt, dust, and debris that accumulates on everything - we get pollen. Lots of pollen.
Most solar panel owners do not know that their array should be cleaned regularly to ensure optimal performance. Imagine if you left your car outside for years, without ever moving it or thoroughly cleaning it. Imagine how clouded the windshield would be with filth. Do you think you'd even be able to see out of it? Sure, the rain might get some off - but it's just going to keep building up.
This is what we see time and time again with solar panels. An entire array, clouded with accumulation. That's where we come in.

Factors Affecting Cleaning Frequency

Our Recommendation for Solar Cleaning Frequency

One of the most common questions we get is "how often should I clean my solar panels?"

It's a great question and the answer is: it depends. On average, most homeowners would benefit from one to two well-timed cleanings per year. Our recommendation, at the very least, is once after pollen season hits.

The degree of buildup on your panels depends on a variety of important factors like your location, tree coverage, bird activity, air quality, and roof pitch to name a few. Let's look into these further.

Signs It's Time To Clean Your Panels?

Tree Coverage

Not sure if your system needs cleaning? Some of the key signs can be a noticeable drop over time in solar energy production, visible buildup on the surface, or if its been more than 6-8 months since your last cleaning.

Pollen Season

Bird Activity

Air Quality

Roof & Panel Pitch

If your North Carolina home is completely surrounded by trees, particularly pine and hardwoods, you'll probably experience faster buildup from falling leaves, sap, pollen, or even bird activity. The greater amount of shade can also mean more moisture and allow grime to build up more.

North Carolina is known for its thick, yellow coating of pollen that comes around during the Spring. The sticky residue that it leaves does not easily wash away with rain and creates a film over your panels' surface that can reduce your ability to capture sunlight optimally.

Bird droppings are more than just unsightly - they can actually damage your panels over time. If left on the surface, the acidic nature can have a corrosive effect on the protective coating of your panels. They can also contribute to hotspots.

If you live next to a very busy road, construction areas, or even farmland, your panels could be subject to greater levels of particulates in the air which can accumulate on the surface of your panels. Over time, this reduces panel transparency and overall energy output

Flatter roofs with panels tend to do a better job at collecting dirt, grime and debris than steeper, slanted roofs. The rainfall may help rinse off loose dust, but it's usually not enough to rid your panels of the more stubborn buildup. Steeper panels may benefit more from rain, but often marginally.

Pollen Season in North Carolina

If you're a native North Carolinian then you know exactly what to expect when the Spring months start to roll around. Going out to your car every day to find that lovely yellow, pasty, and dusty coating all over your cars, benches, driveways and more. While it may seem harmless aside from the allergies it can trigger, pollen can actually significantly impact solar panel owners.
Let's explore this some more.

Why is Pollen a Problem for Solar Panels?

Isn't Rain Enough for Cleaning My Solar Panels?

Our Specialized Cleaning Process

This is why Solar Clean NC has developed a professional, effective, and specialized cleaning processes thats designed for solar panels. Our cleaning service includes:

Non-Abrasive Cleaning: we use gentle, yet tough brushes to remove pollen and other grime without scratching or damaging your panels

Comprehensive System Inspection: every cleaning includes a thorough visual check of your system to help catch potential issues early on - or to make recommendations to help prolong the life of your solar system

Solar panels depend on clear, unobstructed sunlight to effectively generate electricity. Even a thin layer of dirt and pollen can block significant amounts of sunlight, thus reducing the effectiveness of your investment. Aside from reducing overall efficiency, a layer of pollen that can never get properly cleaned can eventually turn into hotspots on your panels which reduce lifespan.

Pollen, unlike regular dust or dirt, is an organic and sticky substance that loves to cling to surfaces. Unfortunately, your solar panels are a prime target for pollen accumulation.
As it settles on your panels, it forms a thin and persistent layer that regular rainfall will not completely eliminate. Over the course of many days and weeks as pollination continues, the buildup on your panels only becomes worse.

Many homeowners believe that the North Carolina spring showers can completely wash away the coating of pollen on your panels. The reality is that rain often does a poor job of cleaning your panels and can result in streaks and residues on your panels. In extreme cases where there is severe pollen buildup, you could just end up with clumps that are adhered to the surface.

Invest in Cleaning for Your Solar Farm

Why Is Cleaning a Great Investment For Your Solar Farm?

Investing in regular cleaning for your solar farm isn’t just about keeping your panels looking pristine—it’s a strategic investment that pays dividends in efficiency, longevity, and cost savings. Here’s why maintaining a clean solar farm is a smart business decision:

Maximized Energy Production

Even thin layers of dust and dirt can have an effect on a solar panel's efficiency. In the more severe cases, panel efficiency can be reduced by up to 25% depending on conditions. Other debris like bird droppings can lead to hot-spots on panel surfaces which hurt performance over time.

For the large-scale farms, these losses in performance are multiplied to a much larger scale. This can mean a significant dent in output and therefore, revenue. Routine cleaning is your best choice for making sure your panels are operating at peak performance. Contact us to set up a cleaning agreement for your solar farm.

System Monitoring

Every cleaning from Solar Clean NC includes a full inspection of your solar panel system and supporting infrastructure. This proactive approach ensures not only that panels are safe for cleaning, but helps with early detection of potential issues. Addressing these early helps to mitigate large expenses down the road.

How Do You Clean Solar Panels?

Fri, 31 Jan 2025 09:14:00 GMT

Solar panels are a great addition to your home if you're looking for a way to save money on energy costs and contribute to a sustainable future. However, like many other items in our lives, regular maintenance is required to keep them operating effectively. This is why cleaning solar panels is so important. Let's talk about how to clean them properly.

The Basics of Cleaning Solar Panels

Cleaning solar panels is not as simple as hosing them off or using household cleaners. Letting the rain "do the cleaning for you" is unfortunately not a solution either. Rain can leave behind dirt, pollen, and mineral deposits that only impede on your solar array's performance.

To clean solar panels effectively, we use solar-safe methods that include:

100% Chemical-Free: Harsh chemicals can degrade the surface and/or leave a residue on your panels
Deionized Water: Free of impurities which ensures a spotless, streak-free finish with no mineral buildup
Specialized Equipment: Using non-abrasive tools designed specifically for the job prevents abrading the surface of your solar array .

Safety is a Priority

Cleaning solar panels often involves working on rooftops and other elevated surfaces, making safety a top concern. This is why it's essential to:

Use the appropriate safety gear such as harnesses and other fall-protection equipment
Avoid standing directly on the solar panels to avoid breakage or injury
Exercise caution when working on wet surfaces to avoid slipping

Without the proper equipment, cleaning your own solar panels can be dangerous. Sometimes it's best to leave these things to the professionals.
