    How to Clean RV Solar Panels to Maximize Their Output

    Knowing how to clean RV solar panels is more important than you may think. Not only are you protecting the surface of the panel, but dirty solar panels mean less power. We know this isn’t rocket science, but it is important!

    When solar panels get dirty from dust, pollen, bird droppings, and tree sap, they lose their ability to produce power. Keeping them clean ensures that they continue to put out the maximum amount of power they’re capable of producing.

    So, cleaning the solar panels on your RV roof several times a year (or more often if you’re like us ) is an important part of the maintenance of your solar system for maximizing solar output. But, the last thing you want to do is use any type of product that might leave a film on the panel.

    Fortunately, caring for your RV solar panels is actually very simple (as long as you have a safe way to access your RV roof).

    So, in this post, we’ll tell you how to clean the panels and what products are best to use to keep your solar panels performing at maximum capacity for many years.

    Is Rain Enough to Clean My RV Solar Panels?

    This is a common question and one we’re tempted to answer with another question: Is rain enough to keep your car or RV clean?

    The answer, of course, is no.

    While rain is helpful in washing away some dirt, dust, and pollen, there are other factors that come into play. These include bird droppings, tree sap, salt, environmental contaminants, and road grime that comes from driving on many different types of road surfaces.

    So, sometimes you have to wash your car using a mild soap to address all of this. The same is true for solar panels that ride along the road with you… and sit under trees, with birds flying above them, etc.

    In addition, rain may push dust and debris toward the frame of the solar panel, which will then dry, impacting the panel’s output.

    Rain is insufficient for keeping your RV solar panels clean and performing optimally.

    Rain is not sufficient for the purpose of cleaning RV solar panels over time.

    Do I Need Special Products to Clean My RV Solar Panels?

    Fair warning: We’re about to step into a bit of a controversial area here.

    There are many articles online suggesting that the only thing you should use to clean any solar panel is de-ionized or distilled water, free of mineral ions and all other impurities.

    Then again, some say you must use a special “solar panel cleaner.”

    Others say the best way to clean solar panels is with hydrogen peroxide or a mixture of vinegar water and special scrub brushes.

    Still, others say you should never use hydrogen peroxide or vinegar on a solar panel. Some even say never to use any type of soap because it’ll leave behind a film.

    While we agree that using any type of chemical or harsh brush or pad is a bad idea, we think some people may be complicating the cleaning of RV solar panels unnecessarily.

    It’s true that chemicals can be harsh and abrasive and may be capable of scratching the surface of the panels, reducing their effectiveness. But the truth is that rigid glass solar panels are pretty durable. The tempered glass is designed to be pretty weatherproof, (including hail, which we can attest to first-hand!), so it’s fairly resistant to most things.

    What you don’t want is for dust, pollen, dirt, tree sap, and other grime and debris to remain adhered to your solar panels, including around the frame edges. All of that stuff will reduce the panels’ output, and we need all the power we can get!

    So, we’re here to tell you what’s worked successfully for two guys who’ve been on the road full-time in an RV (with solar panels) for over 20 years.

    NOTE: We’re primarily talking about traditional rigid glass solar panels. If you have any type of “flexible” panel, following the manufacturer’s care instructions is the way to go. Not that cleaning them is all that different. But you’ll want to check the owner’s manual to be safe.

    How to Clean RV Solar Panels

    As always, safety first. Anytime you work on your RV roof for any reason, you’ll want to exercise caution. Some RV roofs can be extremely slippery, especially when they’re wet. Even the most agile among us can slip and fall.

    Always use extreme caution when accessing your RV roof.

    Also, not everyone can or wants to do any type of work on the RV roof, and there’s nothing wrong with that.

    Still, someone needs to address the RV roof from time to time, and the cleaning of solar panels every now and again is important. You should be keeping the roof itself clean and preventing RV roof leaks with Dicor maintenance, so solar panel maintenance can be done at the same time.

    So, step one is to use extreme caution accessing and working on your RV roof, or seek assistance from a neighbor, friend, or professional.

    And step two, the actual washing of the panels, is very simple:

    Clean your RV solar panels with a soft sponge or mitt, using the same mild soap you’d use to wash your car or RV.

    Now… we’ll admit that we wouldn’t recommend using just any soap, but we don’t use just any soap to watch our car or RV either.

    Our favorite is Meguiar’s Gold Class Car Wash, which we’ve used on our RV and our car for years.

    Meguiar’s Gold Class washes away the dirt, grime, and other contaminants from driving hundreds of miles along dusty roads. But it’s mild enough not to strip the wax from our rig.

    Meguiar’s is also what we use to clean our RV’s roof… and solar panels. It’s mild, and safe for all paint types and clearcoat. We’ve found it to be very effective and safe for use on our solar panels as well.

    We also use a soft, non-abrasive Microfiber wash mitt. You could also use a soft cloth.

    • Rich and luxurious car wash designed to wash and condition paint in one easy step
    • Premium formula offers rich foaming and sudsing action to gently and safely wash away tough dirt, road grime and contaminants without stripping wax.

    How To Clean Solar Lights With Toothpaste Or Vinegar [Step-By-Step Guide]

    Are your outdoor solar lights starting to accumulate a film of dirt, dust, and grime, but you’re not sure how to clean them? Well, you’ve come to the right place. We’ve put together this step-by-step guide to teach you two ways to clean your solar lights.

    Toothpaste method:

    Vinegar method:

    You’re probably wondering why you need to clean your solar lights. And are there other household cleaners you can use to clean the solar panels on your lights? Keep reading to learn all about cleaning solar lights and the best ways to do so.

    Cleaning Your Solar Lights

    When dust and grime build up on the solar panels of outdoor lights, it can prevent them from absorbing as much energy from sunlight.

    The debris on the panel blocks the light from reaching it and limits the amount of sunlight the device receives to convert to energy. When a solar light is dirty, it may seem dimmer than usual, or it may run out of power earlier than it normally would.

    Toothpaste Method

    Did you know that toothpaste can be used to clean more than just teeth? It’s perfect for cleaning solar panels too. It has very fine grit in it that works to gently remove debris, buff, and polish. Just make sure you are using a paste and not a gel.


    Start by applying a pea-sized amount of toothpaste to the solar panel, spreading it to cover the entire surface. Gently move your finger over the area in a circular motion to help scrub up any stubborn grime.


    Take a clean, dry microfiber washcloth and begin wiping the solar panel in a gentle circular motion to buff out the toothpaste. Continue to wipe and buff the panel until all the toothpaste is gone and the panel is clean and shiny. Make sure to pay special attention to the edges to make sure you get all the toothpaste off.

    Colgate Baking Soda And Peroxide Toothpaste

    This two-pack of toothpaste is perfect to keep around the house for cleaning things like solar panels. The baking soda in this formula adds some extra grit to help clean surfaces gently.

    The Vinegar Method

    Vinegar can work as a natural cleaning solution and does well at lifting off grease and grime because of its acidity. It even works to dissolve hard water buildup and mineral scale. To use it on solar panels, you’ll want to mix it with water and a little bit of dish soap for a better clean.

    Prepare The Solution

    Combine a 1/4 cup of vinegar with 2 cups of water and a 1/2 teaspoon of dish detergent. Mix the solution well and then pour it into a spray bottle for easy use. If you don’t have a spray bottle, you can mix it in a bucket or a large bowl and toss a washcloth in the solution to clean with.

    Wash The Panel

    Spray the solution onto the panel and use a washcloth to gently scrub up any debris. If you’re using the bucket and washcloth method, make sure to wring it out so it isn’t overly wet when you wash the panel.

    The solution should help lift up any stuck-on debris and get the panels on your solar lights operating at top efficiency again.

    Amazon Brand. Happy Belly White Vinegar

    This vinegar is perfect for household cleaning and for solar panels. Each bottle contains 16 ounces, enough for multiple batches of cleaning solutions.

    Are there Other Cleaning Solutions You Can Use On Solar Panels?

    Using a gentle dish detergent mixed with water on solar is another way to clean them up in a pinch, but it won’t work as well as the other methods. The dish soap will lift a lot of the dirt and grime on the panel, but it won’t do much for mineral buildup. The acidity in the vinegar helps lift mineral stains left by the rain.

    How Do You Clean Cloudy Solar Panels?

    If you’ve tried the methods detailed above and the solar panels on your lights still look cloudy, you can try applying a clear lacquer. Make sure you choose an option that doesn’t contain UV blockers, which can prevent the sunlight from reaching the panel. Spray or paint-on options will both work well.

    Rust-Oleum Clear Gloss Spray

    This clear spray lacquer is a great choice for refinishing the solar panels on your lights. It dries to the touch in 20 minutes to make quick work of your projects.

    What Should You Not Do When Cleaning Solar Panels?

    Avoid using any rough detergents or tools when cleaning your solar panels. Things like scrub brushes, scrub pads, and coarse soaps like Soft Scrub should be avoided. Harsh chemicals like bleach and rubbing alcohol can also cause damage to your panels, so avoid chemical cleaners.

    Do Solar Panels Work When They’re Dirty?

    While solar panels will still function if they’re dirty, their efficiency drops significantly. One study found that cleaning your solar light panels can improve their efficiency by 50% after just a few weeks of outdoor exposure and dirt accumulation.

    This can have a significant impact on the amount of time our solar lights stay on and how bright they are.

    How Do You Know If Your Solar Lights Are Going Bad?

    If you’ve already cleaned your solar lights and given them a few days to soak up some sun but they still aren’t performing to your expectations, then it may be time to replace them.

    Most outdoor solar lights are expected to last three to four years on average, so if they’re nearing the end of their life, it may be a good idea to consider new ones.

    Can You Use Windex On Solar Panels?

    Yes, Windex can be used to clean the solar panels on your outdoor lights. It’s a great, quick solution when you’re in a rush to get your panels cleaned up. It won’t penetrate grime as well as the solutions we’ve previously mentioned, but it will help.

    Windex Original Formula Glass Cleaner

    This two-pack of Windex is perfect for a weekend cleaning your outdoor solar lights. You can use it on the solar panels and the shades for an all-encompassing clean.

    Why Are My Solar Lights So Dull?

    If your solar lights are dull, try cleaning them using the methods we detailed above. After a good cleaning, if they’re still not working properly check the weather. On cloudy and rainy days, they won’t charge up very well. If they’re three years old or older, they may be reaching the end of their usefulness completely.

    How Do You Make Outdoor Solar Lights Brighter?

    If you want to make your solar lights brighter, make sure you also clean the shade that protects the bulb. If the shade is dirty, it will block the light from escaping, causing the light to appear dim. Clean the shade with the same solutions as the solar panels, or just wipe them down with a soapy washcloth.

    How to Clean Solar Panels To Reduce Energy Costs

    Regular cleaning is the key to maintain the efficiency and lifespan of solar panels. If not, the dust and debris accumulated over them can affect its performance.

    But now the real question is – how to clean solar panels safely without harming them. Attempting to clean the panels without proper information can have potential risks of damaging the panels altogether.

    Usually, instructions for maintaining solar panels are mentioned in the manual provided by the manufacturer. However, if you are looking for a detail step-by-step process and in-depth clarifications, then read this article thoroughly.

    Here, in this article, we are going to explore everything related to cleaning solar panels for your reference.

    Is it Really Necessary to Clean Solar Panels?

    Most cases, your solar panels won’t need to be cleaned often if at all. Anything that collects dirt (such as pollen or dust) will be washed away the next time it rains. However, there are times when it may be a good idea to clean your solar panel. It’s worth cleaning your solar panels if you have a lot of bird droppings. Rain might not be able to wash them away very easily so it’s a Smart idea. You might also need to clean your panels if there are droughts in your area.

    How to Clean Solar Panels

    There are two options for cleaning your solar panels: do it yourself or consult a professional. Many solar companies offer this service for a charge. It might be offered as an annual maintenance service or suggested that you have it done whenever they install your product.

    If you are interested in making it your own, you will usually have everything you need at home. It will usually only require a hose and some soap.

    Step 1 – Turn off the Complete System

    Before you begin cleaning the Solar Panels you need to make sure that all power connections have been disconnected. It is dangerous to continue cleaning a Solar Panel that is still in use. You will need to shut down any DC systems in your home. In the case of AC systems, it is enough to shut down the main solar supply switch.

    Step 2 – Disconnect Gutters or Rainwater Collections

    It is important to disconnect rainwater tanks that are being used for rainwater collection. It is crucial to make sure that the water collected does not contain any run-off. Block any gutter pipes on the roof. It can become clogged by the debris and dust that may have been accumulated while cleaning the solar panels.

    Step 3 – Pick a Cool, Mild Time of Day

    You should clean your solar panels on your roof at a cool, mild time of day. This is because solar panels’ glass can get very hot from direct sunlight. If you wash the panels with water, the glass can crack easily.

    Even if the glass isn’t cracked, it can be damaged by the Rapid evaporation water. You can also clean the panels on a cool, mild day, since no one enjoys working in the heat of the sun.

    STEP 4 – Dusting

    Solar panels can become clogged with leaves, bird poop, dust, and other debris. Rain may clear some of the debris, but it won’t remove all. It can also leave behind dirty residue after the puddles dry. To begin the cleaning process, remove any debris by gently brushing with a soft-bristled instrument.

    clean, solar, panels, maximize, their

    If the soft brush is attached with a telescopic extension pole with a threaded tip, hook, this can be done from ground level. Some poles reach 24 feet. An extension ladder is required to reach solar panels and brush without an adequate extension pole. Safety precautions include wearing a hard hat, harness, and climbing on the roof.

    It is best to start by gently brushing solar panels. If there is a lot of material on the panels, mixing water with it immediately could cause spreading and smear. Brushing helps to break down some of the material and makes the cleaning process easier. To keep your hands safe and clean, wear work gloves

    STEP 5 – Cleaning with Water

    Solar panel cleaning is made easier by water. After the dry debris has been removed by brushing, you can use a garden hose to remove any remaining dirt from solar panels.

    clean, solar, panels, maximize, their

    While it may seem tempting to spray solar panels with water to speed up the process, high-pressure cleaning can cause fine cracks to their surfaces. This will cause future problems and reduce the efficiency of your solar system. Non-compliance of manufacturer specifications regarding solar panel maintenance may result in the cancellation of existing warranties. It is important to remove any hoses with high-pressure attachments before cleaning solar panels.

    This step requires careful and deliberate spraying of each solar panel. A telescopic hose-wand might be able to help if a garden hose isn’t flexible enough to spray the panels evenly. These hose wands have a stronger grip than a garden hose.

    STEP 6 – Scrubbing Away Tough Stains

    After removing most of the debris, you can give extra attention to problem areas with a sponge, cloth, or squeegee. It is best to use a gentle, repetitive cleaning motion with patience. Aggressive scrubbing can cause damage to the panels.

    Even safe cleaning products can still be harmful to solar panels. Water is the best cleaner for solar panels, especially if it has been deionized and distilled. Water that has been deionized or distilled attracts other chemicals making it more effective for cleaning. Deionized water or distilled water may not be available. A water softener can be used to improve the water’s cleaning power.

    A squirt with gentle dish soap mixed in one part vinegar to eight portions water can be used to clean stubborn areas. Make sure to use soap sparingly. If not, the soap residue attracts dirt and cause streaky solar panels. This can not only make the panels less attractive, but it can also cause problems with their functionality.

    STEP 7 – Observing the Changes

    Homeowners should examine their energy bills before and during cleaning to determine the impact of solar panel cleaning. Because they have maximum solar exposure, clean solar panels will cost less to run.

    STEP 8 – Contact a Professional Solar Panel Cleaner

    If you are experiencing low energy efficiency even after the solar panels, then may be its time to contact a professional for more complex cleaning and maintenance requirements.

    Are solar panels’ efficiency affected by dirt and other debris? What is the impact of dirt and debris on solar panels?

    Yes, and no. It’s not that much. Yes, dirt and other debris can reduce the amount of sunlight that is able to convert light into energy. The effect on efficiency is minimal – perhaps 5% to 5%. This could translate to a loss of about 20 in your monthly energy bill for a 5kW solar system. It doesn’t matter if it is monthly or all year. Even if you are in areas that have been experiencing drought, it will eventually rain and everything will be washed away. It might even not be worth the effort to clean it all the first time.

    How to Clean My Solar Panels?

    You must remember one important point before you start cleaning your panels:

    • Don’t scratch or damage the glass.
    • There are many different models of solar panel models. It is a good idea to verify with the manufacturer of your product for specific cleaning instructions.
    • You can choose to clean in the evening, morning, or cool days. It’s not a good idea to burn yourself by the heat of hot panels during a sunny day.
    • Do not splash cold water onto a hot surface of glass. This can cause cracks from sudden contraction.
    • To get rid of any traces of dirt, use a squeegee.
    • Do not step on your panels as it can cause damage and premature failure.
    • Avoid using bristles with sharp edges as they can scratch the solar glass.
    • You might find oily stains on your panels if you live near an airport, or along a route used by trucks. You can remove these stains with a rag or some isopropyl alcohol.

    Frequently Asked Questions:

    What’s the best way to clean solar panels?

    You can clean your solar panels with a hose and some soapy water. You can clean your solar panels in the same way you would wash your car at house. You don’t want the panels to be scratched so it’s best not to use any abrasive sponge to apply the soapy water.

    Are solar panels really necessary to be cleaned?

    Solar panels must be exposed to sunlight to generate power. However, solar panel cleaning is not required unless there are high levels of smog or dirt, dirt, or sand blowing accumulated over them.

    How often should solar panels be cleaned?

    In order to preserve the efficiency, effectiveness, and productivity of solar panels, it is recommended that they be cleaned at least once a year. Cleaning may be more necessary depending on the location and level of pollution.

    Can you use vinegar to clean solar panels?

    Yes, you can. Mix 1/4 cup vinegar with 2 cups water. Add half a teaspoon liquid detergent or other non-abrasive soap. You will have a cleaner for your solar panel. It’s that simple!

    How can you get rid of algae from solar panels?

    Lichen can be mistakenly thought to be bird droppings from the ground. However, lichen is much more difficult to clean. We have never been able to clean lichen from a solar panel completely. This is because is very close to the surface and uses only water.

    Can I pressure wash my panels of solar power?

    The exterior of your house, including gutters and roof, can be cleaned with pressure washers. It should not be used on solar panel panels. Although they are easier to clean than their low pressure and reach, there is a risk of damaging panels.

    Is Windex safe for solar panels?

    Windex is an inexpensive and readily available cleaner that’s great for cleaning glass surfaces, such as those on solar panels. It will ensure they run at their maximum efficiency.

    How do you maintain solar panels?

    Let the rain do the job of solar panel cleaning. Monitoring your system’s functioning by monitoring your monthly energy usage and bills. You might notice changes in your electricity bill. It may be time to consider cleaning or other maintenance. You can check to see if your efficiency returns to normal after a rain. If it is, then that’s likely the end. If the functionality continues to act strangely, it could be an electrical problem that needs to be fixed.

    Do dirty solar panels generate electricity?

    The researchers found that solar panel in extremely dirty environments had a 25% drop in efficiency due to atmospheric pollution. These two factors combined could cause a drop in efficiency of up to 35 percent for solar panels located in heavily polluted environments that haven’t been cleaned for at least a month.

    How does cleaning solar panels increase efficiency?

    It is clear that panels with poor efficiency will be cleaned. Many statistical studies show that this efficiency and performance improvement can make a significant difference in residential arrays and in commercial installations.

    This is the question that is asked often, and almost everyone thinks about it in almost the same way. Well, there are many reasons why you need to clean solar panels as you can’t just rely on the rain for it. By the time you wait for the next rain, the solar panel might get covered in so much dust, pollen, debris that it can even stop working in some cases.

    Apart from dust and similar factors, another major enemy that you need to think of is bird droppings. Due to all such environmental factors, cleaning the panels becomes too essential as if the panels are not clean, you cannot expect them to absorb the sunlight well and produce a good amount of power afterward.

    To clean up a solar panel, we would not advise you to climb the roof and do it all by yourself if there are no safety measures. However, if it is fine for you to reach the panels, the cleaning part is pretty easy. There is actually no special equipment needed to clean a solar panel.

    Just like a glass window, the solar panels also have a glass sheet on the upper side, which can be cleaned the same way. You can use a water hose to wash off the dust and scrub off the grime with a soft cloth if needed. over, if there are any stains on the panel, you can even use a mild soap to clean them off.

    As you know, the sun is the only source that can make your solar panels work and produce power for utilization. So, whatever that comes in between the solar panel and the sunrays, causes interruption and affects the overall output. For instance, in the rainy season, the solar panels’ output is usually less than in other seasons, for obvious reasons.

    On the other hand, if you believe that the solar panels perform well when the outside temperature is high, it’s not correct. Like any other machine, solar panels also perform their best when they are cool. Yes, the temperatures will surely be high during the daytime as the sun rays directly fall on the panel. But, as the temperature rises, the voltage of the solar panels decreases gradually affecting the overall power output.

    Final Takeaway

    When invested in solar energy, it is important to consider the maintenance of solar panels as they are main source that converters sun energy to electricity. Though rainfall will remove all the dirt accumulated on the panels, sometimes tough stains, bird dropping make the panels less efficient.

    If you want to clean the solar panels yourself instead of getting professional help, then you can follow the steps mentioned in this article. We have also mentioned some answers and tips you have to consider while cleaning the solar panels.

    We hope the information has helped you maintain the solar panels efficiently. If you still have any doubts, we recommend writing to us in the comment section below. We will reply to them as soon as possible.

    How To Clean Solar Panels, And Why You Should Do It

    Solar panels are a fantastic investment for anyone who wants to reduce their carbon footprint and save money on their electricity bills.

    However, to keep your solar panels operating at peak efficiency, it is essential to keep them clean and free from dirt, debris, and other contaminants.

    In this article, I will discuss the importance of cleaning solar panels, the best methods for cleaning them, and how often you should clean them to ensure maximum performance.

    What Is The Most Effective Way To Clean Solar Panels

    Generally, the most effective way to clean solar panels is with water, a little bit of dish soap, and a large sponge similar to the one you’d use to clean a car.

    An important thing to remember is that you don’t want to do anything to damage the surface of your panels. Before wiping down your panels you might want to use a garden hose to spray down your panels to remove dust and debris. If your try to wipe them clean without water you run the risk of leaving micro scratches, which can begin to reduce the efficiency of your panels.

    You’ll also want to make sure you don’t use anything more powerful than a standard garden hose to spray down your solar panels. A power washer will be way too harsh and can cause scratches, cracks, and knock wire connections loose. The powerful spray could also cause large pieces of debris, such as twigs and tree nuts to become wedged in the framing of your panels.

    Lightly soapy water is really the best cleaning solution you can use. Anything more abrasive than that can potentially eat away at the surface of your panels and create scratches and pockmarks. Some cleaners can also leave a film behind if not thoroughly cleaned off which can begin to reduce solar efficiency.

    • Handle that you can attach your sponge
    • A large, non-abrasive sponge
    • Harness
    • Long garden hose

    Will Cleaning Solar Panels Make A Difference

    A very important thing to remember is that solar power is about the long game. While the money saved trickles in month after month, year after year remember that solar panel efficiency follows a similar pattern. A small amount of dust, hardly any loss of efficiency…but over the years, that dust cakes on and that little bit of lost efficiency compounds.

    The bottom line is that cleaning your solar panels will make a difference. As much as 3.5% to 5% efficiency could be lost each quarter of the year if they aren’t cleaned. Granted, wind and rain will help keep some of the dust from settling, but things such as bird droppings and tree sap take a little more elbow grease to get rid of.

    The most important thing to remember when cleaning solar panels is that it will make a difference. How much of one though, depends on how dirty your panels are and the type of cleaner you use!

    How Often Should You Clean Solar Panels

    Your solar panels could use a proper cleaning twice a year. Of course, this should be increased if you live in an area that has more dust particulates floating around in the air. The time of year you do your cleaning depends on your area and the type of climate and severity of the various seasons.

    Now, twice a year is what’s recommended for thorough cleaning but you may need to clean general debris from your solar panels more often than that. Here are some pitfalls to look out for depending on how severe the weather is in your area during various seasons.


    In the fall, leaves and twigs may fall onto your solar panels and get lodged in such ways that wind won’t blow them away. This means you’ll need to get up there…or hire someone….and clear all of that away.

    Fall is also when hibernating animals may be looking to hunker down for winter. The area in and around your solar panels could be prime real estate for squirrels, birds, and other nesting critters. It may be a good idea to get up there and be on the lookout for any signs animals might be calling your solar panels home for the upcoming winter.
