    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.

    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.

    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.

    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.

    Learning how to clean solar panels can improve the efficiency of solar energy systems and reduce home energy costs. Here are some easy steps for cleaning solar panels.

    Solar panels have become increasingly popular for meeting home energy needs. By absorbing sunlight, they create a current that’s converted to usable electricity. The amount generated depends on the absorption of sunlight, so if solar panels are dirty, they’re not as efficient—or cost-effective—as they can be.

    In general, solar panels require little cleaning and maintenance in areas that receive regular precipitation. Rain can wash away much of the dirt and debris that might block a home’s solar panels from absorbing the maximum amount of sunlight. However, grime can still build up over time. Especially in dry climates or near construction or industrial sites, relying on rain to keep panels clean may not be enough.

    Before You Begin…

    Not all solar panels have the same maintenance suggestions, so it’s important to check manufacturer instructions before doing any DIY cleaning work. Homeowners should also judge their ability to work safely. Suppose the solar panels are too high to reach comfortably with tools or are set in a steep or slippery location. In that case, homeowners should hire professional assistance to avoid potentially serious injuries.

    If DIY solar panel cleaning is feasible, the first step is shutting them off. Solar panels are electrical equipment and should not be cleaned while active. Manufacturer specifications will explain how to make sure electrical currents—both produced by the panel and going into the home—are turned off.

    Standard hardware supplies can be used for a solar panel cleaning project, but safety considerations are critical. A hard hat, ladder support, and harness are recommended for any homeowner who plans to work on a roof instead of from the ground.

    Tips for Cleaning Solar Panels

    • Cooler days are better to complete a solar panel cleaning project because they minimize the risk of cracking glass as the water dries.
    • Abrasive, heavy-duty detergent is not recommended for cleaning solar panels. A small amount of gentle, non-abrasive soap mixed with one part vinegar and eight parts water is an excellent homemade solution for cleaning the glass on solar panels.

    Safety Considerations

    • Solar panels must be turned off before cleaning, and the underside should never be touched.
    • It’s safest to clean solar panels from the ground with extension tools while wearing gloves. However, homes with second or third stories may require climbing up to the roof.
    • Homeowners who are unsure of their ability to clean their solar panels safely should consider calling a local solar power professional to complete the job for them.

    Maybe it’s time to call in a solar energy pro. Get free, no-commitment estimates from experts near you.

    STEP 1: Dislodge any dust, dirt, or leaves with a soft brush.

    Leaves, bird poop, and dust accumulate on solar panels. Even though rain clears away some of this, it doesn’t get everything and can create dirty residue when puddles evaporate. Debris should be removed with gentle brushing from a soft-bristled tool to start the cleaning process.

    This can be done from the ground if the soft brush is attached to a telescopic extension pole with a threaded tip or hook. Some poles can extend to 24 feet. Without a long enough extension pole, reaching solar panels to brush will require an extension ladder. If you need to climb onto the roof, take safety precautions like wearing a hard hat and harness.

    Starting with a gentle brushing is the best way to clean solar panels because if a lot of material is sitting on solar panels, immediately mixing the debris with water might cause spread and smear. Brushing breaks down and removes some material, making the next steps in the cleaning process more effective. Wear work gloves to keep your hands clean and safe.

    STEP 2: Use a garden hose to spray the panels clean.

    Water is a major player in solar panel cleaning. After dry debris is removed by brushing, a garden hose can remove most remaining dirt on solar panels.

    It may be tempting to hit solar panels with as much water as possible to get the job done quickly, but high-pressure cleaning is likely to create fine cracks on their surfaces. This will ruin the efficiency of the solar system and invite future problems. It may also void existing warranties due to noncompliance with manufacturer specifications for solar panel maintenance. If a hose has a high-pressure attachment, it should be removed before solar panel cleaning.

    Maybe it’s time to call in a solar energy pro. Get free, no-commitment estimates from experts near you.

    The key to this step is careful, deliberate spraying along each solar panel. If a garden hose doesn’t allow for enough spraying control, a telescopic hose wand may help. These have more supportive grip than a hose on its own.

    STEP 3: Scrub any problem areas with a soft brush and water.

    After spraying away most of the mess, problem areas can be given extra attention with a sponge, squeegee, or soft cloth dunked into a bucket of clean water. Gentle, focused cleaning in a repetitive motion—with some patience—is best since aggressive scrubbing can scratch the panels.

    Even cleaning products deemed “safe” for use on solar panels can be abrasive. Water is the best solar panel cleaner, especially if it’s deionized or distilled. This water attracts other chemicals, so it’s more efficient for cleaning. If deionized or distilled water isn’t available, treating hose water with a water softener can help improve its cleansing power.

    If there are stubborn spots that water can’t handle, a squirt of mild, gentle dish soap mixed with one part vinegar to eight parts water can boost cleaning power. However, any soap should be used sparingly and with caution. When soap is rinsed, it can leave a residue that dirt clings onto in the future, leading to streaky solar panels. Not only is this less aesthetically pleasing, but it can also compromise some of the panels’ functionality.

    STEP 4: Monitor your home’s solar output to measure the cleaning’s impact.

    Because solar panels create usable energy by capturing sunlight, giving them more sunlight will increase their solar output, or how much power they produce. This is why solar panels are most often set up in sunnier locations. Based on the specifics of the solar system, its location, and environmental factors, solar panels are rated for a solar output within a specific range of watts.

    clean, solar, panels, garden, lights, windex

    Normal operating conditions cause fluctuation within the predicted range. When solar panels are dirty, however, they produce energy at the low end of the range. With a lower solar output, homeowners rely on power from an additional energy provider, driving up energy bills and time in the solar payback period.

    To determine how much impact cleaning solar panels has, homeowners should review their energy bills before and after the cleaning. Clean solar panels will have lower energy costs because they allow maximum exposure and higher solar output.

    Maybe it’s time to call in a solar energy pro. Get free, no-commitment estimates from experts near you.

    STEP 5: Contact a solar panel professional for complex cleaning and maintenance needs.

    If cleaning solar panels seems more dangerous than beneficial, contacting a professional is a practical solution to improving solar output. Even though solar panels don’t need constant cleaning, removal of build-up is part of their maintenance. Finding a solar panel cleaning professional is best for conditions that are too complex to tackle with a garden hose and sponge.

    Solar panels cannot be used while they are being cleaned. If professional services are hired, they can work to turn off the electricity and do the cleaning, putting homeowners at ease and giving them confidence that their system will not be impaired through electrical error.

    To get the most out of a professional solar panel cleaning service, homeowners can begin a mock version of the cleaning process. They can clear leaves or large debris to get a good idea of specific cleaning problems that need to be addressed.

    Since solar panels are often set on roofs or high areas, cleaning solar panels requires careful attention to safety. Only solar panels that are easy and safe to access should be cleaned without professional services.
