    Before deciding whether you should install solar panels onto your home’s roof, you may wonder about the necessary upkeep and maintenance costs. Good news! Solar panels are a long-term investment that requires very little home maintenance or upkeep to provide you with cost-effective solar energy for up to 25 years. which is absolutely a win for your wallet.

    However, there are a few things to consider when introducing solar panels to your home when it comes to preventative maintenance and repairs. We’ll outline common solar panel maintenance tasks in today’s blog and how much they usually cost to achieve. This way, you’ll be able to make the best decision possible when deciding to invest in solar power.

    Yearly Inspections Solar Panel Cleaning Services

    While solar panels typically require very little maintenance outside of what you visually see, you should professionally inspect and clean your home’s solar panels annually. Doing this ensures that your panels aren’t suffering from any hard-to-see degradation, cracks, debris buildup, or other damage. If you want to ensure that your solar panels have a full and healthy lifespan, maximizing your investment, these routine inspections and cleanings are critical.

    Solar Panel Inspection Costs

    The national average cost of solar panel inspections. with trained professionals, ranges from 150-300. Expert inspections ensure that you’re gaining the maximum return on your solar power investment. In-person assessments conducted by professionals typically FOCUS on functionality and efficiency while searching for damages requiring repair work.

    From top to bottom, qualified inspections need to be thorough, taking into account mounting systems, panel framework, and module clamps, alongside your junction boxes, display meters, and searching for moisture penetration or corrosion. They’ll check for broken glass or signs of cracking, as well as loose wiring and bolts. Inspectors also use on-site records and reference statistics to monitor your panels’ output and evaluate their overall performance and efficiency. It’s also essential to check for any instability or misalignments within your framing system.

    Another thing inspectors will look for is if something is obstructing your solar panels, like buildings or tree branches. If you live in an area without much obstruction, you’ll be in the clear, but if your property has a lot of trees, you might want to factor in the cost of tree trimming into your annual budget to make sure you’ll be getting the most out of your solar panels.

    guide, solar, panel, maintenance

    For a few hundred bucks a year, annual inspections ensure that your solar panels output the necessary energy to power your home and provide a sound energy investment.

    Solar Panel Cleaning Costs

    The national average of professionally cleaning home solar panels costs 150-330. Now, these can certainly fluctuate based on the amount of work required, the size of the solar panels, location, and the height and slant of your roof. Per panel billing can range anywhere from 15-35 a panel. You’ll want to make sure that you schedule cleanings annually and after any extreme weather conditions such as a rare New England hurricane, to ensure efficient and safe solar panel usage.

    While solar panel cleaning costs are relatively inexpensive, it can be a complex task to take on. Professionals are careful to reference your particular panels’ cleaning and maintenance guide while working, so be sure to have that on hand. Professional cleaners also need to take special care not to damage the delicate nature of home solar panels by using only clean water and a sponge to wash the panels in circular motions gently. Expert cleaners also take special care not to use potentially harmful chemicals and cleaning solutions.

    While you may wish to clean your home’s solar panels yourself, we strongly discourage it. Unless done by a trained professional, solar power cleaning tasks can be complicated and even dangerous, if mishandled. Solar panels are sensitive, and the slightest misstep can cause expensive damage, hurting your wallet and your energy investment. Professional solar panel experts can also perform quick inspections while they clean, informing you of any potential damages or necessary repairs and replacements.

    Note: If you do decide to clean your solar panels on your own, it’s crucial that you NEVER use soap. as it can leave a visible residue and can cause dirt to stick and build up on your panels.

    Potential Solar Panel Repair Costs

    Performing the above cleaning and inspection work regularly, you may never need to make any solar panel repairs or replacements. However, severe weather conditions and unfortunate circumstances do happen. You should keep yourself informed of potential solar repair work costs and factor it into your home energy budget.

    If routine inspections and cleaning do find that your solar panels require maintenance or repair work, it’s essential to try and get those tasks accomplished as soon as possible. Neglecting to fix broken or malfunctioning solar panel equipment or components will severely reduce your panels’ energy output, damaging your solar investment. Additionally, ignoring repair work can potentially cause more expensive damages and even fires if not properly handled.

    Solar panel owners typically spend an average of 714 when repairing solar panels. but depending on the type of damage, replacements, or labor necessary, this number can fluctuate.

    According to the most visible repair work such as broken glass, obstructing branches, cracked panels, or corrosion runs roughly from 20-350. Broken inverters or damaged tiling, however, can cost up to 3,000 to repair or replace.

    How Can I Tell If Solar Panels Require Maintenance?

    While you should be able to visually see if your solar panels require cleaning, repair, or replacement work, the best way to check up on your panels is to monitor your solar energy output regularly. Random drops or inconsistent readings indicate that a component may be malfunctioning and in need of repair or replacement.

    There are various factors that you should consider when installing or maintaining your home solar panels. Your location, roof pitch, and system size all factor into the cost of owning solar energy. You’ll also want to monitor your home’s environment, specifically trees and their branches growing near or above your roof. Trees can cast shade onto your panels, causing a drop in energy output, or can even potentially fall onto your roof, causing extensive damage to your home and solar panels.

    Solar Investment: Warranties Budgeting

    While it’s crucial to consider everything outlined and explained in today’s blog when it comes to solar power budgeting, routine inspections and cleanings are the best solutions to keeping maintenance costs low. With proper care, your solar investment pays for its maintenance and beyond, helping you to produce clean, sustainable energy for your home and the environment for years to come.

    Also, be sure to inspect your brand’s particular warranty carefully. Solar power brands, such as BlueSel’s 25-year warranty. cover most maintenance and repair costs, providing you with peace of mind and consistent, long-term home solar power.

    Solar panels are very durable — the best solar companies now offer a 25-year product warranty, and most panels have a typical lifespan of 25 to 30 years. However, photovoltaic (PV) cells are only productive when sunlight can reach their surface, so knowing how to clean your solar panels is important. Read on for a step-by-step guide on how to clean your solar panels to prevent dust and debris build-up from reducing your system’s power output.

    The Importance of Cleaning Solar Panels

    If dust build-up blocks 50% of the sunlight reaching your solar panels, their energy output can drop by half. This decrease in productivity can negatively affect electric bill savings — if you were previously saving 100 each month, you might notice that savings drop to around 50 a month.

    Regular cleaning helps keep your solar panels operating at optimal capacity, which means your system generates its expected electricity output. A dirty solar energy system does not operate at maximum efficiency, which can result in higher power bills and, as a result, a longer payback period. Professional solar panel cleaners use the term “soiling losses” to describe the efficiency loss caused by dust and dirt buildup on your PV system.

    Understanding Solar Panel Components

    Solar panels consist of photovoltaic cells fully encapsulated by other materials, which prevents exposure to dust, dirt, bird droppings and weather conditions. However, grime can accumulate on external surfaces over time, which you should clean regularly. Here are some tips to clean different solar panel components:

    guide, solar, panel, maintenance

    Cleaning the Glass Cover

    A transparent glass cover protects the PV cells in a solar panel. Ideally, you should clean the glass surface with non-abrasive cleaning tools like a soft bristle brush or squeegee. Avoid using wire brushes, roof rakes or any other tools that may leave scratches.

    You can wash solar panels with a garden hose, but you should never do this when they are hot since the drastic temperature change can crack the glass. Keep in mind that solar modules may still be hot after sunset, especially on summer days.

    Make sure you have a clean water supply when cleaning your panels. Washing your panels with hard water will leave behind a mineral layer after the water evaporates, defeating the purpose of the cleaning process.

    Cleaning the Aluminum Frame

    Solar panels have an aluminum frame that holds all other components together. Solar manufacturers use powder coating and other treatments to improve corrosion resistance, making the aluminum frame suitable for outdoor use. However, the frame is constantly exposed to dust, just like the glass cover.

    Since the aluminum frame is corrosion-resistant, you can wash it safely with a standard water hose. Never use a pressure washer: it can damage the seals around the aluminum frame, and you may void the product warranty. Cleaning solutions with detergents or other chemical agents can also damage the seals and should be avoided.

    If your panels have not been cleaned in a long time, washing may not be enough to remove grime. In this case, you should brush away dried-up dirt before using a hose. You should avoid chemical agents in general but can use a small amount of soapy water to clean spots with excessive dirt buildup.

    Cleaning the Polymer Backsheet and Junction Box

    The back of a solar panel is covered with a backsheet, typically made of a durable polymer. The back surface also contains a junction box with electrical terminals used to wire multiple panels into a string circuit.

    Since the backsheet and junction box are not always outward facing, these components require less cleaning than a panel’s glass cover and aluminum frame.

    • In rooftop solar installations, the backsheet and junction box are hidden by a small gap between the back of your panels and the surface of your roof. This positioning creates minimal exposure to dust and dirt.
    • But a ground-mount system or solar carport exposes your panels to dust from all directions. In this case, the back surface may also need frequent cleaning.

    You can follow the same cleaning recommendations for the glass cover and aluminum frame to clean the backsheets. Soft brushes and non-pressurized water are suitable, but avoid pressure washers and chemical agents.

    Never open the junction boxes or manipulate electrical connections in any way. If your solar installation includes a workmanship warranty, you can contact your provider to inspect any electrical malfunctions. Many companies also offer professional solar panel cleaning services.

    When and How Often To Clean Solar Panels

    Many solar manufacturers and installers recommend cleaning your solar panels at least two times a year, but cleaning needs can vary depending on site conditions. Your panels may need additional cleaning if your home is close to a construction site or industrial zone. You can expect large amounts of dust in the air, which can accumulate on your PV system in a short time. Be mindful of locations with high concentrations of trees or other foliage as leaves and pollen can also build up on your panels.

    guide, solar, panel, maintenance

    If you live in a place with frequent rainfall, your panels will require minimal cleaning during their service life since rain washes away most of the dirt for you.

    Preparing for Solar Panel Cleaning

    We at the MarketWatch Guides Team only recommend cleaning solar panels on your own if you can safely access your system from the ground or have a flat roof. The task should be left to a professional cleaner if you need to climb your roof or other tall structure to access your panels.

    Solar Panel Cleaning Checklist

    In general, you need the following tools to clean your solar panels:

    • A non-abrasive cleaning tool such as a soft brush or a squeegee
    • A water hose
    • A telescopic extension pole, in case you need to reach solar panels on a roof

    If you are not comfortable cleaning your panels on your own, contact your solar installer for professional panel cleaning services.

    Step-by-Step Guide to Cleaning Solar Panels

    You can clean your solar panels more efficiently by following these steps:

    Brush Away Dried-Up Dirt and Residue

    Washing your solar panels is quick and effective when they are not very dirty. However, spraying water is counterproductive when there is a lot of dust and grime. Water and dirt create mud when mixed, which will dry up on your panels. Use a soft brush to remove dried-up dirt, bird droppings and other debris when your panels are dry.

    Wash Your Panels with Clean Water

    Once you have cleaned dried-up dirt and debris, you can wash your panels to remove any remaining dust and particles. Make sure your water supply is clean and avoid high-pressure nozzles. You do not need to wipe your panels dry since the water will evaporate on its own.

    Remove the Remaining Dirt

    If your solar panels are very dirty, brushing and washing may not be enough to clean them completely. You can scrub trouble spots with water and normal soap, but avoid detergents and other strong cleaning agents.

    Maintaining Your Solar Panels Between Cleans

    Solar panel maintenance not only involves frequent cleaning. You should also monitor energy production on a regular basis to rule out electrical issues. Many solar inverters include a monitoring app for homeowners, which you can use to track daily power generation with your smartphone.

    Low productivity is normal on overcast days since your solar panels are exposed to minimal sunshine. However, you should call your solar provider if the monitoring app shows lower-than-average electricity output on a sunny day.

    The Bottom Line

    The best residential solar panels have a 25-year warranty to cover product and installation issues but still need regular cleaning to stay productive. Dust buildup negatively affects panel efficiency, which can reduce your power bill savings.

    Do-it-yourself (DIY) cleaning is suitable if your solar panel system is installed on the ground or on a flat roof that you can easily access. If you have a single-story home with a pitched roof, you can also use an extension pole with a squeegee. Due to the risks involved, professional cleaning services should be used if you can only access your solar panels by climbing the roof.

    Suitable cleaning tools methods for solar panels include:

    • A soft cloth, sponge or brush
    • A squeegee
    • Washing with soft, non-pressurized water

    On the other hand, you should avoid these methods and tools:

    • Hardwire brushes
    • Roof rakes
    • Abrasive cleaning tools
    • Hard water
    • Chemical agents

    Solar panels have a high upfront cost, and protecting your investment is important. A solar panel system typically costs 2.85 per watt or 17,100 for a 6 kilowatt (kW) system, and the 30% federal solar tax credit reduces your total to 11,970. With those figures, you can expect a payback period of around 8.5 years. When you combine a 25-year warranty and regular cleaning, you can utilize your solar panels for over a decade after paying off your system.

    How to Clean Solar Panels on Your Roof?

    One of the most common questions for homeowners is how to clean solar panels on their roofs. Although solar panels by and large come with self-cleaning technology, they require some cleaning and maintenance to keep them working effectively. Solar panels are a great investment in your home and enabling them to work at their optimal efficiency will make them worth it in Ireland.

    In most cases solar panels are self-cleaning but in some situations such as dust accumulation and bird droppings, they need to be cleaned manually on a regular basis. If you have a roof mount system, it is usually safest to get your panels cleaned by a professional. Unless you have the right equipment to safely clean your panels, it’s best not to attempt doing it yourself.

    Why is it Necessary to Clean Your Panels?

    In general, when your solar panels get dirty, you can expect up to a 5% loss of output. This is because dust and other droppings may prevent the solar cells from absorbing energy at their optimum level. Most solar panels are positioned at an angle that will enable dust and grime to glide off easily. However, it’s certain conditions, manual intervention is required.

    When you purchase new solar panels for your home, you may want to look for a cleaning service as part of your agreement. You can ask your installer if this can be an added benefit to your contract. Although it’s fair to assume that rain washes away dirt from the panels, it’s not always the case. Even though there are grants available in countries such as the UK and Ireland to become affordable, they are still a big investment to make and taking proper care of the panels will give better output.

    While cleaning the panels yourself might seem like a great idea, it may not always be the case especially if you have a steeply slanted roof. It is not only risky for your panels as they may get damaged or cracked but also for your safety. There are also some that think investing in a professional solar cleaning service may not be worth the cost, so this is a decision to make based on your living conditions and the safety of doing it yourself.

    How Often Should You Clean Them?

    It is advised to clean solar panels anywhere between once a month to once a year. If your panel system is ground-mounted it is much easier for you to monitor the cleanliness of your panels. On the other hand, roof-mounted solar panels are a bit tricky to monitor on a regular basis.

    often than not, the angular position of the panels should help in them getting cleaned naturally through rainwater and wind. Another important factor in determining how to clean solar panels is the location. If you live in a crowded city area, you may want to clean your panels more often as compared to a house in the outskirts where there is less pollution and dust in general.

    A quick weekly or monthly check would be ideal to make sure your panels are performing without hindrances. According to source, an annual solar panel cleaning routine has proved to improve energy output by 12% higher.

    How to Clean Solar Panels Without Damaging Them?

    How to clean solar panels effectively? When you choose to install solar panels you are making a fairly big investment towards renewable energy and a greener lifestyle. A small effort in cleaning and maintaining your solar panels can go a long way to make sure the panels are working at optimal efficiency. Here are 10 cleaning tips that you need to know:

    • First and foremost, you need to check your panels for dirt and dust and see if they have accumulated in any of the panels, since this can block the panels from absorbing sunlight.
    • Never use a regular sponge or soap to clean the panels. You will end up damaging the glass of the panel. If you’d like to give the panels a proper wash, you can use a biodegradable soap with a soft rag.
    • Roof mounted solar panels are not very safe to climb up and clean, and therefore, it is recommended to call a professional who has the right equipment required. If you choose to clean the panels yourself, you must make sure to use safety ropes and ladders as the panels can get slippery while washing.
    • If you would like to clean your panels frequently, you could use a hose and run them along your panels to remove any dust on a weekly or monthly basis.
    • Make sure to not use any harsh cleaning materials on your panels as they can scratch or damage the panel glass, which can be a costly repair.
    • One of the most common tips on how to clean solar panels is to do it early in the morning. At this time the panels are cooled through the night, and with dew and mist on the panels will make it easier to clean the dirt and grime.
    • In most cases, using plain water to clean the panels is the most effective and safest way to clean them.
    • If you would like to use something more than water, make sure it is mild and does not contain harsh chemicals. A mild dishwashing detergent diluted in water should work well for this purpose.
    • If your panels are floor mounted it is way easier to do a DIY cleaning as compared to roof mounted panels which can be risky.
    • Do not use a washer spray on your panels as their pressure can damage the panels and hinder them from working effectively.

    Solar Panel Maintenance Tips

    Good maintenance with regular cleaning can increase your solar panel efficiency in general. Check your system regularly and document day to day performance to keep track of the panel performance and maintenance requirements.

    People who do not enjoy regular cleaning can install automated sprinkler systems or schedule regular cleaning appointments with local professionals. How to clean solar panels has never been easier with multiple options to choose from. Fortunately, solar panels are immovable and are comparatively lower maintenance systems.

    So, in general, taking regular care and monitoring your system’s performance and functionality should help a great deal in protecting your solar panel system. If you’re a DIY person and do not want to spend a lot on regular cleaning appointments, you can easily clean the panels by using these tips.

    How to Clean Solar Panels – Is it Worth it?

    In this article, we’re talking about a subject that is too often overlooked with solar panels – cleaning them. Keeping your solar panels clean can increase their effectiveness over time, but you have to be sure that you clean them the right way. We’ll walk you through the process step-by-step.

    Why Do You Need to Clean Solar Panels?

    The topic of cleaning solar panels is a sensitive one among solar panel owners. Some will tell you that it’s completely necessary, while some claim that rain will simply wash away any problems that the panels may encounter.

    The answer is somewhere in the middle. Solar panels don’t need to be cleaned, but you will be sacrificing some efficiency by not cleaning them. And while rain will certainly wash away certain substances that accumulate on the panels, it won’t be as effective as a manual clean.

    Generally speaking, the dust, dirt, pollen and debris that accumulates on solar panels has the potential to decrease the efficiency of a solar panel by roughly 5%. This isn’t a major difference, but depending on the size of your solar power system, it can add up. And if you live in an area where it rarely rains, or where it’s particularly dusty and dirty, this effect can be magnified.

    The bottom line is that your panels may need a good cleaning from time to time. So, if you want long-lasting panels operating at max efficiency, then you might consider giving them a good clean. Here’s how to do it:

    How to Clean Solar Panels

    Cleaning solar panels, for the most part, is not that difficult. The most difficult part might actually be having the tools to reach the entire surface area of the panel, and this will depend on how big your panels are.

    Depending on the extent of the mess on your panels, you might not need to do much to wash them. This is why we recommend that you first evaluate the panels. Check them out, and see the extent of the debris, dirt, and substance build-up on the panels (are there sticky substances such as bird droppings?).

    From there, decide how to clean the panels:

    For Minimal Dust Build-Up: Use a Hose

    If your panel’s messiness is mostly just dust and dirt build-up, then you likely won’t need more than a simple hose-down to get them clean and tidy. A garden hose should do the trick, provided it can reach your panels. Simply spray them down fully, and you’re good to go. You can let them dry off in the sun.

    Just be sure that you don’t spray the panels with high-pressure jets, or with a pressure washer. This might scratch or damage the panels themselves, which can lead to lowered performance and efficiency.

    For Extensive Mess: Scrub Them Down

    If the mess on your panels is more than just dust and dirt, and includes sticky substances such as bird droppings or sticky plant materials, then you might need to give the panels a good scrubbing.

    Once again, you don’t want to be too hard on the panels. Pick a soft scrubber, squeegee, or brush, that won’t scratch or damage the panels. Also pick a very mild soap, that doesn’t contain any chemicals which could harm or degrade the panels.

    From there, here’s how you clean the panels:

    • Fill a bucket with warm water and add a small amount of mild soap.
    • Rinse solar panels with a hose, or with another low-pressure sprayer.
    • Use soapy water and the scrubber to gently scrub the panels and clean them of any debris or buildup.
    • Rinse solar panels thoroughly to remove any soapy water.
    • Allow panels to dry in the sun.

    And there you have it, it’s quite the straightforward process, and doesn’t require much beyond a scrubber that is capable of reaching across your panels. But remember, solar panels get very hot on sunny summer days. You might want to schedule your clean for early in the morning or late in the evening.

    Another Option: Have them Serviced

    Another option, if you don’t feel like doing the work yourself, is to have the panels serviced by a professional. If you purchased directly from a solar panel company, then check the manufactures website to see if there are providers in your area that can have them serviced.

    Many companies offer service plans upon purchasing the panel itself. These plans (depending on the provider) might include regular maintenance and upkeep. They might also include regular checkups to ensure that the panels are running as efficiently as they should.

    But if it were up to us, we wouldn’t choose this option. These services might end up costing you a fair bit. You’re essentially spending money so that you can save on your electricity bill down the line. You’re cancelling out your own cost savings! And since cleaning solar panels isn’t a very difficult task to begin with, we’d recommend against hiring someone for this job in most circumstances.

    Remember, you’re essentially comparing the cost of servicing the panels against the cost you’d save by generating more energy with cleaner panels. These costs will rarely offset.


    Thanks for reading through our guide to cleaning your solar panels. We wanted to not only help you clean your solar panels, but also to help you decide when it’s actually necessary to clean your panels. Solar panels are strong and resilient, and might not need as much upkeep as you think.
