What To Wash Solar Panels With

Use A Soft Brush Or A Sponge

How to clean solar panels

When cleaning solar panels it is essential to use the right cleaning equipment. The glass is strong but using abrasive materials can scratch the surface of the glass, reducing its performance or even damaging the module.

If your solar panels are installed on the ground, then you can opt to use a simple sponge to clean them up or a soft brush as well. However, if they are located on the roof, then you must use a soft brush coupled with a long extension to make the work easier and safer from the ground.

Clean Solar Panels From The Ground

For safety reasons, its also wise to clean your panels from the ground if possible. A good quality soft brush and a squeegee with a plastic blade on one side and a cloth covered sponge on the other coupled with a long extension can make for the perfect tools allowing you to stay on the ground. Use a hose with a suitable nozzle to allow the stream of water to reach the panels.

NOTE: If cleaning your panels from the ground is not possible, do not attempt to access your rooftop unless you have the appropriate safety equipment and training. If you dont, hire a suitably qualified professional instead we are more than happy to connect you to our team of trusted professionals.

Spray Them With A Hose

If you live somewhere with a lot of pollen, sandstorms, or ash, you will want to wash your panels with a hose. Go outside, get a garden hose, and use a nozzle attachment to spray water on your roof to rinse your solar panels. Once you are finished, let them air dry. If you have a flat roof and your panels are unclean, you can clean them with warm waterand a soft cloth-covered sponge or squeegee.

However, unless you have a harness or a roof anchor, you will not want to clean your roof if it is pitched. If you want the panels to be clean, you might then want to hire a solar panel cleaning service.

When the weather is particularly hot and sunny, avoid washing your panels. To keep the panels from experiencing rapid temperature changes, you can either clean them in the early morning or wait for an overcast day.

How To Keep Solar Panels Clean

Here are a few tips on keeping your panels clean, so that they can keep running efficiently:

  • You should do a visual inspection monthly to look for any buildup of dust and any dirt.
  • If you cant do a deep clean, try scrubbing your panels with a light sponge or gentle cloth at least once a month or so.
  • If you reside in the western United States, where wildfires occur annually, you should inspect your soot and ash buildup panels after any major fires.
  • Monitor your bills or solar statements for any drop inefficiency. Changes can mean that the solar panels need cleaning.
  • If you live in a campervan, clean your panels after visiting a dusty location, such as the desert.
  • When the panels are installed, ensure that they are put in an angle that will favor self-cleaning for easy maintenance. I recommend installing them at a 35-degree angle or more. This makes it harder for debris, like leaves or twigs, to accumulate on top of the panels.
  • Hire a professional to do a deep clean if your panels are particularly dirty.

Dealing With Oily Stains

Oily stains can occur in some installation scenarios, such as if you live near an airport and are under a flight path or if you live adjacent to and downwind of a major roadway frequented by trucks. If oily stains start appearing on your panels isopropyl alcohol can be used as a spot-cleaning substance..

When To Clean Solar Panels

Solar Panels are designed to be self-cleaning in the UK, and as such would be deemed to have little to no maintenance at all. In certain situations, such as having panels in a particularly dry area or where the panel tilt is less than about 5 degrees, cleaning is recommended to ensure an efficiently generating system.

Safety Rules To Follow While Cleaning Your Solar Panels

Although solar system installation doesnt have a lot of mechanical parts, safety should be your first priority when cleaning solar panels. Below are a few safety rules to follow when attempting solar panel cleanup.

  • Dont clean solar panels on your roof during bad weather i.e strong wind storm or heavy rain
  • Avoid using solar panels as a way to secure your position on the roof
  • Make sure the roof surface is dry and non-slippery
  • The roof must be strong enough to bear your weight
  • Always wear required safety gear including gloves, helmet, hard shoes, and face mask
  • While cleaning the solar panels, dont work alone. Ask one of your family member or friend to stay close to you while you are performing this task

Cleaning solar panels on your house should be done safely and carefully.

For More 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 dont want to be too hard on the panels. Pick a soft scrubber, squeegee, or brush, that wont scratch or damage the panels. Also pick a very mild soap, that doesnt contain any chemicals which could harm or degrade the panels.

From there, heres 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, its quite the straightforward process, and doesnt 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.

Avoid Using Water With High Mineral Content

Module manufacturers recommend the use of distilled or de-ionized water to clean solar panels. Mineral-rich water may leave deposits of particles over time and its chemistry is not recommended for the glass of modules.

If you do not have access to de-ionized or distilled water, you can use a water-softening hose attachment to filter those minerals.

    How Do Solar Panels Work Solve The Energy Crisis With Clean And Efficient Photovoltaic Cells

    Have you ever asked yourself how solar panels work? Solar energy is the energy springing from sunlight that has been converted into energy useful to us humans. Solar power can be used to heat our homes, to small power appliances, to water swimming pools, and even to run our cars. There are many different places solar power can be applied, from rural areas to large cities. Lets take a look at how solar panels work.

    The sun provides us with countless numbers of different types of renewable energy. It is responsible for renewing the oxygen in our atmosphere, converting light into other forms of energy we use every day, and is responsible for heating our earths surface. Solar power is a valuable source of renewable energy because it has no pollution associated with it. Solar energy can also be used to heat our homes, to small power appliances, and to power our cars. All of these things can provide electricity for a much smaller home and maintain the lights on at the International Space Station.

    Solar Panel Cleaning Guidelines

    Solar Power plants are essentially maintenance free as they do not consist of any moving parts. However, panel cleaning is one aspect of solar panel maintenance that should not be taken lightly. When Google conducted a groundbreaking experiment at their 1.6 MW solar farm in Mountain View, California, it was found that solar panel cleaning was the number one way to maximize the energy they produce. Cleaning solar panels that had been in operation for 15 months almost doubled their output of electricity .

    Can You Use A Pressure Washer To Clean Solar Panels

    No, using a pressure washer to wash solar panels is not advisable at all. This is because the pressure might force water into the panels junction box or the solar plugs that are not sealed well and exposed wires. Generally, it is recommended that even when using a hose, the pressure should be maintained below 40bar.

    Materials And Methods For Cleaning Solar Panels


    If the panels are dry, before tackling the modules with water, brush off any loose materials first this will make cleaning easier and faster.

    Dont use metal objects or harsh abrasive products for removing caked on materials. Scratching the glass on a solar panel can affect its performance as scratches will cast shadows. Avoid using detergents if possible as these may streak the glass of the panel. Use of abrasive powders also risks scratching the panels.

    Given the nature of good quality solar panel glass, clean water and a little scrubbing with a coarse cloth covered sponge or soft brush should remove the most stubborn grime. Plastic scourers may also be used.

    If your mains-supplied water is hard and rainwater is available use that as a final rinse then squeegee dry. If hard water is all you have, just be sure to squeegee well as mineral-ladened water can form deposits on glass as it dries.

    How to Wash Solar Panels Properly: 9 Best Practices ...

    A lot of individuals presume solar panels cleaning to be a hassle. The assumption is also that panel maintenance demands a lot of your time and effort. We, at SunEdison, are here to help break that myth for you.

    In this blog, we cover quick tips on how to keep your solar panels clean. These will be time saving and help aid in the maintenance of your panels. Do solar panels need cleaning? Yes. Depending on the type of panel you have and the dust / pollution in your area, you might have to clean your panels on a weekly or fortnightly basis.

    Quick Tips:

    • Do not overclean your system. Unless there is a significant amount of dust in your area, a weekly cleaning should suffice.
    • The best time for cleaning the panels is early morning or late evenings. During the peak hours, not only are the panels too hot, you may also lose significant generation. Also, if cleaned during peak hours, the glass becomes very hot, and spraying water on the hot glass can cause thermal stress and break/damage the glass eventually.

    Do I Need To Turn Off My Solar Panels To Clean Them

    Yes, to safely clean your solar panels it is recommended that you turn them off before doing so. Use your specific manufacturers manual to learn how to correctly and completely turn off the solar panel system before beginning your cleaning. Once this is done, begin cleaning the solar panels by lightly brushing off any loose dust and buildup before cleaning the solar panels with water and a soft brush.

    How To Gauge When Its Time To Clean Solar Panels

    The most obvious way to tell when solar panels need cleaning is when the efficiency of the system begins to decline.

    Pollution is typically higher during the winter when cold air traps pollutants closer to the ground than the warmer air of summer. That means spring is the best time of year to clean solar panels, as they become too hot to touch during the summer. The best time of day to clean them is in the morning or early evening when they are cooler.

    There are companies working on ways to use advanced technology to monitor the condition of solar panels and remove some of the guesswork.

    Researchers in Spain have received a patent for a solution that attaches a sensor to the glass surface of a panel and uses an LED light to measure the amount of dirt that has built up. The US National Renewable Energy Laboratory is also developing a way to monitor the amount of electricity panels produce every day to detect when soiling has begun to degrade output.

    Ecoppiaâs cloud-based platform uses sensors and machine learning to monitor a solar PV system, collect weather data, and travel across trackers to clean panels on an optimized schedule.

    How Does Extreme Weather Impact Your Solar Panels

    Solar panels are made for durability, which means you can keep on using them for years to come. Best of all, theyll keep performing at peak efficiency even after years of wear and tear, thanks to their advanced design. This includes rain, wind, snow, and even hail. Not only that but theres evidence that they survive hurricanes, with places experiencing hurricanes having little damage to their solar panels.

    However, they are not 100% indestructible. On rare occasions, thin-film photovoltaic panels can suffer damage due to extreme weather conditions, such as hail, hurricanes, tornadoes and lighting. This is why you should take advantage of a good warranty and/or have your solar panels insured by your homeowners insurance policy.Panels are affected by the weather, mostly with regard to heat. If it gets too hot, a reduction of 1% per degree will occur. However, if you lift the panels off the roof or ground, this may prevent overheating and keep them cool, thus maintaining their production level.
