How To Clean The Solar Panels

Clean solar 1

Solar energy can reduce your utility bills with just one month of usage. It's important to know, before you make an investment, what extra charges could crop up down the road. Clean solar panels are the primary maintenance necessary to keep them in good condition. Our intention is to teach you how to easily and inexpensively clean your solar panels in this short article.

Why should I clean my solar panels? Is cleaning solar panels worth it?

The efficiency of solar panels is negatively affected by various components, such as dust, dirt, pollen, bird droppings, and other debris.

Solar Panels That Haven't Been Cleaned or Rained On Can Still Make Money, Researchers found that panels that hadn't been cleaned, or rained on, for 145 days would waste only 7.4% of their efficiency.

The solar panels had twice as much electricity as before they were cleaned after operating for 15 months.

It isn't necessary to maintain solar panels since they don't contain any moving parts. It is still important not to skimp on cleaning when maintaining solar panels. How to clean solar panels the right way can be found in this article.

How to Clean my Solar Panels


To begin with, you should check with the manufacturer of your solar panels. Depending on their recommendations, they might recommend specific cleaning methods.

The heat produced by solar panels increases dramatically in direct sunlight. Take your solar panels outdoors in the mornings or afternoons, or choose a relatively cool day.

You might be able to resolve the problem just by using a garden hose. You might also need to give them a thorough cleaning if there is a lot of dust or dirt on them.

Warm water and soap can be mixed in a bucket or spray bottle, no special equipment necessary.

Use an old cloth or sponge to soften the solar panel's surface. Electrical wiring doesn't have to be cleaned under the covers.

If you must climb up on the roof in order to clean your solar panels, observe extra caution. If you are not confident that you can do the job safely, consider hiring professional solar panel cleaners.

Will neglecting Solar Panel cleaning cost me money? Do Solar Panels work when dirty?

The amount of power produced by your solar system will be affected by anything that stands between the panels and the sun. Solar panels typically reduce their productivity so little when dirt builds up on them that taking action is hardly ever worthwhile. However, if solar panels are not properly cleaned, they can lose 15-25% of their efficiency. 

In other words, you will have to purchase electricity from the utility company at their prices instead of generating 15-25% more electricity. The payback period will be extended by a couple years if this happens.

How Much Production Am I Losing with Dirty Panels?

You will only get so much electricity from your solar system if you keep anything between your panels and the sun. The losses from dirt buildup on solar panels are so small that they rarely make sense to even bother to clean them.

How often should solar panels be washed? Does cleaning your Solar Panels make a difference?

The spring is a good time to clean because most places are more polluted in the winter. Once-and-twice-a-year cleaning of solar panels results in a 3.5% and 5.1% increase in electricity production.

It is usually enough to clean panels every once in a while, although in some places they require extra  attention. The Sunshine State can be understood to be one of the wettest in the nation, but with its own unique climate. A 51-year analysis of the data from 48 weather stations in the state reveals that on average, 69 percent of the days in the year are rainless, or 252 days per year.

When compared to panels which are only cleaned by rainfall, annual cleaning can enhance energy output by as much as 12%.

A second example occurs when pollution-causing sources such as freeways, factories, and airports are installed near solar panels. It will also be necessary to clean them more frequently here.

Snow and leaves need to be removed in autumn and winter as well for best performance.

Make sure you consider the angle at which your panels are installed. If your solar panels are tilted, rainwater can clean them more effectively, so if your solar panels are flat, you might need to clean them more frequently.

In light of your frequency of cleaning, here's the best tip: monitoring the output of your panels before and after cleaning is key. Change the interval between time intervals. Analyse what works for you by taking note.

Is cleaning Solar Panels is worth the effort?

The following are the key takeaways:


  • Among the many factors that reduce the effectiveness of solar panels are bird droppings, dust, and pollution.

  • Your solar panels will produce less solar energy if they are dirty, increasing the length of time it takes you to pay back your investment.

  • Cleaning of your solar panels may be necessary if you live in an arid region or near a pollution source. You will also need to do so if your panels are mounted vertically.

  • Using solar output as a measurement tool, monitor it before and after cleaning; adjust the frequency accordingly.

As far as solar panels are concerned, they are not too unlike regular windows to clean. Additionally, it takes no time at all. This boost in performance could save you money on your power bills, as well as improve your system performance.

Otherwise, you are throwing money out of the window if you fail to clean your panels.

Some solar panel cleaning services, such as others offered through the company I recommend, are available for those not willing to clean their panels themselves.

What is the best way to clean Solar Panels?

You can clean your solar panels yourself by washing them with water, a mild detergent, and a soft brush. Be careful not to damage your solar panels with harsh chemicals, abrasive scrubbers, and pressure washers.

Can you use a pressure washer to clean Solar Panels?

To get the buildup out of the corners, you can use water and a gentle soap like dishwashing detergent. Be careful not to damage your solar panels with harsh chemicals, abrasive scrubbers, and pressure washers.

Can you use vinegar to clean Solar Panels?

The answer is yes! Solar panels made of glass are especially easy to clean when using natural cleaning products, such as vinegar. Add a little detergent or soap (12 teaspoons) to a solution of water (2 cups) and vinegar (¼ cups) to make an easy but effective cleaning solution.

Can I use Windex on Solar Panels?

Is Windex a suitable cleanser for solar panels? It is possible to use Windex for solar panels, but it will take some time because you must wipe them down with regular Windex. Rather than using an indoor Windex solution, opt for an outdoor solution.

Do I need to turn off Solar Panels to clean?

The user manual of your inverter manufacturer may provide an operating manual that explains how to shut down your system completely. Shutting down the DC systems is required. Switching off the Solar Supply Main Switch is the best way to shut down the AC systems.

Calling professional cleaners is sometimes a better and safer option?

Your review of the variables involved, your assessment of your available resources, and your conclusion that you will not be able to clean your solar panels on your own may have convinced you to approach this question differently. You may have realized, for instance:

You can't walk on your roof because it's too high, too steep, or too slippery.

It doesn't make sense to buy and store a bunch of equipment you may only use once per year if you don't own a ladder or adequate cleaning tools.

As a result of your physical limitations, you find it extremely challenging to climb ladders and scramble around on rooftops.

Is everything that goes into that extra work just too much for you to handle?

Professional cleaning is a great option for many solar customers. If you find that you need to have your solar panels cleaned, call the company that installed them to inquire about their  cleaning services. In addition to your roofing materials, pitch of your roof, and the square footage of your solar array, they should also have photographs or digital renderings of where your solar panels are situated on your roof. Once they possess this information, they should be able to give you a very accurate price estimate over the phone or at least suggest a source that can provide you with them.

Why should you hire a professional to clean your Solar Panels instead of cleaning them yourself?

You can inadvertently encourage dirt to accumulate on your panels when you use tap water or chemicals. Cleaning your panels professionally is one of the reasons you should do so. It will also help give you a better result with a longer-lasting impact if you use de-ionised water to achieve a spot-free finish that is more durable. A good professional cleaner will have one of these systems as a matter of course, but they tend not to be worth the investment for individuals who intend to use them only for window cleaning.

In addition to checking other aspects that can affect the health and functionality of your system, having a trained professional do the work can help you. The main concerns are potentially flammable materials, cracks, hot spots and nests from uninvited visitors like birds, rats and possums. Detecting issues like crazing (ie. webs of small cracks) and delamination (i.e. peeling off of laminate layer) are also essential to to ensure a system running well.

In addition to safety, hiring professionals means avoiding risky work on your roof. Wearing the right safety gear is essential. When you don't have the appropriate equipment or experience, you're likely to put yourself at risk and possibly become injured. (Plus, you're likely to run into wasps.)
