By keeping your solar panels in good condition, you can expect them to work optimally, stay free of any safety hazards, and continue to provide energy to your home or business for many years to come. This piece addresses the most pressing concerns about solar panel maintenance like does cleaning solar panels make a difference or not. We will go over the most common sources of dirt, how to properly clean your solar panel, and Is it OK to hose off solar panels, and whether is it necessary or not.
Does Cleaning Solar Panels Make a Difference?
If you have solar panels placed on your home, you must keep them clean in order for them to function properly. Dust, dirt, and leaves can all build up on the panels, preventing sunshine from reaching the cells. This has the potential to cut the quantity of electricity generated by the panel by up to 60%.
While it is critical to keep the panels clean, it is also critical not to harm them while cleaning. Because panels are commonly found on rooftops, it is best to leave it to the experts. Harsh chemicals and abrasive cleaning can both harm the panel’s surface. Solar panels should be cleaned with a gentle brush and a mild soap and water solution.
Cleaning solar panels is not a difficult or time-consuming job, but it must be done on a regular basis. Cleaning costs vary depending on the size of your system and the number of panels. Most Hunter Valley homeowners, on the other hand, can anticipate spending around $200 per year on solar panel cleaning.
Do Solar Panels Work Better if They are Clean?
Solar panel cleaning is critical to their long-term function. Solar panels should be cleaned as often as possible to prevent degradation, which can result in lower energy production and higher maintenance costs. Here are some of the advantages to know do solar panels work better if they are clean.
1. Increase Productivity
Solar panels generate energy by converting light. Dirt on the surface of the solar panel can reduce the amount of light absorbed by that region, lowering efficiency. Cleaning solar panels remove dust, debris, and other contaminants such as leaves and bugs, which can decrease efficiency even further. Regular maintenance will also remove any dirt or dust build-up on the surface of your solar cells, which would otherwise continue to decrease their efficiency over time.
2. Warranty
When you buy a solar panel system, you normally get many years of warranty coverage typically 25 years or more but this coverage isn’t always enough if something goes wrong with one of your panels during this time (for example, if there is a power outage). Maintenance of your solar panels, including routine cleaning, can increase the length of time they are covered by their warranty and increase the likelihood that they will continue to generate electricity for your home in the event of a problem.
3. Improve Longevity
Cleaning your solar cells will extend the lifespan of your system. You can also use cleaning products to protect them from dust and debris that could cause harm over time. Furthermore, you can use these products for cleaning tasks outside the house because they work just as well on wood, asphalt, and concrete.

4. Increase Return Time
One of the primary advantages of cleaning your solar panels is that it will increase the return on investment (ROI) time of your system. Many variables must be considered when deciding which solar panel system is best for you. One factor to consider is how long it will take before you see a return on your money. Cleaning solar panels provide an added benefit because it reduces the time necessary to see results with less work than if they were not cleaned properly in the first place.
Yes, Solar panel cleaning services help to increase effectiveness by removing dirt, dust, and other debris that can accumulate on panels and prevent sunlight from reaching the solar cells. Furthermore, regular cleaning can aid in the prevention of the growth of moss and other growths that can reduce the amount of sunlight that enters the cells.

What Happens When a Solar Panel is Dirty?
As discussed, does cleaning solar panels make a difference or not? Let’s now see what happens when a solar panel is dirty. Dirty Solar Panels are not only unsightly, but they also reduce the efficiency of your Solar PV System. As bird droppings, dust, pollution, and tree sap accumulate on your panels, sunshine no longer reaches the solar cells. In essence, dirty screens have the same effect on a Solar PV System as shading.
If your Solar Panels are connected in a string array, having just one solar cell coated in the dirt will result in inefficiency, affecting the overall performance of your Solar Panel System. Having an impact on both your green energy generation and your yield on investment. By keeping your solar panels spotless, you can ensure that your solar generation is always at its peak.
Can Water Destroy Solar Panels? Is it OK to Clean Solar Panels With Water? Can you Pressure Wash Solar Panels?
Cleaning your solar panels is usually a professional job, particularly if they are roof-mounted panels. This is due to the difficulty in gaining secure entry to your Solar Panels otherwise. Another factor to consider is that if you damage your Solar Panels in any manner, your warranty will most likely be voided.
Because solar panels are waterproof, hence it’s safe to say yes to whether is it Ok to clean solar panels with water. the rain will not harm them. In reality, rain is beneficial because it washes away some of the dirt and debris that accumulates on the panels over time.
But can you pressure wash solar panels? Although pressure washers are useful for cleaning the exterior of your house, including the roof and gutters, they should never be used on solar panels. Yes, their long reach and high pressure make cleaning large sections of solar panels much simpler, but doing so risks damaging the panels.
However, if you are wondering if can water destroy solar panels then no. You can simply use water and a soft, non-abrasive sponge or cloth to clean away grime and debris for optimal results and to avoid scratching your solar panels. To avoid leaving residue, dry with a squeegee or chamois, just as you would with glass windows or when washing your vehicle.

Does Rain Clean Solar Panels? Is Rain Enough to Clean Solar Panels?
If solar panels are not cleaned once a month, they can lose up to 30% of their energy output per year. But does cleaning solar panels make a difference or not? The output of your system may be reduced if your solar panels are coated in dust, filth, or grime. This reduces efficiency because the sun is obstructed. As the question suggests does rain clean solar panels? Well, Rain will suffice to clean your solar panels as long as they are not completely flat.
Rain will provide a light rinse of any loose debris or grime. It will not, however, remove baked-on dirt or algae, moss, or lichen that can cover your solar cells. So Is Rain Enough to Clean Solar Panels is not really a yes. This can result in a 15-20% decline in the energy output of your solar panels over time.

Is it Ok to Hose Off Solar Panels?
Dust, dirt, pollen, bird droppings, and leaves can all reduce the efficiency of your photovoltaic system. A thorough cleaning can significantly increase its efficiency.
Natural rainfall will often wash away dust or dirt particles, but you may still need to assist it with your outdoor hose. So, let’s see Is it OK to hose off solar panels or not.
1. Completely Shut Down Your Device
Before cleaning, your system should be fully shut down according to the shutdown process outlined in your user manual or the operating manual provided by the manufacturer of your inverter. DC systems must be fully shut down. The AC systems should be turned off using the Solar Power Main Switch.
2. Disconnect or Close Any Rainwater Gathering Systems or Gutters
If you have rainwater tanks installed and connected to your guttering system, have them briefly disconnected or turned off from the gutters to prevent dirty water from entering your tank.
3. Choose a Time of Day that is Calm and Mild
The mix of hot glass on your panels and cool water can increase the likelihood of cracks caused by a sudden temperature shift. Furthermore, if the hot sun is beating down on the panels, any water you’ve used may evaporate rapidly and leave dirty stains, undoing all of your hard work.
4. If Feasible, Clean Your Panels from the Ground
If feasible, clean your panels from the ground for safety reasons. Direct water onto your surfaces with a hose. Allow the stream of water to reach the panels by using a hose with an appropriate nozzle.
5. Make Certain that Water is Only Directed Onto the Top of Your Solar Cells
While some water should hit the back of your panels, you should not direct water onto the back of your panels or into the gap between your panels and your roof.
6. Use a Soft Towel and Mild Soap to Remove Obstinate Grime
You don’t need any fancy cleaning products; just water and mild soap will suffice. The best instrument may be a soft brush and squeegee with a long extension, a plastic blade on one side and a cloth-covered sponge on the other, and a sturdy base.
7. Do Not Try to Climb on Your Roof Unless You Have the Necessary Safety Equipment
Using water increases the danger of working on your roof. When water is used to clear the roof, it can become quite slippery. If it is not possible to clean your panels from the ground, do not try to access your rooftop unless you have the necessary safety equipment and training. Instead, for your safety, employ a suitably qualified professional cleaner.
Solar panels are an excellent method to reduce your carbon footprint while also saving money on your utility bills. Solar panels, on the other hand, can lose effectiveness over time due to dirt and debris. Get Coalfields to clean your house on a regular basis to improve the energy efficiency of your solar panels and make your investment last longer.
