Did you know that in recent years, purchases of solar panels have increased at an unprecedented rate? With that increase in sales also comes an increase in solar panel cleanings.
The more popular solar panels become with homeowners, the more meticulous people are about their cleanups. While cleaning solar panels isn’t difficult, they just need a quick hosing down in the summer and fall to keep them clean, it still takes time.
Have you ever wondered what the answer is to the question “How often do you need to clean your solar panels?” We have the answer below.
This guide will teach you the benefits of cleaning your solar panels regularly, as well as how often to get the job done. Keep reading!
Why you should clean solar panels
Solar panels need to be cleaned periodically, depending on the environment in which they are installed. Regular cleaning of the solar panel surface is necessary to achieve optimum production from the system.
Areas with dirt, debris, smog, or bird droppings, should be cleaned at least once or twice a year. Solar panels in dusty or sandy areas may require more frequent maintenance.
Cleaning should always be done with a soft cloth or brush, and only with water or a mild detergent. It also helps them last longer. It increases your productivity, contributing to a cleaner and more sustainable environment.
Methods for cleaning solar panels
Solar panels need to be cleaned regularly, but there is no definitive answer on how often they should be cleaned. It usually depends on the location, the slope of the panels, the local environment and the amount of area covered by the unit.
In dusty or arid climates, it is suggested to clean the panels once a month or two, while dirty areas need less frequent cleaning. Here are some methods to clean and install solar panels.
Use a mild soap solution
Solar panels need to be cleaned every few months to keep them free of dust, dirt, bird droppings, and other debris. A mild soapy solution is an effective and gentle way to clean once you decide to go solar.
To cut scratches and prevent damage, use only mild cleaning solutions, such as a mild soap diluted with water or a mixture of vinegar and water. It helps dissolve any dirt or bird droppings that may have accumulated on the solar panels and can help prevent unwanted marks or stains.
Also, use only a soft cloth and wipe the panels in a circular motion to protect them from scratches. If a regular hose is used to clean the panels, make sure the pressure is low and only spot clean in a circular pattern, using the lowest pressure necessary.
Use soft clothing or brushes
Solar panels should be cleaned at least two to four times a year for optimal efficiency. Before cleaning your solar panels, you should inspect each module for signs of dirt and debris.
If necessary, use soft cloths or brushes to remove any foreign material from the surface, then rinse with clean water. Also, check the wiring to make sure there is no corrosion over time.
During the summer months, the panels should be inspected more frequently as moisture, dust, and debris can interfere with egress. Be sure to check your solar panel manufacturer’s user manual for specific cleaning protocols to ensure the safety and efficiency of your panels.
Let the panels cool completely
It is important to clean solar panels regularly to ensure optimum performance and get the most out of each panel. The best practice is to clean the panels at least twice a year, or more often if the panels are located in an area with a lot of dust and airborne particles.
Make sure you always cool the panels down before attempting to clean them, as this can cause severe damage to the panels or even cause a fire if done while they are still hot.
Also, be sure to use a mild cleaning solution and soft cloths or sponges so as not to damage the sensitive material on the panels. With regular and safe cleaning, you should be able to get the most out of your solar panels.
What happens if the solar panels are not cleaned regularly?
Regular cleaning of solar panels is vital to ensure they remain free of dust and debris. It continues to produce clean, efficient and reliable electricity.
Without regular cleaning, dust buildup on solar panels will reduce the amount of solar energy they absorb. It hinders the ability of photovoltaic cells to convert energy from sunlight into electricity.
Dust and debris buildup can decrease electricity output from solar panels, so it’s important to maintain them clean your solar panels and free of obstructions to ensure maximum efficiency. In general, solar panels should be cleaned every 6 to 12 months, depending on location and weather conditions.
If your panels are located within dry areas, such as deserts, they will need to be cleaned a little more regularly, as dust and debris can accumulate quickly. If they are also located in particularly polluted areas, they may need to be cleaned more frequently.
How to tell if your solar panels need cleaning
Solar panels must be cleaned quarterly to maintain optimal efficiency. Cleaning the solar panels more frequently in case of dust, ash or debris on the panels will benefit the amount of energy generated and keep them in good condition. In general, dirt and dust will not affect power output until they obscure 10-25% of the panel surface.
To tell if your panels need cleaning, look at them from a distance and note any irregularities that occupy the face of the panel. If there are visual obstructions such as dirt and dust, bird droppings, or tree sap, you should consider cleaning the panels thoroughly. Be sure to use a soft brush and cleaning solution to avoid possible damage.
