Solar Panel Maintenance: Essentials and Important Details

Choosing the right time for home maintenance is complicated for many property owners; arranging it effectively doubles the challenge. While exterior cleaning is generally considered a must, many homeowners struggle with solar panel maintenance: whether they need it, how often, and how to do it. 

In this review, expert cleaners will share many useful details that are essential for proper solar panel maintenance, as professionals do. However, if you are too busy to do this cleaning routine alone, you may always request professional assistance in this and many other instances. 

Essentials Impossible to Neglect

If you do so, this negligence may result in substantial damage. If you want to ensure proper solar panel cleaning, follow these approaches tested and verified by professional cleaners:

• It’s best to use 100% deionized water. This water lacks salts, minerals, and other contaminants that may cause even minor deposits on the surfaces of solar panels. It will also ensure the absence of spots and streaks on the solar panels. Beyond excellent cleaning results, this water overall helps to maximize the follow-up energy production. 
• It’s best to apply roof cleaning techniques. The latter are the most effective and safest ones for solar panels. By moving from top to bottom and overlapping the streaks slightly, you can clean the surfaces fast and maximize effects.
• Don’t apply chemicals. They may significantly damage solar panels or even permanently disable them. Thus, use eco-friendly cleaning solutions instead and always clean them gently.

Proper solar panel cleaning is crucial to maximizing energy production and ensuring a faster return on investment in the long run. This cleaning routine can increase energy production by 30%. Professional cleaning leaves no chance for even the most solid dirt, moss, and bird droppings, especially when solar panels are located on the roof. Beyond that, regular solar panel maintenance also helps to extend their lifespan. 

Special Occasions

There are several challenging occasions when professional involvement is desired. During the spring season, the dust and pollen accumulate fast and on a large scale. A quick rinse will never solve the situation fast because of the streaks left. That’s another situation where applying the roof cleaning technique is the single feasible solution.

Wildfire seasons represent another cleaning challenge at all times. Moreover, the add-on layer is sticky and corrosive when it mixes with fog and morning dew.

Both cases add another layer of difficulty to cleaning, encouraging many property owners to request professional assistance in both instances. If you opt for the DIY approach, make sure the solar panels are cool before cleaning. 

Overall, start cleaning only after the completion of triggering events. Whether those are nature-related or originate from construction works, the consequences have to be addressed as soon as possible. 

Best Time to Clean Solar Panels

In this instance, it is best to review several aspects: seasonal and time of day. When reviewing the season, it is best to stick to the following timelines:

• Late winter and spring. It is best to prepare your solar panels for the next season and clean them somewhere between February and March. The best time to do this is when the temperatures are moderate. Regardless of the specific season chosen, professional cleaners advise against DIY cleaning when the temperature is high. It may cause thermal shock for solar panels because of the contrast between the outer high temperature and the cold water.
• Later summer and fall. The best months for this cleaning routine are August and October. Winds during the hot summer time often create a layer of dust on solar panels, decreasing their energy production considerably. Once summer is almost over, it’s time to refresh solar panels.

When considering the time of the day, the following recommendations from professionals are helpful:

• Early morning. It’s the best time for solar panel cleaning before they heat up. Addressing this issue in advance will prevent any thermal shock for solar panels, prolonging their lifespan. Cleaning solar panels during this time of day also helps to reduce glare.
• Late afternoon. The same effects are relevant at this time. Still, cleaning during this time may result in some areas being missed and streaks left. However, the surface of solar panels will not suffer as well.

If any of the highlighted timelines don’t work for you, feel free to request a quote for professional assistance. Expert cleaners will arrive at any time and complete the cleaning process shortly. 

How often Should You Clean Solar Panels?

The exact answer to this question varies depending on the specific setting. Experts advise assessing the actual state of solar panels instead of relying on seasonal considerations. Beyond that, pay attention to these highlights:

• Standard suburban areas. It’s a typical case when solar panel cleaning is required every 4-6 months. 
• Near construction sites. Clean your solar panels every 2-3 months. However, the exact recommendation depends on the intensity of construction works nearby.
• Near open lots, dirt roads, and hills. It is recommended to clean solar panels every 2-3 months because of the high dust exposure.

Bottom Line: Why Professional Solar Panel Cleaning Matters

Cleaning solar panels regularly is not just about aesthetics. It is more about energy efficiency, which will impact your bills. Once the solar panels stop operating properly due to dust and other residue accumulated on their surfaces, their effectiveness decreases significantly when property owners fail to clean solar panels accurately and carefully. Even one mistake can affect their productivity. In addition, these devices are prone to damage. 

Overall, cleaning solar panels is time-consuming and resource-intensive. It also requires great precision and attention to detail. Under these terms, professional solar panel cleaning ensures a big difference. It will impact your schedule by saving your precious time. It will also enhance the appearance of solar panels, making them shine. If you are too busy to complete it alone or lack skills, ask professionals to help you anytime!
