Clean Solar Panel: How Often & How Much to Cost
As the adoption of solar energy continues to rise, ensuring the optimal performance of your solar panels is crucial for maximizing energy production. One of the key maintenance tasks for solar panel owners is regular cleaning, yet many are unsure about the frequency of cleaning and the associated costs.
In this comprehensive guide, we will unravel the importance of cleaning your solar panels, delve into how often they should be cleaned, and provide insights into the costs involved. By the end of this article, you will have a clear understanding of the best practices for maintaining clean and efficient solar panels while managing your budget effectively.
Understanding the Significance of Clean Solar Panels
Solar panels are subjected to an array of environmental elements, including dust, debris, pollen, and bird droppings, all of which can accumulate over time and impede their performance. These deposits act as a barrier, diminishing the amount of sunlight that reaches the photovoltaic cells, ultimately leading to reduced energy production. If this build-up of dust, leaves, and bird droppings isn't addressed, it directly results in energy loss. In the presence of string inverters or micro-inverters on the solar panels, bird droppings can accumulate and interrupt the flow of current. While rain can help wash off some of these deposits, similar to a car left out in the rain for an extended period, your solar panels won't be spotlessly clean afterward.
Regular and thorough cleaning not only ensures that the panels operate at their maximum potential but also extends their lifespan, thereby safeguarding your investment in solar energy. A study conducted on dirty solar panels found that they can cause a reduction in efficiency of up to 5%, whereas a comprehensive cleaning regimen can enhance efficiency by up to 3.5%. Failure to carry out monthly cleaning can lead to a significant 30% energy loss per year. By maintaining clean solar panels, individuals can fully harness the benefits of solar power and contribute to a sustainable energy future.
How Often Should Solar Panels Be Cleaned?
The frequency of solar panel cleaning largely depends on the local climate, the presence of pollutants, and the angle of the panels. However, according to most experts, it is generally considered reasonable to clean solar panels on average every six months. While some regions may require more frequent cleaning due to high levels of dust or pollution, others with regular rainfall might experience natural cleansing. Determining the ideal cleaning schedule is essential for maintaining optimum energy output while balancing associated costs.
Can I Clean Solar Panels By Myself?
Although it's inevitable that dust and dirt will accumulate on your panels, the blessing of rain ensures a natural cleaning process. Even a brief, gentle rain shower can effectively cleanse the grime from your panels, allowing them to operate at their optimal capacity without requiring any additional effort or expenditure.
Research from the University of San Diego supports this, as scientists investigated the monthly energy production decline resulting from dust and grime during summer droughts. Their findings indicated that in almost all cases, the expense of hiring a professional to clean your panels is not justified. Nevertheless, there are a few specific circumstances where this may not hold true.
Factors to Consider When Cleaning Solar Panels
1.Different Types of Dirt
An additional factor to consider pertains to the nature of the debris that accumulates on the panels and its frequency. While common airborne particles such as pollen, dirt, and dust are easily washed away by rain, certain substances like bird droppings may prove more challenging to remove. Regularly monitor your panels before and after rainfall to assess their cleanliness. If persistent dirt remains, it might be wise to explore professional cleaning options.
2.The System's Placement
The location of your solar panel system is another important consideration when evaluating the need for cleaning. If your panels are situated near industrial areas, busy highways, or fields, and frequently exposed to airborne dust, they are likely to accumulate more debris than standard solar systems. In such cases, the financial benefits of cleaning may be more significant, particularly in regions with infrequent rainfall.
Cleaning Solar Panels Yourself vs. Hiring a Professional
Cleaning solar panels is an essential part of maintenance to ensure optimal performance. When considering whether to clean them yourself or hire a professional, several factors come into play.
1. Cleaning Solar Panels Yourself
Cost: Cleaning the solar panels yourself reduces immediate costs as you won't have to pay for professional services.
Regular Maintenance: It allows for more frequent and customized cleaning, especially in areas prone to dust and dirt accumulation.
Knowledge and Control: You have direct control over the cleaning process and can ensure it's done to your standards.
Considerations
Safety: Climbing onto the roof to clean the panels can be hazardous, especially for those without experience or proper safety equipment.
Effectiveness:Improper cleaning methods, such as using abrasive materials or harsh chemicals, can damage the panels and reduce their efficiency.
2. Hiring a Professional
Expertise: Professionals are equipped with the knowledge and tools to clean panels effectively without causing damage.
Safety: Trained professionals are adept at navigating the potential hazards associated with rooftop work.
Time and Convenience: It saves you the time and physical effort required for cleaning and provides peace of mind regarding the job's quality.
Considerations
Cost: Professional services come with a financial outlay, which may not be justified for those in areas with minimal panel contamination.
Frequency: Depending on the location and local environmental factors, professional cleaning might not be necessary as frequently as anticipated.
In conclusion, whether to clean solar panels yourself or hire a professional depends on various factors such as cost, time, safety, and expertise. It's important to weigh these considerations and choose the most practical option based on your specific circumstances.
How to Clean Solar Panels Yourself
Clean solar panels by yourself can save money. But before you started cleaning, there are something you need to know.
Firstly, get in touch with the solar installer to inquire about any specific system-related information or special precautions to consider before cleaning. Then, ensure that all necessary safety equipment is in place and being used correctly.
Use only a gentle stream of water from a garden hose, similar to rainfall. Applying any form of high-pressure attachment or a power washer is likely to cause damage to your solar panels, potentially leading to a substantial and permanent reduction in production while voiding your warranty.
It is crucial to avoid cleaning your panels with anything abrasive, waxy, or corrosive, as these substances could harm the panel's protective coating. In fact, one of our solar panel manufacturers recommends refraining from using any chemicals for cleaning – just water.
Additionally, it's important to note that solar panels can become very hot when exposed to direct sunlight. If you are determined to clean them yourself, opt for a day with overcast conditions.
How Much Does it Cost to Hire Professional to Clean Solar Panel
According to Thumbtack, the average cost for a residential cleaning project stands at $133 nationwide.
Factors such as location, the quantity of panels, and accessibility (e.g., whether they are ground-mounted or on a second-story building with a pitched roof) will cause this figure to fluctuate. It's important to ensure that the cost of cleaning services will be recuperated through a reduction in your electric bill.
However, it's essential to note that the next rainfall is likely to naturally cleanse the panels, essentially eliminating any production loss caused by dirt and dust. Nonetheless, if persistent dirt such as bird droppings is present, professional cleaning might be necessary.
