Investing in a solar system for the home is a great way to save on costly electric bills, though the initial cost of a solar panel system is often a deterrent. However, once the solar panels are installed the system is relatively low maintenance; just make sure to keep the solar panels clean in order to maintain the efficiency of your solar system.

Knowledgeable DIYers who have experience working on roofs can handle this task with relative ease, but for those who haven’t spent a lot of time on a roof, the risk is significantly higher. So how do you clean solar panels? Trained technicians who work as solar panel cleaners almost every day are best equipped to handle this job. Professional solar panel cleaners work at heights on a regular basis, so they know the protocols and best practices to follow in order to get the job done quickly and safely.

What to Consider When Choosing One of the Best Solar Panel Cleaning Services

There are a number of considerations to take into account before choosing one of the best solar panel cleaning services. In choosing the best one for one’s needs, a customer may want to primarily consider the service area. However, other factors include scheduling, licensing and insurance, additional services provided by the company, and customer support.

Service Area and Scheduling

Before looking at the various services a solar panel cleaning company offers, it’s necessary for customers to check the service area to make sure that their home falls within the given range. There are very few solar panel cleaning services that have a nationwide range, so it’s recommended to look for regional service providers. Once a customer has narrowed down the choices to their state or general geographic location, the next step is to ask about scheduling.

Many solar panel cleaning companies have flexible scheduling available, though there are some that may need to book an assessment appointment before scheduling a cleaning appointment. If this is the case, customers will want to ask whether there is a cost associated with the assessment or if this service is included in the final cleaning costs.

Licensing and Insurance

One of the more important aspects to consider when you are looking for a solar panel cleaning service is whether the company is licensed and insured. Keep in mind that solar panel cleaning experts need to work on the roof, putting them at risk of potentially life-threatening falls. In order to feel confident that your solar panel cleaning appointment can be completed with minimal risk, it’s recommended to find companies that train and employ licensed and insured workers.

Technicians may be trained by the solar panel cleaning company or they may receive certification by the North American Board of Certified Energy Practitioners (NABCAP), which specializes in certifying professionals in the field of renewable energy. While NABCEP certification isn’t required to be a solar panel cleaning expert, it does demonstrate an advanced level of knowledge and expertise in the renewable energy industry.

Additional Services

Solar panel cleaning companies are not typically limited to cleaning solar panels, so if a customer has other work that they need done around the home, it’s worth it to check the company website or ask the customer support staff to find out what additional services the company offers. To better provide for the needs of potential customers, many solar panel cleaning companies have a range of extra services, like wildlife remediation, window cleaning, gutter cleaning, pressure washing, or chimney sweeping.

Wildlife remediation typically involves making repairs to the solar system, building protective barriers to prevent birds and other animals from damaging the solar panels, and repairing any barriers that have gotten damaged since they were installed. Some companies may also be able to install gutter guards to prevent wildlife and debris from entering the gutter system.

Customer Support

During an initial scheduling call or email communication, customers can ask any questions about information or services that are not clear on the company website. Customer support staff shouldn’t have any issues answering questions promptly or obtaining the correct information for more technical questions about the job.

Customer support is the backbone of any service-based company. If the people that are hired and trained to speak directly to customers are not knowledgeable about the service or cannot answer questions about costs, scheduling, service area, licensing, or insurance, then this indicates a low level of experience and high employee turnover. It’s recommended to avoid companies with these red flags.

How We Chose the Best Solar Panel Cleaning Services

In order to find the best solar panel cleaning services, it was necessary to extensively research a broad range of potential options before being able to properly evaluate the quality of the services being offered. For each company, we considered key factors such as customer communication, service area, and any extra work the companies could handle outside of solar panel cleaning.

Very few solar panel cleaning companies offer a nationwide service area, so this list focuses on regional service providers that are based in the leading regions for solar energy use such as Florida, Texas, the Carolinas, and California. Additionally, clear, polite customer support is an integral part of providing excellent service to individuals, families, and businesses that want to have the solar system cleaned. With this in mind, companies that had an evident focus on customer support were selected over those with poor customer communication. Any extra services, like wildlife remediation, window cleaning, gutter cleaning, pressure washing, or chimney sweeping, also helped to improve the overall evaluation of a company.

Before You Hire One of the Best Solar Panel Cleaning Services

Consistent rainfall will wash away the majority of debris that has built up on the surface of the solar panels. But for homeowners who want to get the highest efficiency from their solar systems, cleaning solar panels is necessary. Regularly cleaning the solar panels can also help extend the life of the system by removing dust, dirt, animal droppings, and other debris that can bake onto the solar panels as they sit under the hot sun.

It’s important to note that while it’s a good idea to hire a solar panel cleaning service to quickly and effectively take care of a solar system, some homeowners will be able to tackle this job. However, if a homeowner doesn’t have experience working on a roof, or if the roof is steeply pitched, then it’s recommended to rely on trained professionals that can get the best results while staying safe.

Cost of Hiring One of the Best Solar Panel Cleaning Services

Given that solar panels only need to be cleaned about once or twice a year, this service is an affordable one that helps increase the efficiency of a solar system by about 5 percent. On average, homeowners can expect to pay about $100 to $350, though there are several factors that can increase the price of the job, including roof slant, home height, and system size.

Typically, solar panel cleaning services will charge about $3 to $10 per panel. Some companies may charge a flat rate fee for the cleaning instead of a per solar panel cost, but it’s important to speak to a customer service representative to find out the exact price and discuss any additional fees, such as annual inspection fees, which generally cost about $150 in addition to the cost of cleaning.

The Advantages of Using One of the Best Solar Panel Cleaning Services

There are many reasons it’s better to hire a professional solar panel cleaning service instead of trying to handle this work independently. Solar panel cleaners work in this field on a regular basis, which means that they are also much more comfortable than the average DIYer when it comes to climbing ladders, walking on roofs, and recognizing potential hazards.

Homeowners can also count on professional solar panel cleaning technicians to complete this work quickly and effectively. Their experience and knowledge not only improves the speed of the job, but the final results also tend to be better than if the same work was entrusted to an untrained DIYer. Similarly, experts in the solar panel services field can provide information or offer additional services to help solve ongoing issues.

  • Trained solar panel cleaners have more experience working at heights than the average DIYer.
  • Professional solar panel cleaning services work fast and produce great results.
  • Knowledgeable experts can help address ongoing problems with services, like wildlife remediation.

FAQs

Check out the informative FAQs below to learn how to clean solar panels on a roof, what professional solar panel cleaners use, and some of the cleaning methods to avoid.

Q. Is solar panel cleaning worth it?

One of the most common questions that gets asked about solar panel cleaning is do solar panels need cleaning? After all, if rain and wind can remove most of the dirt and dust, then why do solar panels need to be cleaned? Although precipitation can help to remove some of the accumulated dust and debris, it isn’t as effective as manually cleaning the solar panels. With annual solar cleaning, you can increase the efficiency of a solar panel system by 5 percent or more. This may not seem like a lot, but the increased efficiency across the entire system is well worth the hassle of cleaning solar panels once or twice a year.

Q. What should solar panels be cleaned with?

DIYers with experience working on roofs may not need to resort to searching “solar panel cleaning near me” if they have the right tools for the job. Typically, you can clean the panels with a soft brush to remove any larger items, like leaves or sticks. The soft brush won’t damage the panels and it can also clean away dust and dirt.

Use a garden hose to spray the panels and rinse leftover dirt and debris. If there are problem areas, spray the panels with water while scrubbing with the soft brush to remove stuck on dirt and grime without damaging the solar panels.

Q. Does cleaning your solar panels make a difference?

Solar cleaning service isn’t essential for your solar system to work, but it does make a difference in the overall efficiency of the system. On average, dust, dirt, pollen, and other debris can decrease the efficiency of a solar panel by 5 percent or more, depending on the rainfall frequency and the amount of airborne debris in the area where you live. By hiring one of the best solar panel cleaning services to clean the solar panels once or twice a year, you can increase the efficiency of the entire system.

Q. How do professionals clean solar panels?

A professional solar panel cleaner uses a soft brush to remove leaves, sticks, dust, and dirt. They will then rinse the solar panels to remove any lingering debris, but if there are problem areas, they may need to scrub the solar panels with a soft brush and water. The method for solar panel cleaning doesn’t differ from DIYers to professionals, but the job is typically completed much faster, safer, and with better results when you rely on trained individuals that do this work almost every day.

Q. Can I use a pressure washer to clean solar panels?

While a pressure washer may seem like the best way to clean solar panels because it can reach the roof-mounted panels from the ground, the high pressure created by a pressure washer can damage the panels. Never use a high-pressure washer to clean your panels.

Q. How often should I have my solar panels cleaned?

When you are looking for a solar panel cleaning service, it’s important to consider the frequency with which you will need the solar panels cleaned. Generally, it’s recommended to clean solar panels about once every 6 months to a year, depending on the amount of airborne dust and debris in your area.

Q. Should I clean pollen off solar panels?

Pollen will cause the same reduction in overall efficiency as dust, so if you have recurring problems with pollen, it’s suggested to hire one of the best solar panel cleaning services to keep the solar panel system clean and pollen-free.
