For many house and business owners, solar panels are an excellent investment. According to research, 66.5% of those who do not have house solar panels are interested in having them in the future. However, if you want them to work well, you should perform routine maintenance and clean solar panels effectively.

If you want to get the most out of your investment, learn how to clean solar panels properly. It is beneficial to both your money and the environment. Here’s our step-by-step guide to cleaning solar panels, including instructions for cleaning solar panels on a roof.

Importance of Cleaning Solar Panels

To clean solar panels on a regular basis is an important element of solar panel maintenance. Although it can be time-consuming, keeping your solar panels clean has numerous long-term benefits.

Cleaning solar panels on a regular basis prevents dirt and debris from accumulating and ensures they remain in excellent working condition. Furthermore, trash heaps may cause scratches that could permanently harm your panels.

Cleaning your panels on a regular basis also lowers the possibility of having to replace them. Overall, keeping your solar panels clean allows them to produce more energy, which saves you money by offsetting your energy cost.

When Should Solar Panels Be Cleaned?

Knowing when and how frequently to clean solar panels is critical.

The timing varies depending on the system you own, its location, and the amount of maintenance required by service specialists. Other key things to consider when determining how frequently to clean solar panels are:

  • Climate conditions
  • Environmental factor
  • As well as the season

Rain, for example, aids in the removal of dirt and debris. As a result, if you live in a dry climate, the lack of rain will necessitate extra hand washing of your panels.

Cleaning your solar panels, on the other hand, does not have to be done as frequently as you may imagine. Expect to clean your panels once or twice a year on average.

If you want to get your solar panels professionally cleaned, you need to find out how much professional solar panel cleaning costs.

Some solar providers charge a set fee for cleaning services, whereas the majority charge per panel.

However, your final payout is determined by a number of circumstances. Some examples are:

  • The number of solar panels that must be cleaned?
  • Panel dimensions (commercial panels are larger than residential panels)
  • The amount of dirt and debris accumulated
  • The type of surface on which the solar panels are installed (ground, wall, or roof)
  • Your roof’s type and slant

To get a better idea of how much expert cleaning may cost you, get a quote from your solar provider.

Materials Required To Clean Solar Panels

When learning how to clean solar panels, you should also consider what cleaning materials you will require. Using the proper equipment and products will allow you to wash them more completely and keep them cleaner for longer!

First, gather some water (a regular water hose or buckets of water are fine). After that, gather a soft cloth or sponge, a soft brush or leaf blower, and a squeegee.

It’s a good idea to utilize basic safety equipment when cleaning solar panels on a roof. A strong ladder, safety glasses, and a helmet are all recommended. If possible, utilize a safety harness.

But there are a couple of things to keep in mind. Hiring a solar specialist that specializes in cleaning is usually a good idea.

Going atop your roof might be dangerous, especially if it’s high and sloping because an accident could occur.

Furthermore, frigid locations with temperatures below freezing may cause the water you hose onto your panels to freeze. To lessen the probability of ice developing on your panels, use very warm water or wait until the temperature rises.

Of course, a fall safety system should always be used.

Safety Measures TO Consider When Planning To Clean Solar Panels

The Occupational Safety and Health Administration (OSHA) has several fall protection regulations. These regulations apply to service personnel that installs or maintain solar panels, including cleaning them. They are, nevertheless, equally important for non-service professions to consider.

OSHA mandates a conventional guardrail if the fall danger is 4 feet or higher. Alternatively, if your solar panels are at least 6 feet above the ground, OSHA mandates the following fall safety methods:

  • System of guardrails
  • System of safety nets
  • Personal fall protection systems

On their website, you can learn more about OSHA’s recommended safety precautions and enforced rules.

how-to-clean-of-solar-panels-effectively

Learning how to clean a solar panel properly is critical if you want your system to perform optimally. Furthermore, regular cleaning prevents unwanted damage to your panels and preserves them in good shape for years.

The most crucial measures to take when cleaning your panels are outlined below.

1. Verify The Manufacturer’s Instructions

Begin by reviewing the manufacturer’s instructions. They detail the steps on how to clean your specific solar panel brand. Following those guidelines can also help you avoid causing unneeded harm to the panels.

2. Get Rid Of Loose Dirt And Debris

Also, before cleaning your solar panel system, make sure you turn it off. The manufacturer’s instructions should explain how to turn your system off.

After that, clean up any loose dirt and debris from the panels. Dirt and debris can quickly build and reduce the efficiency with which your panels generate energy. Before cleaning the panels, use a leaf blower to remove the majority of the accumulation.

Furthermore, whenever and if you get on top of your roof, make sure to protect yourself. Wearing appropriate work attire, non-slip footwear, and, most importantly, employing a fall protection system are all part of this.

This is a simple and necessary precautionary measure to avert major mishaps.

3. Spray Water

Next, spray the panels with water to eliminate any remaining dirt, dust, or debris.

However, high-pressure water sprayers or water jets should not be used for this stage. The intense water spray has the potential to harm the panels.

The power of a high-pressure water sprayer might potentially cause you to lose your balance. Make use of a low-pressure hose or buckets of water.

When learning how to clean roof solar panels, climbing on the roof may allow you to clean them more thoroughly. However, be cautious because water might make the roof slippery. When cleaning roof panels, wear protective equipment.

4. Squeegee

Use a squeegee to remove any surplus water after cleaning the panels with water. Because it avoids mineral buildup, this procedure is especially crucial if you have hard water.

Use a squeegee with an extension handle if you have one. This allows you to remove water from difficult-to-reach regions.

5. Avoid The Use Of Abrasive Products

Finally, avoid using abrasive materials. Harsh detergents or rough sponges can harm your panels and reduce their effectiveness. Some detergents can also destroy your panels.

To maintain solar panels effectively, clean them using just water, gentle sponges, and soft cloths.

What is sustainable development?

According to the United Nations, sustainability means “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

Solar energy embodies this widely accepted definition of sustainability because the sun’s energy can be used indefinitely without diminishing its future availability.

In addition, most experts agree that the sun is the most important source of renewable energy.

Solar energy doesn’t just help reduce your electricity, it helps save humanity.

What are sustainable development goals?

The Sustainable Development Goals (SDGs), also known as the Global Goals, were adopted by the United Nations in 2015 as a universal call to action to end poverty, protect the planet, and ensure that by 2030 all people enjoy peace and prosperity.

Use of solar energy provides environmental, social and economic benefits that can accelerate the world’s trajectory towards SDGs. Solar energy contributes to the reduction of poverty, and access to affordable and reliable electricity.

Solar energy and sustainable development

What is the impact of solar energy on the environment?

The sun provides a tremendous resource for generating clean and sustainable electricity without toxic pollution or global warming emissions. The sun is finite. Hence, the use of the sun in generating electricity has the following advantages:

Conserves water

A lot of traditional electricity production requires the use of water. This can consume thousands of litres of water per year.

Water is used for cooling generators, processing and refining fuel and transporting fuel through pipes.

However, generation of power through solar panels does not require the use of water.

Solar panels come in different types. Each type with its unique set of advantages and maybe, disadvantages.

It is important to know the different types of solar panels because your choice will determine cost and amount of roof space your solar installation requires.


What is a solar panel?


Solar panels are used to collect solar energy from the sun and convert it into electricity.


A solar panel is composed of individual solar cells. Each solar cell is made from layers of silicon, boron and phosphorus.

The boron layer provides the positive charge, the phosphorus layer provides the negative charge, and the silicon wafer acts as the semiconductor.


When the sun’s photons strike the surface of the panel, it knocks out electrons from the silicon “sandwich” and into the electric field generated by the solar cells. This results in a directional current, which is then harnessed into usable power.


The entire process is called the photovoltaic effect, which is why solar panels are also known as photovoltaic panels or PV panels. A typical solar panel contains 60, 72 or 90 individual solar cells.


Types of solar panel


There are three main types of solar panels that are commercially available. They include:

• monocrystalline solar panels
• polycrystalline solar panels
• thin-film solar panels


Monocrystalline solar panels


Monocrystalline solar panels are the most popular solar panels used in rooftop solar panel installations today.


Monocrystalline solar panels have unique features considered better than the other two types of panels. They are as follows:


•The pyramid pattern of the cells offers a larger surface area to collect more energy from the sun’s rays.


• The cells are coated with silicon nitride to reduce reflection and thereby increase absorption.


• The produced electricity is collected through metal conductors printed onto the cells.


• It has higher efficiency of conversion of solar energy into electric energy than its two other counterparts.


• These panels have longevity up to 30 years.


• These panels exhibit greater heat resistance.


Applications


Because of their many advantages, monocrystalline solar panels can be used as follows:


• Can be used as solar rooftops in urban and rural areas.


• These panels are highly recommended for solar applications on a larger scale – on vast tracts of uncultivable land.


• These panels are also useful for residential and commercial applications.


• These panels are extremely useful in lighting up gardens.

• These panels can form an array and used to power rural homes.


• These panels are perfect for street lighting as stand-alone panels.


Polycrystalline solar panels


Polycrystalline solar panels are solar panels that consist of several crystals of silicon in a single PV cell.


Features of polycrystalline solar panels include:


• Polycrystalline solar panels have lower heat tolerance than monocrystalline panels. So, at higher temperatures, these solar panels have lower efficiency than others.


• Polycrystalline solar panels have a higher temperature coefficient than monocrystalline panels.


• These panels have a high power density.


• They come with a structural frame of their own which makes mounting cheaper and simpler.


Application of polycrystalline solar panels:


• They can be used in large solar farms.


• They are suitable for roof mounted arrays.


• They are used in self-powered devices such as traffic lights, and off-grid households.


Thin film solar panels


A thin-film solar panel is made up of one or more thin layers of photovoltaic materials that are laid onto a substrate.


Features of thin film solar panel:


• They are more flexible and light weight


• Installation is much easier than the others


• These solar panels are most suitable for applications with large rooftops or wide open spaces.


Application of thin film solar panels


• They can be used in solar farms


• They can be used to power traffic lights and street lights.


• They can be installed in large-sized steel water tanks to provide electricity for pumping water.


Conclusion


Solar panels come in three main different types: monocrystalline, polycrystalline and thin film solar panel.

Knowing the difference between each of them helps you in making the right choice during solar panel installations.

Is it possible for your solar panel to lose efficiency? It is very possible! You didn’t know? Now you do. There are certain factors that affect solar panels, and this results to a decline in efficiency.


Knowing these factors will help you do better with maintenance.

In this article, we’ll be looking at things that could affect your solar efficiency.


Keep reading to find out more.


What is a solar cell?


A solar cell or photovoltaic cell is a device that converts the sunlight into usable energy. The amount of sunlight that can be converted into electricity is referred to as solar cell efficiency.


What are the things that could affect your solar panel efficiency?


There are some factors that should be taken into consideration to guarantee the optimal efficiency of the solar panels.


The factors include:


• Sun


• Installation issues


• Weather


• Mounting position


• Poor maintenance


Sun


As we know, the solar panels work with the amount of sunlight and not heat from the sun.

The greater the amount of light incident on the panels, the higher the efficiency of the solar panels.


Installation Issues


Unfortunately, there are problems that are caused from the very start, caused by a less-than-stellar installation job.


It’s important to remember that solar panel installation is not a simple or easy job.

It’s not just a matter of installing panels onto the roof — because the solar system is a source of energy for the entire home, it has to connect with the electrical grid, and a careless installer might not implement these connections as well as they require.


Also, the condition of the roof is also a major factor.


Weather


Solar panels are designed to stand on top of your home all day, every single day, for decades.

For this reason, they’re engineered to hold up well against the elements, but that’s not to say they’re completely immune.


Sadly, the weather can indeed have an effect on your solar panels, and in extreme conditions, can even damage them.


Mounting position


Even if your solar panels are perfectly installed with zero issues in the connections or structural integrity, they might not work at optimal efficiency if they’re not oriented well.


We all know that solar panels absorb sunlight, so they should be positioned in such a way that they get as much exposure as possible at all times of the day.


Poor maintenance


Maintenance is key in prolonging the life span of a thing.
In a case where you don’t carry out periodic clean up on your solar panels, the presence of dust and dirt on the solar panels will drastically reduce their efficiency. Regular cleaning is recommended for all solar panels.


Conclusion


Solar panels can lose its efficiency. Some of the factors that can cause this includes: Poor maintenance, mounting position, weather, installation issues and the sun.

Solar panel systems can last for years even with limited maintenance checkups. However, a little knowledge on solar power maintenance can go a long way because regular checkups will save you costly repairs down the road, and keep your panels looking nice and shiny.

Solar panels are exceptionally easy to care for. They’re made out of tempered glass, which holds up well in tough conditions, and there aren’t any moving parts. It’s also not a bad idea to be well versed with each solar component in order to maintain your solar panel system.

Thinking about ways to maintain your solar panels?

We have listed three easy steps to on how to care for your solar panels below. Let’s go!

How To Maintain Your Solar Panels In 3 Easy Steps

1. Clean regularly

In places that experience regular rainy seasons, solar panels do not need to be cleaned too often. The occasional rain will take care of any dust, or snow (if experienced) will melt faster on the panels than it will on the rest of the roof.  

However, it’s a good idea every few months to glance at the panels and make sure there is no residual dirt, dust or leaves. If there is, a light rinsing off with a hose should take care of the problem.

It is not advisable to get on the roof to clean the panels. If there is a serious dirt buildup, consider investing in a long-handled broom or hose. If there’s a buildup of leaves, consider using a roof rake to take care of this problem.

2. Do a regular checkup with a solar monitoring device

Solar monitoring makes certain that your solar panels are working properly by tracking the power output of your system. With solar monitoring, you gain 24/7 peace of mind that your panels are working as efficiently as possible.

This helps you know when to carry out cleaning and general maintenance of the panel to increase efficiency.

3. Employ the services of a professional

Cleaning solar panels is an uncomplicated procedure that you can take care of just as well as a professional. If you have a small installation, it pays off to clean it on your own because the cost of professional cleaning would exceed the estimated energy gain associated with clean solar panels.

Also, you can also ask your solar installer to clean your panels while he is performing routine technical maintenance. He can execute this task in complete security.

Conclusion

Solar panels generally require very little maintenance in order to function. The only thing they need is a periodic light cleaning, routine checkups or employing a professional to do the work.
