Does Solar Panels Need Maintenance (Explained)

Does solar panels need maintenance

Do you want to know how often solar panels need maintenance? Yes, Begin by carefully inspecting their external appearance. If you see cracks, I recommend that you replace the affected panels.

After you’ve finished this check, you may proceed to clean the panels, as I will show later in this post. Solar panels generally require minimal maintenance. 

How often do solar panels need maintenance?

Although they are designed to be durable with warranties of 20 to 25 years. 

However, the need for some essential maintenance is paramount to help their performance and make them stay for a long time.

Let’s get started.

How Often Should Solar Panels Be Cleaned?

The solar panels are ideal to clean once every year. However, a thorough professional inspection every 3-5 years is advisable to ensure a well-performing solar system.

Sometimes, you may want to clean more than once annually because of the environmental condition of the place.

The owner can perform routine cleaning and visual inspections, but you need to contact a professional to do complete maintenance.

It is difficult to establish a precise number of time for cleaning solar panels because it largely depends on several external factors. 

Among these are the amount of pollution in the area where the solar module is positioned and the vicinity of a building site creating substantial dust clouds. 

The existence of solar panels in a forested environment, the presence of panels in an agricultural area, and so forth. 

These characteristics have a significant impact on the frequency of panel maintenance. 

Do Solar Panels Need Annual Maintenance?

Yes, they need yearly maintenance if you choose that way. What I usually recommend is to clean the solar twice a year, which also involves visual inspections.

However, some regions even require you to do maintenance most often. 

Many people also recommend that solar panels should be cleaned before the heat of the season and at the end of the summer, which also makes it twice every year, as I suggested earlier.

That is for an effective all-around solar panel that should be maintained twice yearly, but if your region is not very dusty, you can also do your once-annual cleaning.

What Is The Typical Maintenance Of Solar Panels?

Solar panel maintenance is critical to ensuring maximum performance and lifetime. 

To effectively maintain the solar panel, you must inspect and clean the display of the indicator lights on the box once a year. 

You may also inspect the insulation, the connections’ tightness, the fuses’ and surge arresters’ quality. You can be sure that rats have caused no damage.

Ok, let me go further and show you in sections what you need to focus on for solar panel maintenance.

Regular inspection and maintenance can assist in identifying and addressing faults early on, hence averting possible difficulties. 

Conduct frequent visual checks of the solar panels to detect any damage to the board, such as cracks and loose connections.

Also, inspect the area for any shade concerns caused by surrounding structures.

Schedule a regular cleaning process.

Fix specific times when you want to be cleaning your solar panels. This will help you check that your panels are free from bird droppings, dusty moisture, and other debris that can affect the panel’s efficiency.

Environmental conditions can also affect the frequency of cleaning the panels, as you already know.

Rainfall can be adequate in certain locations to keep panels clean, although more regular washing may be required in desert regions.

Electrical examination

The electrical parts are vital that you also ensue to regularly check on during and after maintenance checks.

The area you should show concern in the electrical check is the wiring that is connecting from the solar to the inverters. 

Even when the cable is affected by rust, it can disrupt the full current supply until you are able to rectify it.

Ensure all the connection points are tight and secure to avoid partial contacts that can cause problems such as hotspots or electrical fires.

Performance evaluation of the solar system

Monitor the performance of the solar panels over time with monitoring equipment.

Analyze performance data to find differences from expected output that may suggest a problem.

Temperature control

Ensure the solar panels are not subjected to severe temperatures since this might reduce their effectiveness.

Consider adding ventilation methods to disperse excess heat and maintain appropriate operating temperatures in hot areas.

Vegetation management 

Trim or remove vegetation that may create shadows on the solar panels, especially during important sunshine hours.

Ensure that trees or plants do not obscure sunlight as they develop over time.

Snow and ice removal process

In places prone to snow or ice, consider measures to remove or avoid buildup on solar panels to retain efficiency.

Inspections of your solar panels by professionals

Schedule experts regularly to examine the overall condition of the solar panel system.

Professionals can detect problems that are not visible during standard visual examinations.

Weatherproofing and sealing

Examine the mounting framework and seals surrounding the panels for gaps and holes.

Check that all weatherproofing measures are in place and the panels are firmly fastened to the mounting framework.

Do Solar Panels Require High Maintenance?

No, solar panels generally do not require high maintenance. Compared to many other kinds of power generating, they are considered low-maintenance. 

However, cleaning, visual inspections, and periodic expert check-ups are often adequate to ensure maximum performance and lifespan.

When natural situations strike, such as hurricanes, hail,  and other physical attacks. All this can break your solar panels and cause them severe damage.

When this happens, in some cases, your insurance policy may have included the solar panels too. 

Otherwise, you will bear the consequences because this type of warranty does not cover it. 

8 Common Solar Panel Maintenance Mistakes to Avoid

Proper maintenance can help to avoid problems that could lead to costly repairs. 

Unfortunately, many people make simple errors in their solar panel maintenance procedures that might harm their investment.

Common errors include:

  • You need to size your home solar system to meet your needs appropriately.
  • Failing to account for vegetation that may block the panels.
  • Hiring a subpar solar contractor.

Continue reading to learn more about frequent mistakes in solar panel maintenance and how to prevent them.

Common Cleaning Mistakes to Avoid

1. Ignoring weather-related dangers

Solar panels can be damaged by weather conditions such as hail or heavy snow. Be proactive in protecting your system during inclement weather.

2. Using abrasive or harsh cleaning agents

Avoid Harsh chemicals and abrasives

The surface of your solar panels is fragile and sensitive to harsh chemicals and abrasive materials. It then means they can damage your solar panels when in contact with such materials.

Because of this, when you are cleaning your solar panels, you should avoid soap or products with harsh chemicals and also avoid the use of aggressive cleaning solutions and abrasive items. 

Any hard action on the solar panels can scrape the protective coating, and that alone can cause the panels to decrease in effectiveness at that moment or cause long-term damage. 

To protect your panels, you must use soft cleaning solutions and non-abrasive brushes.

To remove debris without causing harm, use soft brushes, sponges, or microfiber cloths. 

Avoid using abrasive scrubbers or solvents that may ruin the surface of the panel.

3. Failure to maintain inverters

Just as you clean and maintain your solar panels, you should also plan out also to maintain your inverter. They work together with the solar panel system and should also perform at their optimal level for proper efficiency.

Check that your inverter is clean, well-vented, and working properly. Check the inverter’s display for warning lights or error messages regularly.

4. Failure to do routine cleaning

When you don’t clean your solar for a long time, it will get dirty and can even cause the solar panel to perform less than normal.

5. Improper Cleaning Methods

Cleaning your solar panels incorrectly might scrape or damage the surface. 

Scrubbing too hard or using harsh materials might leave lasting stains or affect the integrity of the product. 

It is critical to handle the panels with care and to use suitable cleaning procedures.

Be careful as you can when cleaning your solar panels, as I have said before it is very fragile and that is why you should gently scrub the surface with a soft brush, and rinse the panels with water to remove the loose debris. 

After that, thoroughly rinse with water. Avoid employing excessive pressure or sharpening 

anything that might scratch the panels.

6. Avoiding Shading Problems

Shading is an important consideration that can significantly lower the efficiency of your solar panel installation. 

Shade problems are commonly caused by overgrown trees, surrounding buildings, or even dirt and garbage collection.

 Trim trees and plants surrounding your panels regularly to keep them clean of impediments.

7. Wrong Wiring or Connections:

To avoid electrical problems, ensure that all wiring and connections are secure and correctly connected.

8. Cleaning Should Be Done During Peak Sunlight Hours

It is dangerous to clean your solar panels during peak sunshine hours. 

The heat the sun produces when extreme can cause cleaning solutions to evaporate fast, leaving residues that may impair the panel’s operation. 

Furthermore, the panels’ heated surface might raise the danger of burns or pain during cleaning.

When Is The Best Time To Clean Solar Panels?

With my experience over the years, with a lot of research I found that the best time to clean your solar panels is in the early morning or later in the evening when the sun is gone down.

This helps the cleaning solution to remain on the surface for as long as necessary for effective cleaning without evaporation, and you can be sure of a proper cleaning than cleaning when the sun is shining, or the weather is still hot.

Final Thought

So far, we have been able to establish how often solar panels need maintenance, which is also the extension of what to avoid when carrying out solar panel maintenance.

The frequency with which solar panels are maintained is critical for improving their performance and existence. 

Neglecting these issues can lead to decreased efficiency, which can cost homeowners money in the long term. 

Solar panel owners may ensure that their investment delivers clean and sustainable energy for years by identifying and correcting frequent maintenance issues. 

That is why, in the long run, expert inspections and a proactive approach to environmental factors serve a protective function.
