Solar panels can also increase the value of your home. If you ever decide to sell, installing solar panels make your home more attractive to potential buyers and could help you sell for a higher price.

Solar Panel Problems

Now that we've looked at some of the benefits of solar panels let's look at some of the most common problems. 

Delamination and Internal Corrosion

One of the most significant factors in solar panel degradation is delamination. 

Delamination is the process of layers separating from each other. This usually happens when water or moisture gets in between the layers of the solar panel.

When this happens, it can cause internal corrosion, which leads to a decrease in performance and eventually failure.

Delamination and internal corrosion are caused by some factors, including:

Poor Quality Control During Manufacturing

Solar panels are exposed to several chemicals and processes that can cause delamination and internal corrosion during manufacturing. Poor quality control during these processes can lead to problems down the line.

Fortunately for you, we ensure that all the panels we sell are made under strict quality control standards to ensure you only get the best.

Environmental Factors

Solar panels are also subject to environmental factors that can cause delamination and internal corrosion. These include:

• Excessive humidity
• Temperature extremes
• Salt air
• Pollution

All of these factors can cause the layers of the solar panel to separate, leading to a decrease in performance and eventually failure.

Poor Installation

If solar panels are not installed properly, it can lead to delamination and internal corrosion. Poorly installed panels are more likely to be exposed to environmental factors that can cause these problems.

Improper Maintenance

Solar panels require regular cleaning and maintenance to keep them in good condition. If they aren’t properly maintained, it can lead to delamination and internal corrosion.

The best way to prevent delamination and internal corrosion is to have the solar panels installed by a professional. 

Solar panel manufacturers also recommend having the panels serviced regularly to keep them in good condition.

Also, make sure you purchase solar panels from renowned brands. This way, you can be sure that the panels are good quality and will last for a long time. Even though the upfront cost may be higher, it will be worth it in the long run. This is because you will save a significant amount of money on solar panel repair.

Electrical Issues

One of the biggest problems with solar panels is having electrical issues. 

This can be caused by several things, including loose connections, damaged wiring, or even bad batteries. If you're having problems with your solar panels, it's essential to get them checked out by a professional as soon as possible.

Electrical issues can be catastrophic and cause permanent damage to your solar panels. This is why it's important to make sure that everything is properly connected and in good working order before installing your solar panels.

Below are a few tips to help you avoid electrical problems with your solar panels:

Make Sure All Connections Are Tight and Secure

Loose connections can result in solar panels not working. This is why it’s important to check that all electrical connections are tight.

Inspect your Wiring Regularly

It’s also essential to inspect the wiring of your solar panels regularly. Look for any signs of damage or wear and tear. If you see anything, make sure to get it fixed as soon as possible.

Replace batteries regularly

Batteries are one of the most important parts of a solar panel system. They store the energy generated by the solar panels and provide power when there is no sun. Solar batteries should be replaced every few years to ensure that they work correctly.

Micro-cracks

Another common problem with solar panels is micro-cracks. These cracks can occur for various reasons, including extreme temperature changes, physical damage, or manufacturing defects. 

Micro-cracks can cause the solar panel to stop working altogether.

Micro-cracks can be challenging to spot, but there are a few telltale signs that you might have this problem. 

If your solar panel is producing less power than usual, or if you see physical damage to the panel, it's possible that micro-cracks are to blame.

If you think your solar panel might have micro-cracks, the best thing to do is to contact a professional. They will be able to take a closer look and determine if this is the problem. They can help you figure out the best way to fix it.

Solar Panel Shading and Soiling

One of the most common problems with solar panels is shading. This can happen for various reasons, including trees, buildings, and even other solar panels. 

When shading occurs, it blocks the sun from hitting the solar panel directly, which reduces its efficiency. In some cases, shading can reduce a solar panel's output by up to 80%.

One of the biggest problems with flexible solar panels is "soiling." 

This happens when dirt, dust, or bird droppings cover the solar panel and block the sunlight. Soiling can be cleaned off easily with a hose or a power washer in most cases. However, in some cases, the panel may need to be replaced.

Hot spots

Most solar panel failure rates are a result of hot spots. Hot spots are areas on the solar panel that get too hot. This can happen for various reasons, but the most common is soldered connections and dirt accumulation.

Hot spots can cause the solar panel to catch fire or cause the solar panel to stop working altogether.

The best way to prevent hot spots is to keep your solar panels clean and debris-free. You should also check the connections regularly to ensure they are tight and free of corrosion.

PID Effect

PID stands for Potential Induced Degradation, and it's a problem that affects solar panels. When panels are exposed to high temperatures, the electrical potential between the front and back of the panel can become imbalanced.

This causes electrons to flow from the hot side of the panel to the cooler side, which degrades the panel's performance over time.

PID can reduce the power output of a solar panel by as much as 30% over its lifetime, and it's a problem that is particularly prevalent in panels mounted on rooftops.

There are a few ways to mitigate the effects of PID, including using anti-reflective coatings on the glass of the panel and installing panels to minimize their exposure to heat.

But even with these measures, PID is still a problem that most people face. It is wise to seek the help of a professional to ensure that your solar panels are correctly installed and will not succumb to this problem.

Snail Trails

Sometimes, you will ask your electrician to do a solar panel charge controller troubleshooting when your panels stop working. But in reality, there's nothing wrong with your equipment. The reason why your solar panel isn't charging is because of what is known as snail trails.

Snails don’t cause snail trails. They're caused by a thin film of dust and grime that accumulates on the surface of your solar panels. This film blocks sunlight from reaching the photovoltaic cells, preventing them from generating electricity.

They can also be caused by defective silver pastes, manufacturing errors, and damaged anti-reflective coatings.

The good news is that snail trails can be cleaned off. You can use a soft cloth or a brush to remove the film from your solar panel. Be careful not to scratch the surface of the panel.

However, if these trails have overstayed without being cleaned, they can cause permanent damage to your solar panel. This will require you to replace the entire panel.

So, if you see snail trails on your solar panels, be sure to clean them off as soon as possible with professional solar panel cleaners. They have the skills, equipment, and experience to clean your solar panels without damaging them.

Are Materials in Solar Panels Toxic?

One of the most common questions about solar panels is whether their materials are toxic. The short answer is yes. Solar panels may contain toxic materials such as lead and cadmium. 

They also have critical materials such as aluminum, tin, tellurium, and antimony. Some have gallium and indium.

These materials are used because they help create a photovoltaic effect. This is what allows solar panels to convert sunlight into electricity.

However, these materials are also toxic. They can cause respiratory problems, skin irritation, and even cancer. So, if you're planning on installing solar panels in your home, ensure you check the materials used.

It’s best to work with a professional to help you choose the right solar panels for your needs. They also have the necessary skills and equipment to handle toxic materials.

Even though solar panels have several problems, they're still a great renewable energy source. With proper maintenance and care, you can enjoy years of solar power in your home.
