Solar panels have a limited lifespan. In this article, we’ll discuss how you can extend the life span of your solar panel system and some specific maintenance regimens required for extended periods without degradation or loss in solar panel efficiency with some simple tricks that may keep them going longer than expected!

The Lifespan of Different Solar Panel Types

You might be surprised to know that the life expectancy of your solar panel depends on what type you have installed.

They have a rate of degradation of roughly 0.5% per year, which means you can expect 90% after 20 years if no other factors come into the picture, such as weather and shading. 

Based on this National Renewable Energy Laboratory (NREL) data, it is clear that solar panel manufacturers typically offer warranties of about 25 years or more. And in the case of newer systems, higher-quality panels can last for 30+ years. 

Why do Solar Panels only last 25 years?

The overall flexible solar panel lifespan can be as long as 25-30 years, depending on their installation conditions and the type of material used for electric energy production. The rooftop solar panel lifespan also lasts the same amount of time period. 

For example, crystalline panels are more durable than others. In normal circumstances, monocrystalline panels last longer than 20 years by withstanding extreme heat and cold weather. They’re less prone to damage from moisture or other environmental factors that would cause degradation over time. 

The lifespan of a perovskite panel, i.e., a graphene solar panel lifespan is only 12 months. This short life cycle makes it much less sustainable than traditional solar technologies, which can last up to 25 years. 

On the other hand, film panels are durable for a short period not exceeding five years. Film panels can easily last up to five years before needing repairs or replacements; however, their actual cell lifespan will depend on the type of film panels used. Solar power requires continuous maintenance in order to maintain efficiency. 

Why and how do solar panels degrade? 

When it comes to solar panels, the durability of a product depends on how well they are made. In particular, with crystalline silicon panels – which account for most modern-day variety in power sources– extreme climates can cause them to wear out quickly and leave you feeling powerless as their efficiency plummets too low even before any winter or summer season has passed. 

When solar panels are subject to harsh weather conditions, they can lose their structural integrity and efficiency.

On the other hand, when installed in a favorable climate with minimal amounts of rain or heavy snow, these same components show minimal signs of any degradation over time. 

Let’s take a look at other factors that cause solar panel degradation.

Potential Issues Occurring during the Solar Installation

If you want to really maximize the lifespan of your solar panels, there are a few things that should be considered.

Usually, these aren’t very delicate or prone to defects, but when connecting them with other parts and arranging them into a solar panel array, they need some care because anything could happen at any time, so you need to keep an eye out.

Installing solar panels is a complex process that requires you to consider the safety of your installation and what will happen if the solar installer steps on one.

Despite being durable, these lightweight components can still be disconnected by mistake during placement and connector fitting, resulting in de-energization or other installation issues. 

Tempered glass protects the solar panels from breaking, but it does not protect against stress. This means that there could potentially be micro-fractures in your solar cells over time, which will accelerate the solar panel degradation rate.

Other External Factors Causing Solar Panel Degradation

Soiling is the number one killer of solar cells, and it starts with just a little dirt. Tiny particles start accumulating over time, reducing how much light gets into your panel, decreasing its lifespan dramatically- or until you clean off that pesky grime.

When installed onto flat surfaces such as rooftops, they’re more likely than not going to be dusty and lose their ability due to dirt buildup from construction crews installing it there anyway.

In addition, extreme weather can cause a myriad of problems for solar panels. Suppose the windstorm damages them and breaks from trees in its path or branches fall on top while they’re installed too close together.

In that case, there’s potential degradation because dirt gets into their circuits, leading them to fail over time regardless of whether you use it often enough. 

Birds are the worst when it comes to damaging our solar panels. They love making their nests out of dry areas beneath or just above a panel, which is where they drop different materials that affect panel efficiency by sticking into the panel surface over time – not only does this reduce power production but also increases solar panel maintenance costs for homeowners. 

Major Causes for Solar Panel Degradation or Its Loss of Efficiency

The efficiency of a solar panel to convert light into electricity is measured by how much solar energy output it generates per hour. The more efficient the panel, the better your power bill will be. 

Solar Irradiation

Sunlight is crucial for the operation of a solar panel. Most people think that it’s heat that allows them to produce clean electricity, but in fact, how much power an individual cell produces directly depends on the amount of sunlight falling over its surface area and hitting those solar photovoltaic cells.


A solar panel’s performance levels can be significantly diminished in extreme temperatures. To get the optimal usage out of your investment, make sure to position them away from heat sources such as buildings and pavements that may radiate off excess amounts of electricity into parts of town where it isn’t needed or wanted; also take care when installing, so there aren’t any obstacles blocking airflow. 

Optimal Mounting Position

It is essential to get the best out of your solar panels by installing them in a position that allows for optimum use. Make sure you face it towards the south, at an angle between 15 degrees, and North-South will be most effective with this type of installation. 

Maintenance Failure

To improve efficiency and extend the solar panel lifespan, solar panels require regular maintenance. Without proper cleaning of dust or smudges on these devices, it will significantly lower its performance and increase your electricity bill because you’re wasting solar energy from going through unnecessary inverter conversions.

Key Factors to Make Your Solar Panels Last longer

Solar panels are an efficient and clean form of energy. They require very minimal maintenance, with regular cleaning unnecessary unless your area is highly susceptible to dust or pollen because they live in arid climates with high levels of dirtiness.

When it comes to solar panels, maintenance is vital for a successful installation. Here are some tips on how you can keep your system running smoothly and efficiently:

#1 Keep Your Panels Debris-free & Other Damaging Materials

Your solar panels are designed to work in harmony with the environment around them, but an accumulation of dirt and bird droppings can affect their efficiency.

If you notice this happens regularly on your own or if it becomes apparent after the rain has fallen – consider hiring a professional cleaning service for assistance.

Make sure you don’t put your solar panels under branches because it could reduce the amount of sunlight they receive and cause them to fail. Branches falling during storms can be hazardous and cause severe damages. 

If you have Panel Damage or Obstruction due to any of the following elements, contact your solar provider immediately.

They will be able to assist in taking further action for physical damage control and provide training on how best to use their equipment and panels properly. 

#2 Ensure a Regular Maintenance and Monitoring Done to Your Panels

Routine maintenance checks ensure that your solar system’s panel performance, meters, and other parts stay in peak condition.

It would be best to note any changes in bill and energy usage when performing this procedure to ensure that everything is at its peak efficiency.

Your solar panels might not be performing optimally after rainfall or being hosed down with water. If you notice that your electricity bill is unusually high, it could point to an electrical problem. A professional electrician will know what needs fixing.

#3 Track Down a Trustworthy Solar Provider

Your solar system will be the best investment you could ever make if it has a reputable company that offers comprehensive maintenance packages.

The least expensive and most important way to ensure your longevity in this industry would be by hiring professionals who can provide affordable energy for decades without hassle or worry about what happens after installation day.

Concluding Note
