Solar panels degrade over time and eventually need to be replaced. But how often should they be replaced? This is a question that many people have, and there is no easy answer. Factors that play into this include the type of panel, the environment it’s in, and how well it was installed.

Solar energy is free, renewable, and environmentally friendly. However, solar panels are a significant financial investment, and just like any other piece of technology, they are subject to wear and tear over time. Solar panel degradation is caused by a variety of factors, including UV exposure, extreme temperatures, wind, and rain. As panels age, their output decreases, and eventually they will need to be replaced. The good news is that solar panel technology is constantly improving, and newer panels are more durable and efficient than ever before. With proper maintenance, solar panels can last for decades. And while they may require a significant initial investment, the long-term savings make them well worth the cost.

What is solar panel degradation?

Solar panel degradation is the process by which a solar panel’s performance deteriorates over time. Several factors can contribute to degradation, including environmental conditions, manufacturing defects, and physical damage. Heat and humidity can speed up the breakdown of solar panels, and mistakes in the manufacturing process can cause them to break down early. Physical damage, such as hail or debris, can also reduce a solar panel’s lifespan. Solar panel degradation can have a significant impact on the overall performance of a solar power system. Each year, degradation can reduce a solar panel’s output by a small percentage. Over time, this can add up to a significant loss in power production. Because of this, it is important to keep a close eye on degradation and take steps to stop it.

How long do solar panels generally last?

Solar panels are incredibly durable and can last for decades with little to no maintenance. However, over time, they will gradually degrade and become less effective at producing energy. The average solar panel has a lifespan of 25 to 30 years, but some panels may last longer. The amount of degradation will depend on the type of panel and the conditions it is exposed to. For example, panels that are exposed to high temperatures or are situated in dusty areas will degrade faster than those that are not. Ultimately, the rest of your solar system’s components should easily outlast your solar panels.

How can you slow it down?

Solar panels are constantly exposed to the elements, which can take a toll on their performance over time. There are several ways to prevent or mitigate solar panel degradation.

Keep the elements away from your solar panels

One way to prevent or mitigate this degradation is to reduce your solar panels’ exposure to the elements by installing them in a sheltered location. This could be a garage, shed, or other outbuilding. By keeping your panels out of direct sunlight and protected from wind, rain, and snow, you can help them last longer and perform better. So, if you’re looking to get the most out of your investment, consider installing your solar panels in a sheltered location.

When purchasing, choose long-lasting solar panels

Solar panels are exposed to the elements 24/7, and over time, this can take a toll on their performance. UV rays, wind, and rain can all damage solar panels, making them less effective and eventually needing to be replaced.

Another way to prevent or mitigate solar panel degradation is to choose durable solar panels that are designed for long-term durability. Polycrystalline silicon solar panels are typically more resistant to degradation than monocrystalline silicon solar panels, for example. Solar panels with anti-reflective coatings can also help to reduce degradation by minimizing the amount of light that is absorbed by the panel. Choosing the right solar panels for your needs can help make sure that your investment pays off in the long run.

Monitoring solar panel output/performance overtime

Finally, another way to prevent or mitigate solar panel degradation is to regularly monitor your solar panel’s output and compare it to its expected performance. This will help you catch any early signs of degradation and prepare for it. By taking these steps, you can greatly reduce the risk of solar panel degradation.

Solar panels are an important part of many homes and businesses, providing a clean and renewable source of energy. Solar panels can degrade and become less effective at generating power over time. It is important to regularly check the condition of your solar panels and replace them when necessary. Doing this will help make sure that your home or business can keep using this clean and renewable energy source.
