Different Ways to Make Solar Panels Last Longer


The degrading of solar panels results from many factors that focus on the weather. In particular, microcracks are formed when warm temperatures cause expansion and cold temperatures cause contraction. Unfortunately, solar panels are not immune to this process, and the constant thermal cycling puts strain on them.

Preventative Measures

If you are wondering how long do solar panels last, there are several preventative measures that you should follow. The first step is to prevent animals from nesting in the panels. These animals can gnaw at the wiring and leave debris on the solar cells. This can result in dirty buildup on the panels, reducing their ability to collect sunlight and generate electricity.

Luckily, most solar panels are durable enough to withstand most environmental elements. However, they are still susceptible to cracks or breaks. You can prevent this damage by installing smaller panels or keeping them away from extreme weather conditions. You can also purchase an insurance policy that covers damages due to weather.


When choosing a solar panel, quality is an essential aspect. Ideally, it should produce close to its advertised energy output. Moreover, an excellent solar panel should be more resistant to various elements. For example, high-quality panels should have a low coefficient of thermal expansion, which means they will produce less energy at higher temperatures.

Quality is essential for solar panels because manufacturers produce these products based on standards. This means that it will be easier for consumers to recognize authentic products. Also, a genuine panel should come with test certificates.


One of the most important things you can do for your solar panels is to ensure that they are placed in a location that can receive the maximum amount of sunlight. A solar tracking system can help you determine the optimal angle to place your panels for optimal solar energy production. You can also ensure that your solar panels are cleaned regularly to prevent damage.

To maximize solar output, your solar panels should be facing south. A south-facing panel will receive more sunlight during the late part of the day, while a north-facing panel will receive a smaller amount of light. The optimum orientation will depend on the ratio of peak and off-peak solar energy rates. If you need to generate power at peak times, you should have your solar panels facing slightly west or south.


You can expect an extended warranty to protect your investment when you purchase a solar panel. Many manufacturers offer a warranty of at least 25 years. These warranties will replace or repair damaged solar panels if they are subject to manufacturing defects. Since these panels can cost as much as 70% of your project budget, a good warranty will cover your investment. You can also purchase a warranty covering the entire system, not just the panels.

A warranty will cover a solar panel’s performance and labor. It is essential to check the warranty terms to ensure that you’re getting the most for your money. Some manufacturers only offer a limited manufacturer’s warranty. Other manufacturers offer a performance warranty, which guarantees your solar panels will produce as much as they were rated for.


The increased viability of solar energy has led to concerns about the waste generated from solar panels that are no longer usable. These panels are evaluated for usability and are then repaired or refurbished. Once the process is completed, a certification report is issued.

While the United States does not have the same recycling policy, other countries are moving in this direction. In Europe, solar manufacturers are legally required to recycle solar panels. This process is not cost-effective in the U.S. and is often not feasible for many solar panel manufacturers.
