When investing in solar panels, it’s important to consider more than just the initial cost and efficiency rating. One key factor that often gets overlooked is the degradation rate.

What is Degradation Rate?

Degradation rate refers to the gradual decrease in power output of a solar panel over time. This is a natural process that occurs due to various factors, including:

• Exposure to sunlight: The sun’s ultraviolet rays can damage the solar cells, causing them to lose efficiency.
• Temperature fluctuations: Extreme temperatures, both hot and cold, can stress the materials in the solar panel, leading to degradation.
• Humidity and moisture: High humidity and moisture levels can lead to corrosion of the solar panel components, impacting performance.

Why is Degradation Rate Important?

While the degradation rate of most solar panels is relatively low, typically around 0.5% per year, it can have a significant impact on your energy production over the long lifespan of the panels.

Here’s why you should consider degradation rate when choosing solar panels:

• Maximize your energy production: Lower degradation rates ensure that your panels continue to produce more energy for a longer period, maximizing your return on investment.
• Reduce your reliance on grid electricity: Lower degradation means you can potentially generate more of your own electricity, reducing dependence on the grid and saving money on your electricity bills.
• Boost your property value: A well-maintained solar system with a low degradation rate can be a valuable asset for your property, making it more attractive to potential buyers.

How to Choose Solar Panels with Low Degradation Rates

• Look for panels with a high initial efficiency rating: Higher efficiency panels tend to have lower degradation rates.
• Choose panels made from high-quality materials: Crystalline silicon panels, for example, typically have lower degradation rates than thin-film panels.
• Compare manufacturer warranties: Many manufacturers offer warranties that guarantee minimum power output over a specific period.
• Research the manufacturer’s reputation: Choose reputable manufacturers known for producing high-quality panels with low degradation rates.

By considering degradation rate when making your decision, you can ensure that your solar panels perform at their best for many years to come and provide you with the maximum return on your investment.

Additional Tips

• Install your panels in a location that receives optimal sunlight: This will help minimize the impact of degradation on your energy production.
• Keep your panels clean and free of debris: This will help ensure they continue to operate efficiently.
• Have your panels inspected regularly: A qualified technician can identify any potential problems and ensure your system is functioning properly.

Investing in solar panels is a great way to save money on your energy bills and help protect the environment. By choosing panels with a low degradation rate, you can maximize your investment and enjoy the benefits of solar power for years to come.
