Will Solar Panels Last Long?

Solar energy is the solution if you want to lower your carbon footprint and cut down utility bills at the same time. It is important to invest in a durable solar panel to get the most out of your investment. SunPower is a good brand since it is known for its longevity and lower energy degradation. According to the company, its products will remain usable for over 40 years. Its 25-year warranty is reassuring as well.

Solar Panel Degradation

It is true that solar panels all lose sunlight absorption after some time. This is what those in the industry call degradation. It would be in your best interest to learn more about it to make the right call for your own solar panel. Factors such as hot weather, racking system type, and chemical potency all contribute to how quickly your solar panel degrades. 

Rate of Degradation

According to the National Renewable Energy Laboratory, the median degradation rate of solar panels is 0.5% per year. This can be taken to mean that solar panel production will go down by this much annually. 

By the 20th year, the average solar panel can generate around 90% of what it could in its first year. As a rule of thumb, it is best to look for a solar panel that has a low degradation rate to ensure that it’s able to generate more energy during its lifespan.

How to Improve Longevity

Work with a Reliable Solar Company

Do your research before you choose a company for panel installation. Ideally, they should have extensive experience, great reviews, and good customer service. Always read the contract before you sign anything.

Check the Panels Regularly

Many systems offer a digital monitoring system to keep track of the power output. The panels should produce as much power as promised by the solar company. Make sure to look out for dents, scratches, and other damage since they might reduce the output.

Keep The Panels Clear

Remove any obstruction that might shade the panels. This will include tall buildings, mature trees, leaves, and debris. Such things might prevent the optimum performance of your solar system.
