Are you curious about how long a solar panel will last? Solar panels are a great way to reduce your carbon footprint and save money on your energy bill, but you may be wondering what the life expectancy of a solar panel is. In this blog post, we’ll answer that question and give you some tips on how to extend the life of your solar panels. Let’s get started!
What Causes Degradation of Solar Panels?
Although solar panels come with a warranty, they are not immune to degradation – meaning they can lose some of their initial efficiency over time. So, what are the causes of degradation?
The main reason for solar panel degradation is that the materials they are made from degrade over time when exposed to the elements. Solar panels are also susceptible to physical damage, which can shorten their lifespan.
Solar panels are designed to have a long lifespan – typically 20-25 years or more. But that doesn’t mean they will continue to produce electricity at the same level for the entire duration of their lifespan.
Studies have shown that on average solar panels reduce energy output by 0.5-0.8% each year. So, after 20 years a solar panel will typically still be generating around 80% of the electricity it did when it was first installed.
So, how can you minimize solar panel degradation, you ask? There are a few things you can do to help maximize the lifespan of your solar panels and ensure they continue to generate electricity effectively.
How to Maximize the Lifespan of Your Solar Panels
1.) Keep them clean
Dust, dirt and bird droppings can all reduce the amount of sunlight that solar panels are able to absorb, which will in turn reduce their output. Regular cleaning (at least once a year) will help keep your solar panels running at peak efficiency. Solar Sam offers solar panel cleaning services in Columbia, Missouri, year-round.
2.) Check for damage
Living in the midwest, we are no strangers to storm damage. Tornados, hail, and other severe weather may pose a threat to many homeowners with solar. Solar panels are tough, but they can be damaged by severe weather or physical impact. Inspect your solar panels regularly and look for any cracks, warping or other damage. If you do find any damage, it’s important to get it repaired as soon as possible to avoid further deterioration.
3.) Get a performance warranty
Most solar panel manufacturers offer a performance warranty with their products. This warranty will typically guarantee a certain level of output from your solar panels over a set period of time (usually 10-25 years). If your solar panels don’t meet the promised output, you may be entitled to a replacement or refund. At Solar Sam, we work with you to find the best Solar Panel warranties and options for maximum protection.
While solar panels do have a limited lifespan, with proper care and maintenance they can still provide electricity for many years to come. And, thanks to solar panel performance warranties, you can have peace of mind knowing that your investment is protected.
