Today, there are over 2 million solar installations in the US. In fact, it’s predicted that by 2024, 2.5% of all American homes will have one!
All this hype over green energy might have you curious about getting home solar panels. But how long do solar panels last and is it worth your money? Read on to find out!
How Long Do Solar Panels Last?
On average, solar panels should last you about 20 years. Do note that this doesn’t mean they’ll just break down completely after 2 decades. Instead, it just means they won’t be as efficient as they were in the beginning.
But 20 years is just a rough estimate. Here are some factors that’ll influence how long it’ll take before you need new solar panels.
All solar panels should take wind just fine to a certain degree. But if you live somewhere that gets high winds and/or lots of bad storms, this will drastically reduce your solar panels’ lifespan.
This is because the panels can get shaken and debris might fall on them. This will break down the bonding on your solar panels and also cause them to get scratched up.
There’s a misconception that solar panels should be able to withstand heat. But in reality, their main purpose is to absorb UV rays, not actual sunlight itself.
What this means is if you live somewhere that gets hot weather, this can cause your panels to become brittle. As a result, they might crack and break, as well as become discolored.
Heat might also allow moisture into your panels, which can damage them.
Snow isn’t as bad as the above, so long as you’re proactive.
When snow falls on your solar panels, they can weigh them down. Not to mention, they can also cause the cells to freeze over. Both can cause your panels to crack and break, as well as warp.
As soon as the snow falls, clear off the panels when you can. This will ensure there’s no buildup and will prolong your solar panels’ lifespan.
Not only can external factors affect the lifespan of your solar panels, but so can the initial installation. If it’s a mediocre or badly done job, the above will only accelerate your panels’ deterioration.
To ensure this doesn’t happen, you should only work with reputable companies, such as Blue Raven Solar.
Enjoy the Benefits of Solar Panels
Now you know the answer to the question, “how long do solar panels last?” While they’ll last about 20 years, do keep in mind that your local environment will affect the lifespan of your particular solar panels.
In any case, have peace of mind knowing that they won’t completely break down at the end of the 2 decades of installation. So even though there’s a high initial cost, it’s definitely worth getting some solar panels installed for your home!
