How Long Do Solar Panels Really Last For?

If you're looking for the life expectancy of solar panels, I'm probably right in assuming you just want a straight answer? To make the sales process quicker, most solar panel installers will give you this, and you can expect to hear something like "solar panels should last up to 25-30 years at optimal power". So would you be happy with this answer? I would recommend you dig a little deeper into warranties to avoid future disappointment.  

Solar Panel Warranty vs output warranty 

As a customer, your first thought is most likely the warranty on the solar panels. Simply, if a solar panel malfunctions during this time, is the panel still under warranty? As Yeames Solar works with multiple manufacturers to create your best home solar solution, these warranties can varey. However, Yeames Solar only works with quality manufacturers that provide warranties of 15 years and over!

So what if you're not familiar with output warranty? Well, every solar panel over its lifetime will encour a rate of degradation (a small percentage per year where energy outputted by the panel is decreased). Now with any quality panel, this should be minimal and nothing to worry about, unless there is a fault with the panel and degradation is lower than expected.

So, do solar panel warranty and output warrenty have the same timespan? Let's compare some manufacturers; where panels are similar in price:

To reflect, If you're just looking for solar panel life expectancy, then you're not going to get the full picture of your solar panel solution, especially when looking for a return on investment as this can come down to warranty. Look for an installer that has options of solar panel manufacturers so that warranties can be compared. Afterall, why settle for less when the price is similar?  

What can you do to make your solar panels last longer?

With sourcing quality and reliable solar panels being just as important as the installation itself, I would recommend you make sure you choose a reliable and trusted installer who designs your solar system with maximum output.

Solar panel maintenance can also make all the difference. It's key to keep any damaging materials away from your panels and keep them clear from debris that could affect performance. Apart from that , just keep an eye on your solar system using provided monitoring platforms:

• Are there any spikes in degradation?
• Is your power generation close to the assumptions made in your estimate?
