How Long Do Monocrystalline Solar Panels Last

Some solar panels are built to last 10 or 15 years while some perform for decades.

How long do monocrystalline solar panels last.

The general answer for monocrystalline and polycrystalline panels is 25 years. However this doesn t mean that they stop producing electricity after 25 years it just means that energy production has declined by what manufacturers consider to be a significant amount. Yes you read that right. Talking about the overall lifespan of a solar panel it may live up to 25 to 30 years depending on the installation conditions and type of material used for its production.

The 25 year warranty is a limited warranty related to power output. A panel s degradation rate materials temperature coefficient warranty and caliber of installation all influence how long it ll hold up over time. When asked how long do solar panels last most installers provide a standard performance warranty of 25 years. It will cover the nominal power output of the panel during the first year.

For instance if you have installed monocrystalline panels you can continue to use them without any issue for more than 25 years. Especially because your panels will not stop working after 25 years they just won t work as well. Chances are if you installed a roof top solar system today it would last longer than your roof. At vivint solar however we work with the best manufacturers and they re so confident in their panels that they offer 25 year warranties.

However solar panels degrade slightly each year and output diminishes by between 0 3 1 0 per year. Solar panels typically come with a 25 year warranty but in reality they will last beyond 25 years. There are a myriad of factors that impact the vitality of solar panels and the profitability of your system. When determining how long solar panels will last an understanding of the degradation rate and performance ratio will tell you how much electricity they will produce at 25 year mark.

However that warranty typically gets split into two parts. That being said the federal trade commissionestimates that many solar panels last for about 20 years. If you invest in tier 2 solar panels your panels will degrade 50 each year and at the end of a 25 year warranty they will operate at about 88 67 of their original capacity.
