How Long Do Monocrystalline Solar Panels Last

As a general solar industry rule of thumb solar panels last about 25 30 years.

How long do monocrystalline solar panels last. There are a myriad of factors that impact the vitality of solar panels and the profitability of your system. 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. Yes you read that right. It will cover the nominal power output of the panel during the first year.

Solar panels typically come with a 25 year warranty but in reality they will last beyond 25 years. Over 25 years that adds up to a total of 6 96 meaning your panels will operate at 93 04 of their original capacity in 2045. 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. The general answer for monocrystalline and polycrystalline panels is 25 years.

Chances are if you installed a roof top solar system today it would last longer than your roof. However that warranty typically gets split into two parts. At vivint solar however we work with the best manufacturers and they re so confident in their panels that they offer 25 year warranties. 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.

A panel s degradation rate materials temperature coefficient warranty and caliber of installation all influence how long it ll hold up over time. That being said the federal trade commissionestimates that many solar panels last for about 20 years. When asked how long do solar panels last most installers provide a standard performance warranty of 25 years. For instance if you have installed monocrystalline panels you can continue to use them without any issue for more than 25 years.

Some solar panels are built to last 10 or 15 years while some perform for decades. Of course that number is just an estimate. However solar panels degrade slightly each year and output diminishes by between 0 3 1 0 per year.
