How long can photovoltaic panels last

How long do solar panels last?

Black monocrystalline solar panels tend to last between 30-40 years, although most don’t come with warranties that exceed 30 years. Meanwhile, blue polycrystalline solar panels will start to struggle slightly sooner - usually at the 25-year or 30-year mark - and these come with a shorter warranty.

How long do monocrystalline solar panels last?

Generally speaking, the degradation rate of monocrystalline solar panels is 0.5% per year. This means that, after 30 years, most monocrystalline solar panels on the residential market will produce 87% of their original power output.

Do solar panels stop working after 25 years?

After 25 years of service, your solar panels will likely experience some decline in efficiency, but they won’t simply stop working. In fact, most panels will continue to produce electricity, albeit at a reduced rate. By this point, the average solar panel will operate at around 80 to 90 percent of its original efficiency.

Do solar panels expire?

There is technically no expiration date on solar panels. However, over time, they naturally tend to become less efficient at producing energy. Some panels can also break due to physical damage from extreme weather conditions.

Are solar panels durable?

Solar panels are generally very durable. Most solar panels are designed and tested to withstand the elements like hail, high winds, and heavy snow loads. And thanks to their lack of moving parts, solar panel systems usually require little to no maintenance. Still, maintaining your solar panels can boost production.

Do solar panels need maintenance?

There are a multitude of solar companies offering maintenance services, which can include comprehensive checks and performance optimization, ensuring your solar panels continue to operate effectively for as long as possible. Understanding the lifespan of solar panels is crucial for anyone interested in solar energy.
