How Long Do Solar Panels Last?

Skilled Solar Panel Installers in Vista, CA

Whether you are a home or business owner, purchasing a solar system for your property is no small investment. When you add solar panels to your home, you want them to serve you effectively for years to come. But how long exactly do solar panels last?

While solar panels are designed to last, they won’t stay in perfect condition forever. Like everything else, solar systems are vulnerable to wear and tear. Luckily, if you rely on reputable solar panel installers in Vista, CA, they will maximize the lifespan of your solar system and keep it running perfectly for as long as possible.

Read on to find out more about the expiration date of solar panels.

Do solar panels go bad?Go-to Solar Panel Installers in Vista, CA

The short answer to this question is yes, your solar panels won’t work forever, but it may take as long as several decades for your system to start gradually breaking down.

Most modern solar panels are guaranteed to last anywhere from 20 to 30 years. However, properly installed and maintained solar panels are likely to last quite a bit longer than that, even up to 50 years. What’s more, high-quality panels installed in the 1970s and 1980s may still generate energy, although they may have lost some of their efficiency.

The exact life expectancy of your solar system may also depend on the type of panels you choose for your home or business. For instance, amorphous panels tend to be slightly less long-lasting than their polycrystalline and monocrystalline counterparts. Either way, you won’t have to worry about your solar panels breaking down any time soon if you hire knowledgeable experts for your solar installation and maintenance.

What happens to solar panels after 20 years?

Since solar panels have no moving parts, they don’t typically suddenly break down due to regular wear and tear. On the contrary, solar panels will work efficiently over the course of their lifespan, but may gradually experience slight degradation due to constant exposure to harsh weather and ultraviolet light.

If solar panels do break down suddenly, which is extremely rare, the problem is usually caused by:

  • Faulty solar cell microwires that have caused a short circuit
  • A failure of the water encapsulation system in the panels

Although it is possible for these issues to occur, the vast majority of consumers don’t have to worry about such breakdowns if their solar panels were installed by knowledgeable professionals. In fact, expert installation and high-quality solar panels are the only prerequisites for a long-lasting system.

How much will my solar panels degrade per year?

The exact degradation levels for your solar panels will mainly depend on the brand you choose. According to one study conducted by NREL, the best solar panel manufacturers produce panels with very low degradation rates (0.3% a year), while most brands have the average rates of 0.5%. With a 0.5% degradation rate, your solar panels will run at approximately 88 percent of their initial capacity after 25 years.
