Long Life Solar Panels

Chances are if you installed a roof top solar system today it would last longer than your roof.

Long life solar panels.

You ll need 2 to bring the voltage up to a useful 12 volts. How long do solar panels really last. Trojan warranties the t 105re for 5 years covering complete replacement for 2 years and a pro rated credit for the remaining 3 years. A study by nrel shows that the majority of panels still produce energy after 25 years albeit at slightly reduced output.

The regular warranty for photovoltaic solar panels lasts 25 years. Here is how the manufacturers come up with this number. They calculate a loss of efficiency of 8 for every year. The warranty typically guarantees panels will work above 80 of their rated efficiency after 25 years.

In reality solar panels can last quite a bit longer than that. Crystalline panels are usually guaranteed for 20 25 years while film panels are generally guaranteed for only 2 5 years. Investing in solar energy is a long term commitment. Studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more.

Key takeaways about the lifetime of solar panels solar panels usually last for 25 to 30 years over their lifetime panels very slowly degrade meaning they may produce less and less electricity high quality equipment makes a difference visit the energysage buyer s guide to compare panels. Luckily the lifespan of solar panels will allow you to produce energy for many years providing a great return on investment.

Yes you read that right.

Especially because your panels will not stop working after 25 years they just won t work as well. The general rule of thumb is that panels will degrade by about 1 each year.
