How Long Do Solar Pv Panels Last

To put your mind at ease studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more.

How long do solar pv panels last. Solar panels usually last for 25 to 30 years. Most solar panel companies will provide a standard 25 year warranty for the expected life expectancy of the solar panels. 1 however this doesn t mean the panels on your roof will stop producing electricity after a couple of decades. How manufacturers calculate the loss of efficiency as stated earlier a crystalline solar panel may last up to 25 years.

During normal circumstances crystalline panels can withstand extreme heat and cold for more than 20 years. You can count on most photovoltaic solar panels to last 25 years before they begin to noticeably degrade. Assuming the end of a solar panel s life means that it will no longer produce electricity anymore then the lifespan of a solar panel is approximately 200 years 05 degradation per year. However if you re looking for off grid battery based pv inverters you can expect much shorter lifespans ranging from 2 10 years depending on the manufacturer.

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 side by side.
