How Long Do Pv Solar Panels Last

Most solar panel companies will provide a standard 25 year warranty for the expected life expectancy of the solar panels.

How long do pv solar panels last.

Lifespan of solar panels. The official word from seia solar energy industries association is that the average lifespan of a solar panel is between 20 and 30 years. What happens to a solar panel at the end. However the assurance from manufacturers in the shape of a long term warranty suggests that the lifespan of solar panels is at least two to three decades and likely even longer.

During normal circumstances crystalline panels can withstand extreme heat and cold for more than 20 years. Most equipment warranties last 10 years but some last up to 25. When you re considering investing in a solar installation wondering how long home solar panels last is a question that inevitably pops up. On the contrary film panels usually last for a period not exceeding 5 years.

But current models lose between 6 and 10 efficiency. Average solar panel lifespan. Solar inverters lifespan can vary as most string inverters life expectancy ranges from 10 to 15 years whereas some microinverters and dc optimizers are rated to last 20 to 25 years. Manufacturers determine warranties by how long they feel the product will produce at excellent levels.

To put your mind at ease studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more. As a general solar industry rule of thumb solar panels last about 25 30 years. The average home solar panel system has equipment and performance warranties from the manufacturer. However this doesn t mean that they stop producing electricity after 25 years it just means that energy production has declined by what manufacturers consider to be a significant amount.

How manufacturers calculate the loss of efficiency as stated earlier a crystalline solar panel may last up to 25 years. You can count on most photovoltaic solar panels to last 25 years before they begin to noticeably degrade. When people invest in costly solar panels for their homes or businesses they often hope they will last forever. A simple solar panel life cycle analysis shows that over 96 of pv materials can be recycled.

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. Solar panels also have a separate workmanship warranty to cover any manufacturing defects such as a faulty junction box or frame.
