How Long Do Pv Solar Panels Last

As a general solar industry rule of thumb solar panels last about 25 30 years.

How long do pv solar panels last.

But current models lose between 6 and 10 efficiency. When people invest in costly solar panels for their homes or businesses they often hope they will last forever. However this doesn t mean the panels on your roof will stop producing electricity after a couple of decades. The official word from seia solar energy industries association is that the average lifespan of a solar panel is between 20 and 30 years.

Lifespan of solar panels. When you re considering investing in a solar installation wondering how long home solar panels last is a question that inevitably pops up. To put your mind at ease studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more. 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.

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. 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. A simple solar panel life cycle analysis shows that over 96 of pv materials can be recycled. How manufacturers calculate the loss of efficiency as stated earlier a crystalline solar panel may last up to 25 years.

Average solar panel lifespan. On the contrary film panels usually last for a period not exceeding 5 years. Typically the workmanship warranty is 10 years with some manufacturers offering a 20 year workmanship warranty. Most equipment warranties last 10 years but some last up to 25.

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. The average home solar panel system has equipment and performance warranties from the manufacturer. The standard is 25 years at 80 efficiency.

Manufacturers determine warranties by how long they feel the product will produce at excellent levels. During normal circumstances crystalline panels can withstand extreme heat and cold for more than 20 years.
