The Lifespan of Commercial Solar Panels

What is the lifespan of a solar panel?

Solar panels have rapidly established themselves as the UK’s premier popular renewable energy source to generate clean green energy. Today’s most affordable energy resource, solar panels are adopted by businesses to save money on their operating costs – as well as reduce their carbon footprint and promote the environmentally friendly business practice.

Although it is growing in popularity, there are still questions from business owners surrounding the investment potential in commercial solar panels. The most popular concern is how long solar panels last in a commercial setting.

The longer your solar panels generate electricity, the greater the return on your investment is the best answer – and the best way to make your solar panels last the longest amount of time comes down to a few factors.

How Long They Expect to Last

What is the lifespan of a solar panel? Commercial solar typically has a lifespan of 25-30 years, which manufacturers call the optimal rate of operation. Of course, this does not mean that solar panels will cease to work following this timeframe – they can well outperform this lifespan in most cases.

Solar panels typically have the longest warranty of any energy product on the market and are usually drawn up with the degradation of panels in mind. The average warranty on solar panels is around the span of 25 years, which guarantees that the performance level of the panels lasts this period with 90% power output for the first 10 years and 80% over the entire 25 years.

In most cases, solar panels can remain over 80% efficient way past the end of their expected lifespan.

Following 25 Years

When you hear 25-30 years, you have a thought that the panels simply just cease working following this term. That is not the case at all.

Panels continue to produce electricity but at a slower rate in some circumstances due to the degradation. Some solar panels are running upwards of 50 years way past their warranty has expired. It is not a case of it failing.

25-30 years is the expectation of optimum performance levels, not the overall working condition.

What Causes Degradation?

Long term exposure to UV rays and adverse weather conditions are the biggest cause of degradation for commercial solar.

It is extremely cold and areas subject to heavy snow that sees the most effect on solar panels, which is not a regular occurrence throughout the UK – which sees roughly around 2-3 weeks of snowfall a year in most areas.

If you have questions about the installation of commercial solar panels and solar panel cost towards your business, it is recommended to discuss your circumstances and concerns with a professional installer of solar panel systems.
