How long do solar panels last?
Solar panels are a popular choice for those looking to reduce their reliance on fossil fuels and save money on energy costs. But how long do solar panels last? The answer may surprise you.
Despite being outside, where they face wind, rain, and debris, solar panels are designed to withstand the elements and continue to produce electricity for decades. Most solar panels come with a 25-year warranty. However, that doesn’t mean that they’ll stop working after 25 years. In fact, many panels will continue to produce electricity for 40 years or more – making them a durable and long-lasting investment.

What’s a solar panel payback period?
The solar panel payback period is the time it takes for a solar panel system to generate enough energy to offset its initial cost. In other words, it’s the point at which the solar panels have “paid for themselves.”
The payback period varies depending on a number of factors. These include the solar panel system size, your local climate, and the amount of sunlight that the panels receive. In general, however, solar panel systems typically have a payback period of between five and ten years.
After the payback period has been reached, the panels will continue to generate free electricity for many years to come. As a result, beyond the payback period, they’re a great way to reduce your outgoings in the future. To put it into context, if your panels last for 30 years, you could enjoy 25 years of free energy!
