How long do solar panels last?

Solar power has rapidly emerged as the preferred choice for those seeking a cleaner, more sustainable energy source. The advantages are clear: solar energy is environmentally friendly, renewable, and can be harnessed right at home, leading to significant cost savings both for the planet and your wallet. It's no surprise that so many households have embraced solar power. However, one common question we receive from customers is straightforward yet crucial—just how long do solar panels last?

One of the key attractions of solar power is its potential for long-term savings. Essentially, the longer your solar panels remain operational, the greater the financial and environmental benefits. Naturally, this raises the question, 'How long do solar panels last?' Having a clear answer helps ensure that your investments in solar energy are accurately calculated and that you can fully appreciate the returns over time.

So, how long do solar panels last?

Research indicates that solar panels typically last between 25 and 30 years. This is excellent news for anyone worried about the durability of their solar system. Even beyond this period, the panels won't simply stop working; they'll continue to generate electricity, albeit at a slightly reduced rate compared to their optimal performance. When we say that solar panels last 25 to 30 years, we're referring to their peak efficiency during this timeframe.

What influences the lifespan of solar panels?

Every solar panel has what’s called a 'degradation rate,' which measures how quickly its efficiency and output diminish over time. Fortunately, modern solar panels, such as those used in Project Solar UK installations, have a minimal degradation rate, hovering around 0.2 to 0.3% annually. This means that even after many years, these panels retain the vast majority of their original capacity, safeguarding your investment for the long haul. If you're asking specifically about the solar panels used by us, the answer is simple—they’re built to last for decades, maintaining more than 95% of their initial output after 25 to 30 years.

Can you extend the life of your solar panels?

If you're pondering the lifespan of solar panels, you might also be wondering if there's anything you can do to prolong their life. In short, the best course of action is to select a reputable solar installer who uses top-tier materials and sets up the system for maximum efficiency. Poorly constructed installations using low-quality components (such as subpar panels or inferior inverters) won't last as long as well-built systems with premium materials. Always check reviews of solar companies and inquire about the specific products they use. Our installations feature SunPower Maxeon solar panels, renowned for their efficiency and longevity. We also incorporate advanced inverters, which convert electricity into usable current, ensuring that no part of the setup detracts from the lifespan of your panels.

Regular monitoring is equally important. Keep an eye on your solar panel performance to ensure it aligns with expectations and to detect any anomalies early. This becomes much simpler if you opt for a solar provider offering app-based monitoring. With a smartphone or computer, you can easily track your solar system's performance and identify any issues promptly. Addressing problems swiftly is essential for maximizing the longevity of your solar panels.

General maintenance is also vital. Ensuring your panels are free from debris and other harmful elements is critical. During installation, we position your panels away from overhanging branches or other hazards. Over time, however, leaves and dirt may accumulate on the roof. Regular cleaning and clearing of debris help maintain optimal performance and extend the useful life of your panels.
