Long-term quality of solar panels

The average lifespan of solar panels, also known as photovoltaic (PV) panels, typically ranges from 25 to 30 years or more. However, it's important to note that the actual lifespan of solar panels can vary based on several factors. Most solar panel manufacturers therefore give a minimum 20 or even 25-year warranty on solar panels. An investment in quality and a sustainable future. We tell you more about the lifespan of solar panels.

What determines the lifespan of solar panels?

An increasing number of South African households have already decided to invest in solar panels. Thanks to solar panels, you will be able to save a lot of money, while reducing dependence on the energy grid. On the other hand, a set of solar panels is quite an investment, especially if you choose to buy solar panels. Fortunately, with solar panels, you can be certain to enjoy a long lifespan.


Endurance of solar panels

The lifespan of solar panels is determined by their quality. Quality affects both efficiency and lifespan. To monitor the desired life cycle, solar panels need to meet various quality requirements. At Soly, solar panels are therefore extensively tested both prior to production and after production. As an end user, you are thus assured of the highest quality, reflected in high peak power and strong materials, and a long service life for the solar panels.


Warranty on solar panels

Once the solar panels are installed on top of your roof, they are usually exposed to different kinds of conditions: strong wind, rain, full sun, and even maybe some frost. That is why we are testing our solar modules under the most extreme conditions. We value the highest quality standards, and our warranties on solar panels ensure that you can rely on the same high quality not only today, but also 10 or 20 years from now. A sustainable promise.

Factors that impact the lifespan of solar panels

  1. Quality of the Panels: High-quality solar panels are designed to last longer. Cheaper, lower-quality panels may have a shorter lifespan.
  2. Maintenance: Proper maintenance can extend the life of solar panels. This includes regular cleaning, checking for damage, and ensuring that all components are in working order.
  3. Climate and Environmental Factors: The local climate, exposure to extreme weather conditions, and the environment in which the panels are installed can impact their lifespan. Panels in harsh climates may degrade more quickly.
  4. Manufacturer’s Warranty: Many reputable solar panel manufacturers offer warranties ranging from 20 to 25 years, which often guarantee a certain level of performance over that period. This warranty can provide some assurance about the panels’ longevity.
  5. Degradation Rate: Solar panels experience a gradual decrease in efficiency over time, known as degradation. The rate of degradation is typically very low, with most panels losing about 0.5% to 1% of their efficiency per year. This means that even after 25 to 30 years, panels should still produce a significant amount of electricity.
  6. Technological Advances: Newer solar panel technologies may have longer lifespans or more resilience to environmental factors.

Maintain your solar system to increase its lifespan

While the average lifespan of solar panels is typically stated as 25 to 30 years, many panels can continue to produce electricity well beyond that timeframe. Even after their warranted lifespan, solar panels can still generate electricity, although at a slightly reduced efficiency. Proper care and maintenance can help maximize the lifespan and performance of your solar panel system.
