Services life of solar panels

The initial cost of solar panels is usually high, but it pays for itself over time. Aside from the initial cost, there are various tax benefits that come with solar energy.


Although solar panels are durable, they can also wear out quickly. Also, they can endure harsh weather conditions and still provide the right amount of energy for their age.

Although solar panels are among their pluses, their longevity is not as attractive as they seem. In addition, they require various factors to be considered when it comes to their longevity.

If the cells themselves become damaged, other parts of the structure can also get destroyed. This includes the back surface and the protective glass.

The lifetime of solar panels is often an important factor that affects the cost and the energy production system. Generally, it is not possible to predict the lifetime of solar panels before they are installed.


Performance warranty refers to the period of time that solar panels can last. Some manufacturers even promise that their panels will last for 30 years. This does not mean that their efficiency will not decrease.

Most solar panel manufacturers will claim that their panels can produce at least 80% of the rated output during their lifetime or warranty period.

Aside from the technical performance, there is also a comprehensive quality assurance contract that covers the entire life of the product. This type of warranty provides protection against various defects or manufacturing issues that can affect the operation of the solar panels.

There are various types of warranties, such as extended warranty periods and lifetime warranty periods. One example is the 25-year warranty offered by American brand SunPower.

For most manufacturers, this warranty provides a double-sided warranty, which means that they can provide a maximum power percentage of 90-95% for the first 12 years, and a lower capacity of 80-82% for the next 15 years.


A solar panel’s longevity is a vital factor in the cost-effectiveness of its operation. It means that the more electricity it can generate, the more it will pay back.

Solar panels typically have a lifespan of 25 to 30 years.

During their lifetime, the panels slowly but degrade, meaning that they gradually begin to generate less and less electricity.

Different types of solar panels have their own lifespans. As a result, the quality of the solar system components and the individual type of panels are very important to the manufacturer.

Although the photocells and batteries are similar, their characteristics can affect the longevity and payback of the system. For instance, Class A batteries are more durable than Class B ones.

Due to the importance of the lifespan of solar panels, manufacturers are constantly working on improving their indicator. One example is Solarwatt, a leading German manufacturer of solar panels. They now offer a 30-year guarantee on their entire product line.

As the demand for solar power rises, manufacturers are expected to start offering a 30-year warranty on their products. This will bring down the cost of production and make solar panels more attractive to consumers.

Your solar panels are designed to last for a long time, but they should also be aware of the rate of degradation. This is an important aspect of solar energy management.
