How long do solar panels last?

If you are considering installing a solar power system in your home or business, one of the questions you might ask yourself is:how long do the solar panels last? And that's a valid question because you wouldn't want to invest in something that will crash after a short time. There are different types of solar panels, but generally they can last between 25 and 30 years. Over the years, solar panels are subject to slow degradation, but certain factors can minimize or preserve their lifespan. If you want to switch to solar energy, you can contact SEM Power. The manager of SEM Power says that installing solar panels is the best way to reduce energy costs for your home and business.

Can you make solar-panels last longer?

Solar panels are usually made with sturdy, quality materials that make them durable. It is common for solar companies to perform tests to determine that their solar panels can easily absorb the impact of wind, rain, snow and other natural hazards. They usually have no moving parts and their maintenance costs are almost zero. The most important tip in buying durable solar panels is to partner with a reputable solar company that offers excellent customer service. It is also important to buy a solar panel that comes with a generous warranty. There is nothing you can do to exceed the rated life of a solar panel, but proper maintenance will significantly slow the degradation process.

Causes of degradation of solar panels

Solar energy is an efficient way to power your home or business. But throughout its lifetime, a solar panel undergoes degradation, which gradually reduces energy production. The average degradation rate is 0.5% per year, and after 25-30 years the energy production has decreased by approximately 12-15%. Various things affect the rate of degradation.

1. Light-induced degradation

The interaction between the crystalline silicon cells of the solar panel and light can lead to degradation. Additionally, improper installation can lead to light-induced degradation, where some vulnerable parts are exposed to harsh light. In addition, exposure to UV rays can cause the silicon particles on the solar panel to react which can reduce its efficiency.

2. Potential induced degradation

This type of degradation has an internal cause and generally reduces the module's ability to generate power. This problem usually occurs when different components of the solar panel have different voltages. This can lead to interruptions which ultimately reduce energy production.

3. Age-induced degradation

Solar panels are usually placed on the roof, and while they are there they are subjected to various conditions which, over time, induce degradation. Climate changes can subject the solar panel to harsh conditions that would cause reactions, corrosion and contamination. All these external and environmental factors have an impact on the solar panel, and they favor its degradation.

Factors-that-control-the-rate-of-degradation

A quality solar panel can maintain its efficiency for up to 30 years, but some things could severely limit its lifespan. Here are some of the factors that control the rate of degradation of solar panels.

1. Material quality

If a solar panel is built with inferior materials, the solar panel ends up being less insulated against various external and environmental factors, which greatly increases its rate of degradation. So, when buying solar panels, you have to consider whether the material is top quality.

2. Panel assembly

The solar panel can be made from high quality material and yet suffer a higher rate of degradation if the assembly of the panel is not smooth. If the components are incompatible, this can lead to disturbances and a subsequent reduction in energy production.

3. Setup

One of the most underrated tips for preserving the life of a solar panel is the installation step. It must be handled properly to avoid small cracks, residues and deposits. The installer must ensure that everything is done correctly. Bad installation tendencies can significantly reduce the life of a solar panel.

4. Maintenance

One of the factors that attract people to solar power systems is their low maintenance costs. But again, solar panels are not a set-and-forget type of system. You should monitor them from time to time to maintain their effectiveness. Solar panels are usually installed on the roof; it is important to examine them regularly, especially after passionate weather conditions such as snow or thunderstorms. Lack of regular maintenance can significantly limit its lifespan.

5. Weather

Changing weather conditions are accompanied by unstable temperatures, thus causing essential components to expand and contract. Solar panels exposed to adverse weather conditions experience a significantly higher rate of degradation. Use protective covers to prevent weather damage.
