The lifespan of solar panels and factors to consider when choosing a panel

How long do solar panels last is one of the most frequently asked questions about them. Since solar panels can provide the electricity required by the house, forecasts must be accurate to know the duration and extent of the damage.

The lifespan of solar panels

As a general rule, the lifespan of solar panels is between 25 and 30 years. Of course, this does not mean that there will be no electricity after 25 years; Rather, after this period, the efficiency of electricity generation by solar panels will reach less than the set limit.

Solar panel damage rate; main factor in construction

According to the study, solar panel output drops by 0.8 % every year. This reduction rate implies no function. If they are not damaged by natural disasters like wind or debris, solar panels can last decades.

According to technology development, the reduction rate of solar panels has improved year after year, and some solar-cell producers are expecting the reduction rate to reach 0.5 percent per year.

What does panel demolition rate mean?

A degradation rate of 0.8 means that in the second year your solar panels will have 99% output efficiency and by the end of 25 years of useful life, a panel will have 82.5% efficiency. A durable panel with a degradation rate of 0.5% will produce approximately 87.5%.

How does the solar panel warranty work?

Solar panels can be covered by a variety of warranties. Customers can understand the lifespan of solar panels from these warranties. To ensure how well solar cells generate electricity and function, manufacturers offer warranties and guarantees. These warranties are typically 25 years.

Is it possible to increase the lifespan of solar panels?

Solar panels are generally very durable. Manufacturers test their panels against wind and rain. Due to the lack of moving parts in solar panels, these energy systems do not require any special maintenance.

Solar panels will last for a long time if you choose a company with excellent customer service and a warranty. Panel manufacturers typically guarantee their equipment for 10 to 12 years. The efficiency and production of solar energy is also guaranteed for 25 years.

Solar panels can be maintained continuously to prolong their performance and reduce degradation rates. Here are some steps you can take to extend the life of your solar panel.

  • Ask the service provider to check and monitor your panels regularly.
  • Dust and debris should be kept off solar panels.
  • Solar energy systems can be more stable if the right equipment is used.

The final word

Using solar panels and generating electricity from the sun can help the future of the earth’s energy in addition to investing.
