How long can solar panels last?


The quality and kind of material can affect the lifespan of solar panels, among other variables. Breakdowns caused by wear and tear are extremely uncommon in solar panels since they hardly ever have moving parts. Instead, the rate at which a solar panel’s chemicals deteriorate over time has a significant impact on how long it will last.

Long warranties are typically seen on high-quality solar panels, which shows the manufacturer’s confidence in the product. While the majority of contemporary solar panels come with 25–30 year guarantees, they typically live far longer than this. Materials made of monocrystalline and polycrystalline crystals are especially robust and frequently survive longer than expected. Preventive maintenance, high-quality panels, and expert installation all contribute significantly to a solar panel’s lifespan extension.

WHAT IMPAIRS THE EFFICIENCY OF YOUR SOLAR PANELS?

An abrupt termination of a solar panel’s operation is quite uncommon. Over time, they steadily deteriorate and become less effective. The following four significant environmental conditions could hasten this degradation:

  • Rain. Rainfall that is very heavy might corrode the panel and the structure.
  • Wind. Strong vibrations periodically brought on by high winds may eventually deteriorate the bonding of the solar panel.
  • Heat. Long-term heat exposure eventually makes the panels more fragile, which causes moisture to accumulate, quickly deteriorate, and finally produce less energy.
  • Snow. The accumulation of snow on panels can cause warping, cell cracks, and broken frames.

AFTER 25 YEARS, WHAT WILL HAPPEN TO MY SOLAR PANELS?

After 25 years, the warranty on your solar panel may expire, however this does not necessarily mean the panel will stop working. Although manufacturers often claim degradation rates as low as 0.3% annually, solar panels typically deteriorate at a rate of 0.5% annually.

Due to the low rates, the majority of well-built, well-maintained solar panels will last far into their warranties, even if they operate at slightly lower capacity. In reality, it is not unusual for panels to continue to function for several years after their guarantee has expired. One of the oldest solar enterprises in Southern California reported panels that are still operating 40 years after installation, and the world’s first solar panel is still in operation after 60 years. Even after 30 years from the date of production, one 33W panel still worked better than expected.

HOW TO LONGEVITY IMPROVE YOUR SYSTEM

You can extend the lifespan of your solar panels by adhering to best practices and carrying out routine preventative maintenance. A solar system’s lifespan can be increased in a number of ways.

1. CONFIRM CORRECT INSTALLATION

The first step in ensuring equipment viability over the long term is to use solar panels from manufacturers who have undergone extensive testing and reliability. The functionality and endurance of the entire system can be significantly increased with proper mounting and careful cable management. A top-notch installation will include panels that are firmly connected and wiring that is shielded, removing the possibility of an electrical failure or other physical damage.

2. CHANGE THE INVERTERS

Solar panels have a long lifespan, however inverters need more maintenance and must be replaced after about 10 years. Be aware of the inverters and replace them as soon as they start to fail to prolong the lifespan of the solar system.

3. CARE FOR BATTERIES

Batteries of high quality will normally last 5 to 15 years, however neglect might result in quick failure. A solar system’s batteries should be inspected many times a year, and rechargeable batteries shouldn’t be left unused for extended periods of time.

4. SEEK TO PREVENT LOSS OF EFFICIENCY

The most long-lasting component of a solar power system, the solar panel is likely to outlive its guarantee. However, it’s probable that your system will suffer as a result of the eventual drop in efficiency. The capacity of the system can be increased by adding equipment as needed rather than completely replacing the solar panel.
