Will solar panels last 25 years | Sunerisepv.com

 Can solar panels really last up to 25 years? The answer is yes. Solar panels are not only very reliable, but also their life has increased significantly in the past 20 years.

​

The advantage of solar panels is that they require relatively little maintenance. There is usually no need to clean solar panels regularly, unless your area is particularly prone to dust, dirt, pollen or sand due to drought.

Like most technologies, solar panels naturally produce less energy over time. This reduced power output is called degradation rate. The median degradation rate of solar panels is about 0.5%, which only means that the energy output of solar panels will decline at a rate of 0.5% per year. After 20 years, your panel should still work at about 90% of its original production.

Although solar panels usually require little maintenance, it is still important to check your solar panels from time to time and monitor their performance. Here are some tips to make sure your solar unit is running at full capacity:


Before Installation:
1. Buy solar panels with reliable performance
Solar panels are the most critical part of any solar system installation. Choosing the best panel brand and module type for your situation is the first thing. There are several aspects to evaluate when purchasing solar panels:
1.1 Is the conversion efficiency and power within a reasonable range?
1.2. Is the supplier a manufacturer or a trader?
1.3 Is it a new Grade A solar panel?

2. Work with a trustworthy solar installer
The best way to ensure the longevity of your solar system is to find a reputable solar installer. While solar systems require little to no regular maintenance, some solar suppliers offer comprehensive maintenance packages over the life of their products to ensure they effectively continue to produce clean, affordable and reliable energy for decades.


After Installation:
1. Solar panels should be cleaned regularly
Solar panels require little maintenance. However, it's a good idea to clean your solar panels regularly, as dust and debris can build up on the surface and reduce efficiency. How often you should clean your solar panel depends on many factors, including how often it rains and how dirty it gets over time.

2. Make sure your PV modules are regularly monitored and maintained
Routine maintenance checks will help keep your solar system's panel performance, meters, inverters and other kits operating at peak efficiency. It's also important to note any changes in electricity bills and energy usage.
If your solar panels aren't performing well after rain or being washed by water, or if you notice an unusual spike in your utility bills, it could be an indication of an electrical problem that needs to be resolved by a professional.
