How Long Do Solar Panels Last? Solar Panel Lifespan
Let’s Talk About How Long Do Solar Panels Last? and the Solar Panels Lifespan – The industrial revolution give a rise to a several major serious issues, including energy crises and environmental degradation, which are issues that in Pakistan, like other developing nations, has been suffering since that time. With the discovery of the (PV) photovoltaic effect and the development of the solar panels, it can quickly becames a apparent that the use of the renewable energy was the only way to the end of the highest energy crises and meet the world energy needs and can protect the environment from the carbon dioxide emissions.
Nowadays, solar panel technology is known as one of the greatest renewable energy sources because of its long lifespan, simple installation, and their low cost. The majority of companies expect their solar panels to last for approximately 25 years. It indicates that you are making a very significant investment for a long life runing way.
While there are some great features and components that shorten the solar panels’ lifespan, but you can still use them after the 25-year period time. The main and only difference is will be a noticeably the lower absorbation pof sunlight. we are going to cover the degradation rate of solar panels as well as all the other important information about the lifespan of the solar panels and also about the replacement of the solar panels in this blog.

How Long Do Solar Panels Last
What Is The Degradation Rate Of Solar Panels?
Over the years, some major factors like higher temperatures and an ongoing reduction in the chemical composition of the material will lead the solar panels to lose their ability to absorb the sunlight and convert it into the power. This is a parameter that is known as the (debasement rate) or (degradation rate). It shows that the higher-quality of the solar panel that will degrade at a slower rate, and showing a difference between the both of them. The rate of that the solar plates degrade differs between the panels and between the companies. Don not forget to look into the solar panels rate of degradation and when you purchase your solar system in pakistan.
Based on how quickly they deteriorate, solar panels can be categorized into three groups, which are as follows here down below:
- Tier 1 Solar Panel:
The tier 1 solar Panel Degradation rate is 0.30% and with a 6.96% of Reduction Over 25Years, and the original ouput of solar panel after 25 yuears is 93.04% only.
- Tier 2 Solar Panel:
The tier 2 solar Panel Degradation rate is 0.50% and with a 11.33% of Reduction Over 25Years, and the original ouput of solar panel after 25 yuears is 88.67% only.
- Tier 3 Solar Panel:
The tier 3 solar Panel Degradation rate is 0.80% and with a 17.53% of Reduction Over 25Years, and the original ouput of solar panel after 25 yuears is 82.47% only.
The least reduction rate is found in Tier 1 solar panels, which see only a 6.96% drop in production capacity. After a 25-year period, the tier 2 solar modules are still quite good and have a good production capacity. While the tier 3 solar plates deteriorate by an astounding 0.80%, which significantly lowers their production capacity, but they remain operational the best even after the 25-year period. Since Tier 1 solar panels are highly expensive, we advise to investing in the Tier 2 solar panels, which are more reasonably priced and continues to provide a great performance for up to 25 years. tier 2 solar panels are some of these companies are Canadian Solar and JA Solar.
Are Solar Panels Possible for Early Expiration before the time?
Yes, they can, but only in the case that there is a fault like damage, or manufacturer defected and any other problem with the manufacturer. Apart from that, though, solar panels never get bad because they may continue to provide power even if sunlight absorption weakens yearly. It is true that the solar panels continue to withstand damage and, in some instances, become totally worthless.
Microcracks caused by a frequent severe thunderstorms or hailstorms have the ability to break the solar panels. Although today’s solar panels are sensitive to microcracks, they are not safe to them completely. Unexpected changes in the weather may also be the cause, as they can cause the material which makes up solar panels to quickly reduce and stretch. In the same way, water damage can make solar modules unusable if their seal protection breaks. Many companies provide 25-year promises which often cover these kinds of faults.
Is this is the right time to Replacing Your Solar Panels?
You will need to replace your solar panels if, above the panels planned lifespan, you notice an apparent reduction in the amount of electricity your system produces, insufficient to meet your home’s appliances needs. If, for example, your 20 kWh system is only producing 15 kWh of electricity and there is no failure, debris, or weather punishment, it is likely the time comes for a system replacement because of it has degraded greatly.
This is one of the reasons we advise purchasing a solar system that is larger than what you need in order to maximize the value of your investment during a longer period of time. A monitoring app that displays all the data and may be used to identify and detect the changes in your system’s production is also included when you install a solar system.
Do You Need To Change Any Other Solar System Components?
it is true that the solar panels do not need major maintenance or labor for at least 25 years, the system also includes other pieces of equipment. The biggest part of the system includes a number of PV modules, inverters, and mounting structures in addition to the solar batteries. Compared to the solar modules, these parts can need more regular the maintenance or replacement earlier.
Solar-Powered Batteries
Extra electricity generated by a solar system is stored in the solar batteries. These batteries last on average for around ten years before they begin to deteriorate, so you might need to replace them in order to continue getting the best performance.
Solar Inverters
Because they are the main and important part and can do that convert DC to AC and keep maintain a steady voltage, solar inverters have a comparable 10- to 15-year lifetime to solar batteries. After that, however, they may need to be replaced. Due to their heavy operations, they usually need replacement during the solar system’s lifetime and cannot be expected to continue working after that period.
Mounting Structure
Since the solar panels are drilled into the concrete blocks that have been built on the roof in order to install the solar panels, the mounting structure may also need to be rebuilt. In short, because they are exposed to severe weather because they are on the roof, they could have to be replaced. However, it typically takes it more than 20 years to deteriorate to a stage that’s a replacement is required.
Summary
The solar panels are guaranteed to last for 25 years, but they will can be able continue to generate electricity after that time. The only difference is that the amount of electricity they produce is based on how quickly they degrade. You will have to decide if or not to replace your solar panels. You have to figure out the fact that they are meeting your needs for electricity for this reason or not.
In that case, developing a replacement is basically not required. In the same way, you can continue to use your panels if you have taken care of them and they do not have any microcracks or damaged plates. To guarantee a system’s perfect longevity, always maintain a careful eye on its production and determine if it has to be cleaned on time.
