More and more people use solar panels in their daily life now. They always will buy the high quality solar panels so that they can use them for a long time, but what should they do if they can not not get high quality solar panels? In this post, I would like to introduce about do solar panels need to be replaced?
In genral, if they have got the high quality solar panel, then they can be used for a long time, about twenty to twenty-five years. It is the average lifespan of a solar panel in any weather condition.
Just like other devices, solar panels might need replacement in some cases. But, replacement is the last step of maintenance, and you should replace a solar panel after extreme damage.
As a solar panel consumer, you should know the facts and times about solar panel replacement. It will help keep the panel productive and get sufficient power from the solar system.
With an inefficient solar panel, you can not get expected power from the system, even on a hot summer day.
Solar panels only need replacing when broken, damaged, and can not produce energy. Without these problems and difficulties, you don’t need to replace a solar panel.
Solar panel manufacturers provide a high-quality solar panel with 25 to 30 years of warranty and guarantee.
The warranty period is divided into two sections. The first 10 or 15 years warranty covers the power production that means a warranty of efficiency.
You will get the next 25 to 30 years of warranty coverage, including the panel and body warranty.
If your solar panel can not produce sufficient power and the degradation rate is higher than that of the standard rate, it will be better to replace the solar panel.
On the condition that you think of the end of the life of a solar panel when it will be unable to produce electricity, the lifespan of a solar panel is approximately 20 to 30 years. There is a 5 percent degradation rate per year of any solar panels.
The lifespan are decided by many things, just like the panel’s quality and where you are using it.
Solar panels are made to survive outdoors in any weather condition. So, if you have a high-quality solar panel, it will serve you for your whole life.
As we mentioned above, solar panels’ efficiency remains for 25 to 30 years. It doesn’t mean that you won’t get any energy after this time frame.
The efficiency will be reduced when the panel’s age reaches 40 or 50 years. You can run the solar panel after this high-efficiency period.
You need to replace the 40w solar panel when you are not getting as much energy as you want. You can also add a new solar panel with the existing one to add more power to the old solar panels.
Experts suggest adding a power inverter to enhance the performance of solar panels when the degradation rate is higher than normal.
There is no need to replace the solar panel before 10 years. The manufacturer provides a 25 to 30 years warranty. You will get a replacement or repair from the supplier in this period.
Therefore, you can power your home, office, or devices continuously for a long time. You will have an established and protected power station for years.
However, the situation will be not same in case of an emergency. Such as, if a hurricane or storm damages your solar panel and other destruction, you might immediately change the panel. It depends on the condition, accident, extreme weather, and more. Normally, you don’t need to change solar panels frequently.
The solar panel replacement cost is more than $700 on average. It depends on the damage and size of the panel. The labor cost is $100 per hour. Besides, an entire solar panel removing will cost you $400 – $500, and it is without roof repairing cost.
You have to pay more when removing the solar panel than installing a new one. The job is very technical and needs close attention to do everything.
But you need to remember, you are replacing the solar panel that means it will take removing and installation costs together. If you need to change all the solar panels, the price will be very high.
Anyway, you don't need to replace the solar panels too frequently, and the frequencies is about 25 to 30 years. And the repacing frequencies are decided by many factors. If you take care of them, you can even use them for your whole life. Now you know, there are too many factors you need to consider when you are going to buy solar panels, just like price, features, quality. Among all these factors, quality is the most important one. After all, no one wants to replace the solar panels all the time.
