Nitty Gritty About Solar Panel Degradation

The solar panel degradation rate

Solar energy is a blessing for the earth and one of the most abundant sources of renewable energy. The solar system had been in use commercially as well as domestically. Solar panels are responsible for the conversion of sunlight into electrical energy but, are you aware of the fact that they too have a limited timeline for working eminently? Their potential too got lessened over time. So, in this article, you will be recognizing solar panel degradation and degradation rate.  

About solar panel degradation & degradation rate

In simple words, the fruitful life of solar panels i.e. the electricity yield from the panels reduces over time due to the factors like weather, solar panel racking, and the type of module used. This reduction in electricity production is called solar panel degradation. These factors impact heavily on the panels and as a result, the output of the panels gets reduced over time. 

This degradation in the electricity output of the panel happens at a rate. This rate at which electricity production gets reduced is called the solar power degradation rate. In the current marketplace, the average rate at which the available solar panels degrade is 0.5% per year. This implies that there is a 0.5% decrease in electricity production every year. Depending on this rate, the expected life span of a solar panel is about 20-25 years. 

Why comprehend solar panel degradation rate?

Pondering over the degradation rate of a solar panel is coming out to be one of the crucial factors before investing in it. Keeping a check on the degradation rate helps to select an appropriate solar panel for your roof. With the understanding of the degradation rate, one can opt-out of a cost-saving module for a longer life span. 

The solar panel needs maintenance slowly but surely, so by having a ken of degradation rate, one can take advisable steps for placement, inspections, cleaning, and maintenance. Also, one can take effective measures to keep the solar panel degradation rate as low as possible. 

Factors affecting the degradation rate

There are various causes for the downfall in electricity production. Some of these are material type, solar panel mounting & assembly, climatic conditions, and preservation. The degradation rate differs from area to area and person to person. Transition in the degradation rate can be observed from the manufacturer to the installer and the purchaser.

Possible elements contributing to the degradation are:

Material Type

The metal used for making the frames of the solar panel must be of good quality otherwise, cracks can be spotted on them. The solar glasses and the solar cells also must be made up of standard quality metal for no compromise with the performance of the panel. 

Mounting & assembly

It is recommended to take special care while mounting the panels. The scratches and wrong wiring can cause serious harm to them. There should be legitimate handling and installation while assembling the system. 

Climatic conditions

Year by year, climate change and contrasting weather conditions affect the degradation and impact electricity production steadily. Therefore, precautions could be taken for preservation.

Final Words

Solar panel degrade over time and exhibits a decline in production. The degradation rate helps in determining the reliability and efficiency of the solar system. When it comes down to making a choice, homeowners & businesses must carefully consider the degradation rate for better performance.
