As a building decoration material, the service life is undoubtedly a concern for everyone. There are many products in the market that provide quality assurance for their service life, but what is the quality assurance of sunboard? What is the service life of a solar panel? Let's first explore a few questions:
As a building decoration material, the service life is undoubtedly a concern for everyone. There are many products in the market that provide quality assurance for their service life, but what is the quality assurance of sunboard? What is the service life of a solar panel? Let's first explore a few questions:
1. What is the service life of the solar panel related to?
Sunshine board is produced from polycarbonate raw materials, and as a polymer material, the important factor affecting its service life is ultraviolet radiation. The ultraviolet radiation in nature can cause chemical degradation of polymer materials, commonly known as aging. Therefore, solving the problem of ultraviolet radiation is the only way to discuss the length of service life.
2. How to understand aging?
The characterization of aging is that the originally transparent sunlight board becomes dirty, the transmittance decreases, and the color turns yellow during use; The inherent manifestation of aging is a decrease in physical properties, loss of originally high impact and tensile strength, and becoming prone to cracking. The fake and inferior sunboards we often see become very opaque after a period of use, some of which begin to crack and even become brittle, all of which are signs of aging. Delaying aging time, i.e. extending service life.
3. How can solar panels solve the problem of ultraviolet radiation?
The solar panel first uses the extrusion grade high-grade polycarbonate raw materials specially used for the solar panel, which has certain anti-aging performance;
At the same time, while the main equipment extrudes the board, the sun board co extrudes the UV protection layer online, closely integrating with the sun board base layer. This UV protective layer can isolate 99.99% of the UV rays, preventing the board from being attacked by UV rays. Additionally, due to the advanced technology of online co extrusion, the UV protection layer of the solar panel will not delaminate or fall off.
4. What are the Critical to quality points of the UV protective layer of the solar panel?
The thickness of the UV protection layer on a solar panel, which is commonly understood to be many times thinner than hair, how can it be evenly extruded and distributed to a width of 2-1? Firstly, it is ensured through the Italian imported specialized production line for solar panels. Secondly, the quality control department of the solar panels conducts online sampling every few hours and detects 40 points in the width direction. A professional Zeiss microscope is used to test the thickness of the UV protective layer, thereby controlling the stability of the thickness.
If the thickness cannot be uniform, what problems will arise when everyone thinks about it? It is bound to age first in weak areas, and the board looks "flowery".
5. Can the UV protection layer of the solar panel be visible to the naked eye?
Due to the thickness, the UV protection layer of the solar panel is not visible to the naked eye. Some methods in the market, such as observing the color of the fault, are not very scientific. Accurate detection methods require specialized testing equipment, which is equipped in the production factory of Youjing Sunshine Board.
6. What is the meaning of ten year quality assurance for solar panels?
Ten year quality assurance is not a guarantee of lifespan, it is more stringent than a guarantee of lifespan. For example, a television set can usually be used for more than 15 years, but the manufacturer usually provides a three-year warranty, which is not about its lifespan.
The ten-year quality assurance of solar panels is to limit the changes in transmittance and yellowing index within a certain range during the ten-year use process, ensuring that the solar panels have a good state of use.
7. How can Sunshine Board have the confidence to issue a 10-year warranty?
The sunlight board has undergone artificial aging testing (simulating accelerated natural aging), with strict performance testing as the basis;
I believe that with the above knowledge, everyone can have a relatively professional understanding of the service life of solar panels and master some methods in distinguishing the quality of solar panels. Looking at the sunshine boards in the market, there is also a soft evaluation indicator that promises a "qualification" for service life. If we provide a ten-year warranty, which is more reliable, should we have a relatively long production experience? Are there any actual use cases of products that have been around for a long time? These standards can also help you determine how to choose a solar panel.
