In nowadays society that most of people pay more attention on environmental friendly, solar projects become more and more popular as it can produce clean energy without any toxic substances. Photovoltaic cable, which is also called solar cable, plays an extremely important role in solar systems. However, solar systems usually work in outdoor environments where the sun shines for long periods of time, which may be harmful to Solar Cables as they will suffer from UV rays. Therefore, the efficiency of solar system is largely determined by the UV resistance of the solar cable. It’s very dangerous and waste of money if the cables used in solar systems are not UV resistant.
How dose UV Rays Damage Solar Cables?
It's unavoidable for solar cables installed outdoors to be exposed to the sun. As time goes by, UV rays will make solar cables unable to work by damaging the external materials of solar cables, which will also affect the transmission effects of solar systems. There are three main types of ultraviolet light: UVA (less damaging), UVB (more damaging), and UVC (basically doesn't reach the ground).
UV damage to solar cables is first and foremost reflected in the change in appearance. If a solar cable is not UV-resistant, its external material will lose its color and subsequently become brittle and cracked. In case of wire breakage, rain and dust can easily enter the interior of the Pv Cable, affecting its normal operation. More seriously, UV rays may damage the insulation layer of solar cables, leading to leakage, which will not only reduce the power generation efficiency of solar systems, but may also lead to dangerous situations of fire or electric shock. At the same time, the quality of solar cables without UV resistance is a little worse compared to UV-resistant cables, i.e., the service life is not as long as that of UV-resistant cables, which will increase unnecessary cost consumption and adversely affect the relevant projects in terms of economy.
Why Are UV Resistant Solar Cables So Important?
Compared to ordinary solar cables, UV-resistant cables have numerous advantages. First of all, UV-resistant solar cables are less adversely affected by sunlight, have lower wear and tear, and can be used for up to 25 years and beyond, with relatively lower frequency of equipment replacement and maintenance costs. Secondly, UV-resistant solar cables are safer, they can still maintain their original mechanical strength and electrical properties under the premise of long-term exposure to the outdoor environment, so that the overall power generation efficiency of the solar system is higher. In addition, UV resistance is also through the international standard certification (such as IEC 62930, UL 4703, TUV, etc.) of high-quality solar cables is one of the core performance, and has the international certification is equivalent to the product quality of the affirmation, to a certain extent, you can improve the production or use of the solar cable manufacturers enterprises in the market reputation, to attract more consumers to buy and use. Finally, in today's society, where the concept of environmental protection prevails, UV-resistant solar cables are also the right choice to comply with the development of the times, stronger durability means less frequency of replacement and the number of discarded, in addition to fundamentally reduce the generation of waste, part of the UV-resistant solar cable materials can be recycled, to further reduce the impact of the environment, both in terms of economic and environmental benefits have a lot of advantages.
How to Select UV Resistant Solar Cables?
After understanding the effects of UV on solar cables and the advantages of UV resistant solar cables, the topic of how to choose the right UV resistant solar cables is also a topic of discussion. The performance of UV resistance is mainly reflected in the material of the solar cable, for example, XLPE or XLPO these materials are good for UV resistance. In addition to this, the selection should also take into account the actual use of the environment, different geographic environments or national and regional policies will have an impact on the choice of UV-resistant solar cables.
