Having so many environmental problems, because of the waste of natural resources and not taking care of nature, the earth is becoming dried out, and the mankind seeks the ways to find alternative ways, the alternative power energy is already found and is called Solar Energy, gradually Solar photovoltaic industry is getting more and more attention as within time their prices go down and a lot of people considers solar energy as an alternative one for their offices or house power. They find it cheap, clean and reliable. On the background of the increased interest towards the Solar energy, it is expected to increase the demand on solar cables that consists of tinned copper, 1.5mm, 2.5mm, 4.0mm and etc. will be described a bit later. The solar cables are the current transmission mediums of solar energy power generation. They are nature-friendly and much safer than its predecessors. They are interconnecting solar panels.

Solar cables have a lot of benefits besides being nature-friendly they stand out among others with durability that lasts around 30 years regardless of the weather condition, temperatures and they are ozone resistant. Solar cables are protected against ultraviolet rays. It is characterized with low smoke emission, less toxicity, and corrosivity in the fire. Solar cables can withstand flames and fire, they can be easily installed and they are recycled without problems as modern regulations about environment require. Their different colors enable their fast identification.
Solar cables are made of tinned copper, solar cable 4.0mm, solar cable 6.0mm, solar cable 16.0mm, solar cable cross-linked Polyolefin Compound and zero halogen polyolefin compound.All the above should be envisaged to produce nature friendly so called green energy cables. When producing them, they should feature the following: weather resistant, resistant to mineral oils and acids and alkaline. Its maximum conductor temperature of operation should be 120Cͦ for 20 000 hours, minimum should be -40ͦC. As for electrical features, they should possess the following: voltage rating1.5 (1.8) KV DC / 0.6/1.0 (1.2) KV AC, high-6.5 KV DC for 5 minutes.
Solar cables should also be resistant to impact, abrasion and tear, its minimum bending radius should be not more than 4 times of overall diameter. It should be characterized by its safe pulling force--50 N/sqmm.The cable’s insulation must withstand thermal and mechanical loads, and accordingly plastics been cross-linked are increasingly used today, they not only withstand severe weather conditions and are suitable for outdoor usage, but also are salt water resistant, and due to the halogen-free flame resistant cross-linked jacket material they can be used indoors in dry conditions.
Envisaging the above information solar energy and its main source solar cables are very safe, durable, resistant to environmental impacts and very reliable. What is more important they will do no harm to the environment and there is no fear that there will be the power cut off or some other problems, what the majority of the population is facing during power provision problems. No matter what, houses or offices will have a guaranteed current and they will not be interrupted during working, no time is wasted, not much money is spent and no hazardous fumes are emitted during its working causing so much damage to heat and to nature.

1. Avoid “Cable Curves”: Never tie cables in an oval shape. Oval lashings are one of the most common causes of premature failure. This type of lashing can break over time due to movement caused by thermal expansion and wind. Make sure cables run in straight lines rather than ovals.

2. Never tie cables near a metal edge without a suitable product: There is a high risk of damaging the cable sheath, which can cause short circuits and, in the worst-case scenario, a fire.
3. Use appropriate fastening clips for perforations: Use LOC series clips for mounting holes on the solar module. The clip with fir tree and LOC series clips are most suitable for photovoltaic systems. These clips not only secure cables but also enable cable tying—all in one product.
4. Use solar cable clips to avoid drilling panels: Edge clips are some of the most flexible and durable solar cable management solutions on the market. UV-stabilised and made of stainless steel, MSC2 edge clip models allow you to hold one or more cables without drilling. This ensures that cable insulation remains intact and is not exposed to the elements.
5. Take special care with cables in floating photovoltaic systems: For underwater applications or cabling exposed to moisture, ensure that cables and connectors are properly protected and managed to prevent damage.
6. Use mounting points appropriate for the number of solar modules: Cascade effects can result from incorrect sizing of the mounting points. If mounting points are not sized correctly and a fault occurs in one of the fixing elements, a cascade effect may occur, leading to energy loss and potential damage to the system.
7. Clamps for solar applications must meet a wide variety of requirements: It is crucial that clamps are made of materials resistant to UV light and can handle movements, such as those caused by solar trackers. Additionally, clamps in solar applications must withstand various temperature fluctuations.
8. Avoid exposed, sharp, or pointed edges: Sharp or pointed edges can damage cables, potentially causing short circuits.
9. Always ensure proper cable routing: Poor cable management can lead to issues such as excessive strain on junction boxes, resulting in frequent maintenance.
