There are several key factors to consider when choosing the right type of cable for your solar system.
1. System voltage and current:
For low voltage systems, such as home solar systems, direct current (DC) cable solar is usually the best choice. Standard home solar system voltages typically range from 12V to 48V, so it is critical to select the appropriate size of cable solar. In general, we can choose the cross section area (mm²) of the cable based on the rated voltage and current of the system. For example, for 12V system, the common cable cross section is 4mm²cable solar to 6mm² cable solar; for 48V system, the common cable cross section is 6mm² solar cable to 10mm² solar cable.
2. Weather resistance and high temperature resistance:
Considering that solar cables are used in outdoor environments, you need to choose cables that are weather and temperature resistant. A quality solar cable should be made of special materials that can withstand harsh weather conditions and ensure long-term stable operation. For example, the insulation of solar cables is usually made of polyethylene (PE) or cross-linked polyethylene (XLPE), which has good weathering and high temperature resistance, and is able to withstand external environmental factors such as UV rays, high temperature and humidity.
3. Safety certification and standards compliance:
The safety of solar cables is also an important consideration. You should choose cables that are compliant with international standards and certifications to ensure that their quality and performance meet international standards while minimizing safety risks. Some common international standards include EN50618, UL4703, and others. In addition, some cable manufacturers may also have specific product certifications, such as TUV, CE, etc.
4. Price and supply channels:
Finally, consider the price and supply channels of solar cables. Although high-quality solar cables are usually more expensive, they can provide long-term stable operation of the system. At the same time, choosing a reliable supplier or brand is also a key factor in ensuring the quality of solar cables. You can make the best choice by comparing with multiple suppliers and considering factors such as product quality, price, service and reliability.
By taking these factors into consideration, you can choose the most suitable type of cable for your solar system to ensure efficient operation and long-term stability.
