NNC Top Solar Wires and Cables
The solar energy market is one of the most rapidly growing energy markets in the world. In 2021, the international market for solar energy systems was valued at 160.3 billion USD. From 2022 to 2030, it's projected to experience a compound annual growth rate (CAGR) of 15.7%. Therefore, it is natural that an abundance of cable products for solar panels are available on the market. This quick guide will help you understand the differences between the main types of solar cables offered by NNC.
Photovoltaic cables come with aluminum and solar conductors. Both are popular, with aluminum being much cheaper than copper. Copper photovoltaic wires have superior electric conductivity. If you want to investigate the difference between the two in more detail, study this blog.
Aluminum Solar Cables
Aluminum 600V Photovoltaic Cable Utility Wire is a standard aluminum PV cable for low-voltage solar power systems. It is used in grounded and ungrounded solar power systems. The cable is equally suitable for commercial and residential wiring. The aluminum used in this type of cable is the compressed 8000 series aluminum alloy. It has a better conductivity compared to other kinds of aluminum available on the market.
Aluminum 2KV Photovoltaic Cable Utility Wire is an aluminum PV cable used in high-voltage applications. High-voltage solar panels are generally more powerful. They produce more consistent power and generate electricity much faster. Low voltage panels also have their benefits. Their installation costs are cheaper, they are easier to install, and the probability of electrical shock is much lower.
Copper Solar Cables
PV Wire Photovoltaic Cable Single Core 2000V This photovoltaic cable with a copper conductor is suitable for direct burial. It carries RHH/RHW-2 and RWU90 ratings. The voltage of the cable is 2000v.
PV Wire Photovoltaic Cable Single Core 600V is an analog of the cable described above. Unlike a 2000V cable, it can also be used for USE-2 applications. Both 600 V and 2000V photovoltaic cables of this type are single-core, which means that they have a single conductor and insulating layer.
PV Wire Photovoltaic Cable 2000V mm² is a multi-strand copper photovoltaic cable. Having multiple conductor strands is often beneficial for photovoltaic cables because if there is damage to a set of strands, the others will keep on working.
USE-2 Cables and Other Solar Cables
Aside from photovoltaic cables, USE-2 cables and other copper and aluminum cables can be used in photovoltaic panels. USE-2 is a cheaper alternative that can be used in grounded low-voltage 600V systems with a temperature rating of 90°C. Both aluminum and copper USE-2 cables are suitable for solar panels.
Aluminum TRXLP 25KV 100% Cable: This cable, constructed with XLP insulation, serves as a concentric neutral distribution cable designed for medium-voltage uses in solar farms. It's suitable for establishing connections among various sections of a farm, distributing power, and facilitating underground setups.
XLP USE-2 RHH RHW-2 Copper Building Wire: This is a durable and adaptable power cable equipped with a copper conductor and XLPE insulation. It's ideal for establishing connections between photovoltaic (PV) solar panels and suitable for direct burial uses.
UNSHIELDED VNTC TRAY CABLE W/ GROUND TC-ER THHN INSULATION PVC JACKET 600V: Copper tray cable with PVC insulation, utilized for off-grid solar tasks, such as wiring solar panels and charge controllers.
