FAQs of FRCABLE'S AL PV Cables
1. How long do Aluminum solar cables last, and are they safe from oxidation?
Modern AL PV cables use high-grade AA-8000 series aluminum alloy, which is highly flexible and resistant to creep (metal fatigue). When jacketed with premium Cross-Linked Polyethylene (XLPE) insulation, these cables offer outstanding resistance to extreme temperatures, UV rays, and moisture. With proper installation and specialized terminations, FRCABLE Aluminum PV wires are designed to last 25 to 30 years, perfectly matching the lifecycle of your solar panels.
2. Are standard solar connectors (like MC4) compatible with AL PV Cables?
No, standard MC4 connectors are generally designed for copper wires. Connecting aluminum wire directly to standard copper terminals can cause galvanic corrosion, leading to high resistance, overheating, and potential fire hazards. You must use specialized AL-compatible connectors (bimetallic terminals) and apply a high-quality anti-oxidant joint compound to ensure a secure, corrosion-free, and long-lasting connection.
3. How do I choose the correct size for an Aluminum PV wire compared to Copper?
As a general rule of thumb, you need to size up the aluminum cable by one or two sizes (in AWG or mm²) to match the ampacity of a copper wire and prevent excessive voltage drop. For example, if your system requires a 10 AWG copper wire, you will typically need an 8 AWG aluminum wire to safely handle the same electrical load. Always consult your local electrical codes (like the NEC) for exact ampacity charts.
4. Can I use Aluminum PV cables instead of Copper for any solar installation?
While Aluminum PV cables are excellent for large commercial and utility-scale projects, they are not always ideal for tight residential rooftops. Because aluminum has lower electrical conductivity than copper, an AL PV cable requires a larger cross-sectional area (thicker gauge) to carry the same amount of current. They are highly recommended for long string runs where space is not restricted.
5. Why are utility-scale solar farms and EPC contractors switching to Aluminum (AL) PV Cables?
For large-scale ground-mounted solar projects, managing CAPEX is critical. Aluminum PV cables offer a significant cost advantage—often costing 30% to 50% less than copper equivalents. Furthermore, aluminum is significantly lighter, which dramatically reduces shipping costs, eases manual handling on-site, and accelerates the overall installation process over long cable runs without sacrificing safety or power delivery.
