This 6 mm² TUV approved solar PV cable features a tinned copper Class 5 conductor with a cross-linked polyolefin (XLPO) primary insulation and XLPO outer jacket — combining the highest UV resistance XLPO compound with tinned copper corrosion protection to deliver a 25+ year outdoor service life in even the harshest solar installation environments. TUV Rheinland approval confirms independent testing compliance with EN 50618 and the H1Z2Z2-K performance designation.
The 6 mm² cross-section is optimised for utility-scale and large commercial string wiring where higher string currents (typically 15–20A with modern high-efficiency bifacial modules) and longer string cable runs (30–100 m in large ground-mount arrays) demand lower resistance to control I²R losses. The tinned conductor also prevents the electrochemical corrosion that occurs between bare copper and the tin-plated MC4 crimp pins over decades of wet-weather exposure.

A 6 mm² solar cable at 90°C conductor temperature in free air has a nominal ampacity of approximately 46A — well above typical string currents of 10–20A. For voltage drop, use the formula: VΔ = (2 × L × I) / (56 × A), where L is one-way string length in metres, I is string current in amps, and A is conductor cross-section in mm². The factor 2 accounts for the return conductor. Target VΔ below 1% of string voltage for optimal system performance.
