This 100 metre reel of 10mm² solar PV DC cable is a single-core H1Z2Z2-K cable built to the EN 50618 and IEC 62930 photovoltaic cable standards, designed for wiring between solar panels, DC combiners, and inverters in UK PV installations.
The cable is halogen-free, flame-retardant and low-smoke, with an XLPO (cross-linked polyolefin) insulation and jacket that is fully UV- and ozone-resistant, giving it an anticipated service life in line with the 25–30 year lifespan of a modern solar array.

Certified Standard
TÜV-Approved to EN 50618
Certified to the EN 50618 (H1Z2Z2-K) and IEC 62930 international standards for photovoltaic wiring.
Halogen-Free & Flame Retardant
Low-smoke, halogen-free construction means the cable will not emit toxic fumes in the event of a fire, tested to EN 60754-1 and EN 60332-1-2.
UV & Ozone Resistant
XLPO insulation and jacket are fully weather, UV and ozone resistant, tested to EN 50289-4-17 for permanent outdoor exposure.
25+ Year Service Life
Electron-beam cross-linked XLPO construction gives the cable an anticipated service life of 25–30 years, matching the working life of a solar PV system.
High Current Carrying Capacity
Rated to carry 98A when exposed in free air, dropping to 79A on surfaces with contact and 61A in conduit — more than sufficient for typical string and DC main runs.

Important Safety Information
This cable is for DC use only and must never be disconnected under load. Isolate the DC side of the PV system fully before connecting or disconnecting any cable runs.
Good to Know
Also available as a 500m reel in black, and in both 100m and 500m lengths in red, for correct positive/negative polarity identification across your installation.
What is H1Z2Z2-K cable and why is it used for solar panels?
H1Z2Z2-K is the European standard designation for single-core, double-insulated, halogen-free photovoltaic cable certified to EN 50618. It is the industry-standard cable type for DC wiring between solar panels, combiners and inverters across UK and EU installations.
Is this cable suitable for outdoor use?
Yes. The cable's XLPO insulation and jacket are UV and ozone resistant and rated for continuous outdoor exposure across an operating range of -40°C to +90°C, with an anticipated service life of up to 30 years.
Can this cable be used both for panel-to-panel and DC main runs?
Yes. At 10mm², this cable is commonly used both for interconnecting PV modules/strings and for longer DC main cable runs from the array combiner to the inverter, where the larger cross-section reduces voltage drop over distance.
What connectors are compatible with this cable?
10mm² H1Z2Z2-K cable is compatible with standard MC4 and MC4-compatible solar connectors rated for 10mm² conductors — confirm your chosen connector's crimp barrel size matches this cable's conductor diameter before ordering.
Do I need to run cables in red and black for polarity?
Best practice for DC PV wiring is to use one black cable for negative and one red (or clearly marked) cable for positive to maintain clear polarity identification throughout the system, in line with standard UK wiring practice.
What's the difference between the 100m and 500m reel?
Both reels contain the same 10mm² H1Z2Z2-K black cable to the same specification — the only difference is the length supplied per reel, allowing you to size the purchase to the scale of your installation.
