Solar PV Wire - 10 AWG XLPE Insulation - RPVU90 Red - 10PVU90R

What this product is for

This product is a 10 AWG single-conductor photovoltaic wire for solar array wiring, string extensions, and exposed outdoor DC runs where RPVU90-type XLPE insulation is required. It is suited to Canadian solar work where cold-weather flexibility, sunlight resistance, and wet-location performance matter.

Use for

Use for PV module string wiring, homeruns to combiner equipment, and other solar interconnections where 10 AWG PV wire is specified. Typical comparable RPVU90 listings show XLPE insulation, sunlight resistance, direct burial suitability, and operation from -40 degC to 90 degC wet or dry.

Avoid for

Avoid using this wire where a multi-conductor cable assembly, armoured cable, or building wire is required instead of single-conductor PV wire. Do not assume connector type, conductor stranding, voltage class, or reel length from the SKU alone.

Best for

Best for solar contractors and electricians needing 10 AWG PV cable for rooftop or ground-mount systems in exposed Canadian conditions. It is commonly used where UV exposure, moisture, and low-temperature installation are expected.

Installed in

Installed in solar arrays on homes, farms, cabins, commercial rooftops, and ground-mount systems. Depending on system design, it may be run in free air, cable tray, or raceway, and some comparable products are listed for direct burial where permitted by code and installation method.

Why this product exists

PV wire uses insulation designed for solar environments where standard building wire may not be suitable for prolonged UV exposure and outdoor wet conditions. For Canadian installations, the supported RPVU90 references indicate a wire type intended to handle cold starts down to approximately -40 degC while maintaining a 90 degC wet or dry insulation rating.

Compared with similar products

Compared with smaller 12 AWG or 14 AWG solar wire, 10 AWG is commonly selected to reduce voltage drop on longer runs, subject to system current and design. As a rule of thumb for low-voltage solar circuits, longer runs often move from 16 AWG to 14 AWG to 12 AWG, while 10 AWG is a common step where current or distance is higher. Actual performance depends on run length, current, temperature, installation method, and local electrical code.
