ADC Solar Wire and Cable
Advanced Digital Cable (ADC) has manufactured wire and cable in the USA since 1997, running an ISO 9001:2015 registered quality system across three plants in North Carolina and Georgia. PowerStore carries ADC Solarlink PV wire, bare copper ground wire, and THHN/THWN-2 building wire.
American-Made Wire for Solar Projects
ADC's Dual Pass PV wire puts chemically cross-linked XLPE insulation under a colored sunlight-resistant PVC jacket, so one cable handles exposed outdoor runs, wet locations, and direct burial.

Top ADC FAQs with Jim White
What is the difference between PV wire and THHN?
PV wire uses sunlight-resistant XLPE insulation rated for direct burial and exposed outdoor runs. THHN is PVC and nylon building wire made for conduit. Use PV wire for interconnects, THHN for protected circuits.
Should I buy 2000V or 600V PV wire?
Match the rating to your system's maximum DC voltage. Residential string systems under 600 volts run fine on 600V wire, while commercial and utility arrays with higher DC bus voltages need the 2000V rating.
Can ADC PV wire be buried underground?
Yes. ADC Dual Pass PV wire is UL listed for direct burial with no conduit required. The XLPE core and sunlight-resistant jacket are rated 90C wet and 105C dry, from trench to full sun.
