Photovoltaic cable operates in outdoor environments where sunlight, temperature cycles, moisture and mechanical handling can affect long-term performance.

In addition to rated DC voltage, project teams should review conductor construction, insulation and sheath materials, UV resistance, water resistance, temperature range and compatibility with the selected connectors.

Rooftop, utility-scale and floating PV installations can present different risks, so one general specification should not be assumed suitable for every solar project.
