Technical Insights

Key Characteristics of Solar Cables

Solar cables are specially engineered for UV resistance, flame retardance, high dielectric strength, ozone resistance, and wide temperature tolerance. They are typically insulated with cross-linked polyethylene (XLPE) or ethylene propylene rubber (EPR), ensuring durability in outdoor conditions.
Voltage Range: Most solar cables operate within 600V to 2000V ranges.

Temperature Resistance: Designed to function between -40°C and +120°C, supporting harsh climate conditions.

Conductor Material: Copper and aluminum are commonly used, with copper dominating due to higher conductivity.

Types of Solar Cables

DC Solar Cables – Connect solar panels to inverters, optimized for low-voltage applications.

AC Solar Cables – Transmit power from inverters to the grid.

Battery Cables – Used in off-grid and hybrid solar installations.

String & Array Cables – Connect multiple solar panels in large solar farms.
