Solar cables on PV plants during high temperatures


High temperatures can affect different components of PV systems. Inverters can fail, the efficiency of solar modules can decline, and existing cell damage can become worse. Cables only represent around 4-5% of a solar project cost, but it can have a significant impact on the power output. Cabling is often not considered to be a critical factor. However improper design and/or poor cable selection can lead to safety hazards, reduced power output, and other performance issues that may jeopardize the overall lifetime of a PV system.

AN INAPPROPRIATE SOLAR CABLES SELECTION CAN LEAD TO PERFORMANCE PROBLEMS IN THE PHOTOVOLTAIC SYSTEM.

To maintain the longevity and reliability of the PV system, cables used in solar generation must be designed to provide excellent performance during prolonged exposure at high temperatures and withstand harsh environmental conditions like long-term exposure to ozone and sunlight, extreme temperature fluctuations and direct ultraviolet (UV) rays.

720-CYCLE UV RESISTANCE TESTS

Top Cable has specifically engineered superior performance PV cables that resist to UV rays, ozone, sand abrasion and water absorption. As well as provide excellent flexibility for extreme weather conditions during prolonged exposure at sunlight.

TOPSOLAR® H1Z2Z2-K  cable is TÜV certified according to EN50618 and AENOR certified according to IEC 62930, surpassing the most aggressive UV resistant tests of both standards,  including two different UV rays tests from two accredited laboratories.
