Our Partners
At Celestix Industries India Pvt. Ltd., we don’t just build solar cable assemblies—we engineer photovoltaic wiring harness solutions that deliver reliability, efficiency, and long-term performance. Designed for utility-scale solar farms, rooftop solar systems, grid-tied and off-grid microgrids, solar tracking systems, and advanced battery energy storage (BESS), our assemblies are tested to withstand the harshest real-world PV environments.
Our solar wiring harnesses, PV cable assemblies, and custom solar connectors are built using XLPE, TPE, and flame-retardant materials, ensuring UV resistance, thermal endurance, and mechanical durability. With EN 50618 compliance, UL/TUV/BIS certifications, and RoHS/REACH adherence, Celestix enables OEMs and EPCs to scale faster, safer, and smarter.
Why Solar Cable Assemblies Fail—and How Celestix Prevents It
Our assemblies are torque-validated, EMI shielded, flame-retardant, UV-tested, and hipot-certified, delivering decades of field reliability across rooftop, utility, and hybrid solar projects.
