Commercial and industrial rooftop PV systems offer building owners and occupants a clean and increasingly affordable option. As a result, the rooftop solar installation market is growing exponentially across the globe. The photovoltaic system on the European roof must meet the requirements of the CPR (Construction Product Regulation), all our solar cables must not only meet the H1Z2Z2-K, EN50618TUV certification, IEC62930 certification, and UL. but also meet the CPR (Construction Product Regulation) fire standards, LEADER solar cable has CPR: Cca-s1b, d2, a1 certification based on the EN 50575 standard. Our solar connectors also have TUV, UL, and CE certification, which meets the safety level protection requirements of industrial and commercial photovoltaic systems for fire protection.
