The Jinko 550W Mono Crystalline Half Cell panel is part of Jinko’s Tier-1 solar module lineup, engineered to deliver strong energy production and dependable operation under a variety of environmental conditions. This panel utilises half-cell monocrystalline silicon technology, which improves power output and reduces resistive losses compared with traditional full-cell designs. By splitting each solar cell in half, electrical pathways are shorter, which enhances efficiency and reliability while also reducing the impact of shading and hot-spots on overall performance.

At Standard Test Conditions (STC), the module produces a maximum rated power of 550 W with a module efficiency of approximately 21.29 %, making it a strong choice where space is limited and high wattage per panel is needed. The panel’s maximum power voltage (Vmp) is about 40.90 V, with a current at maximum power (Imp) of 13.45 A, and its open-circuit voltage (Voc) is 49.62 V. These electrical characteristics make it compatible with a wide range of inverters and system configurations.

Mechanically, the JKM550M-72HL4-V features quality construction suited for long-term outdoor exposure. The module uses 3.2 mm AR-coated tempered glass and an IP68-rated junction box, offering protection against dust and moisture ingress. The aluminium frame is designed to withstand significant mechanical loads, including high wind and snow pressure. It’s certified to international safety standards like IEC 61215 and IEC 61730, ensuring reliability and compliance with global safety requirements.

In terms of environmental tolerance, this panel performs over a wide temperature range from -40 °C up to +85 °C, and its maximum system voltage rating goes up to 1500 VDC — suitable for larger string arrays in commercial installations.

Warranty coverage is another strong aspect: typically, it includes a 12-year product warranty and a 25-year linear power output warranty, wherein the panel’s power generation is guaranteed to remain high with minimal annual degradation. This long-term assurance is important when evaluating total lifetime value and return on investment for solar projects.

Overall, this Jinko 550W panel is designed to balance high power output, solid efficiency, and durable construction, making it a compelling option for those aiming to install efficient and reliable solar arrays for medium to large-scale energy needs.
