Product Overview
The JinkoSolar Tiger Neo 620W is a high-output N-type monocrystalline solar panel featuring TOPCon cell technology, bifacial power generation and a durable dual-glass construction. With a rated module efficiency of 22.95%, it is designed for photovoltaic installations where strong power density, long-term performance and rear-side energy generation are important.
Key Features
- Delivers 620 W maximum power with a module efficiency of 22.95% under Standard Test Conditions.
- N-type TOPCon and HOT 3.0 cell technologies support efficient operation, improved low-light performance and reduced LID/LeTID degradation.
- Bifacial construction can generate additional power from light reaching the rear of the module, depending on the installation and surrounding surface.
- Dual-glass design uses 2.0 mm anti-reflective front glass and 2.0 mm heat-strengthened rear glass.
- SMBB technology improves light capture and current collection to support module output and reliability.
- Certified for maximum static test loads of 5400 Pa on the front and 2400 Pa on the rear.
- Positive power tolerance of 0 to +3%.
- IP68-rated junction box provides protection against dust and water ingress.
Applications
- Large roof-mounted or ground-mounted photovoltaic arrays designed for the module's dimensions, weight and electrical characteristics.
- Bifacial installations where reflected light can reach the rear of the panel.
- Solar systems operating at up to 1500 V DC, subject to appropriate string design and equipment compatibility.
Why Choose This Product?
The Tiger Neo 620W combines high power output with N-type TOPCon technology and bifacial dual-glass construction. Its 22.95% efficiency helps installers achieve substantial array capacity using a high-output module, while its low power temperature coefficient supports performance under elevated operating temperatures. The manufacturer also specifies a 12-year product warranty and a 30-year linear power warranty, subject to the applicable warranty terms.
Important Notes
- The 685 W BNPI rating is measured with additional rear-side irradiance under specified laboratory conditions. Actual bifacial gain will depend on mounting height, tilt, shading, ground reflectivity and site conditions.
- Connector options may include JK03M, MC4 or another specified connector. MC4 and MC4-EVO2 are available on request and subject to availability; confirm the connector supplied before installation.
- Confirm the exact orderable 620 W product code against the supplier documentation before publishing.
- String voltage, current, fuse protection, mounting loads and inverter compatibility must be checked during system design.
- Installation must be completed in accordance with the JinkoSolar safety and installation manual by a suitably qualified solar installer or electrician.
