HJT Solar Panels

    Efficiency: Using N-type HJT technology, the conversion efficiency reaches 23.2%, which is higher than traditional PERC cells (about 22%) and Topcon (about 23.5%).

     Weight: 38.5kg, lightweight design is easy to carry and install.

    Lower temperature coefficient: The temperature coefficient is - 0.24%/℃, and the power loss in high temperature environment is more than 30% lower than PERC.

    Bifacial power generation: Supports bifacial power generation, and the power generation gain on the back can reach 10%~30%, which is suitable for ground or water scenes with high reflectivity.

    Anti-corrosion design: It adopts a double-glass structure (2.0mm tempered glass) with strong weather resistance, suitable for harsh environments such as high humidity and salt spray.

    Warranty: Provide 30-year linear power warranty (attenuation ≤2% in the first year, ≤0.45% per year thereafter) and 12-year product warranty.

     Installation angle: The optimal inclination angle is 15°~30°, which needs to be adjusted according to the local latitude and meteorological data.

     Spacing requirements: The spacing between components is recommended to be ≥30cm to avoid occlusion between the front and rear rows.

A: Compatibility: It can be connected to a third-party intelligent monitoring system (such as Huawei, Sungrow Power Supply), and supports remote real-time monitoring of power generation, fault warning and other functions.

     Data interface: RS485 interface is standard, supports Modbus protocol, and can be linked with the energy storage system.

A: Power matching: It is recommended that the inverter capacity is 1.2~1.5 times the total power of the components (for example, a 10kW system requires a 12~15kW inverter).

     MPPT voltage range: needs to cover the operating voltage range of the components (Vmp=42.10V, Voc=50.19V).

     Recommended models: Huawei SUN2000-10KTL-M1, Growatt SPH10000, etc.

A: High open circuit voltage: Voc reaches 50.19V, faster startup in low-light environment, and power generation in the early morning/evening is 10%~15% higher than PERC.

     Half-cell technology: 132 half-cut cells reduce current transmission losses and increase efficiency by 5%~8% under low irradiance.

A: Cleaning frequency: It is recommended to clean once a quarter, rinse with a soft cloth or water gun to avoid scratching the glass.

     Avoid chemicals: Do not use acidic or alkaline cleaners to avoid corrosion of AR coating.

     Troubleshooting: If the glass is broken or the junction box is abnormal, you need to immediately cut off the power and contact after-sales for replacement.

A: Working temperature: -40℃~+85℃, suitable for extremely cold and high temperature areas.

     Anti-PID ability: HJT technology is naturally resistant to potential induced degradation (PID), and no additional protective measures are required.

    Fire protection level: Meets UL 94 V-0 fire protection standard, suitable for sensitive areas such as roofs.

A: Packaging: 31/36 pieces per pallet, reinforced with pearl cotton and wooden boxes to prevent vibration damage during transportation.

    Storage environment: It needs to be stored in a dry and ventilated place, avoid direct sunlight, and the stacking height should not exceed 5 layers.

A: International certification: Passed TÜV, IEC 61215, IEC 61730, UL 1703 and other certifications, suitable for markets such as Europe, the United States, and Australia.

     Domestic certification: Meets China Golden Sun Certification (CGC) and CQC standards.

A: Cost: The current price is about $0.13/W (market price in 2025), and the cost of a 720W component is about $93.6.

     Power generation: Taking Florida, the United States as an example, the average annual power generation is about 1300kWh/block, and the electricity bill is saved by about $150/year.

     Payback period: About 6~8 years (including 30% federal tax credit).

A: Federal Tax Credit (ITC): US users can enjoy a 30% federal tax credit, which is valid until 2032.

     Net metering policy: Florida and other states support 1:1 net metering, and the surplus electricity is deducted from the electricity bill at the retail price.

     Local subsidies: Some states provide additional subsidies (such as California $0.75/W), and you need to consult the local energy department.

A: Global service network: Jingsun has more than 20 offices around the world, providing 7×24 hours technical support.

     Fault response: Provide solutions within 48 hours, and send replacement parts within 72 hours.

     Warranty coverage: 30-year power warranty covers material and workmanship defects, and 12-year product warranty covers component damage.
