620W Solar Panel

A: The power output range is 595W-620W, using N-type 182mm half-cell cells, with a maximum conversion efficiency of 24.0%, which is about 2-3 percentage points better than the mainstream P-type modules, and has higher power generation under the same area.

A: Half-cell technology cuts a single cell into two halves and connects them in series through multi-busbar (MBB) technology. Advantages include:

    Reduced current loss and increased power output by 5%-7%;

    Reduced shadow shading (such as bird droppings, snow accumulation), increased power generation by 3%-5%;

    Reduced hot spot risk and increased module life;

    Enhanced mechanical load tolerance and stronger resistance to hidden cracks.

A: It supports bifacial power generation (models contain the "Bifacial" logo). The back gain depends on the ground reflectivity (such as about 10%-15% for grass and 20%-25% for snow). The comprehensive power generation can be increased by 10%-20% in scenarios such as agricultural photovoltaic complementarity and water surface photovoltaic.

A: It is suitable for ground power stations, industrial and commercial roofs, and household photovoltaics:

    Industrial and commercial/household: frameless double-glass design (thickness 35mm), suitable for color steel tiles, concrete, and ceramic tile roofs, weighing about 29.5kg, and can be carried and installed by one person;

    Ground power station: high power density reduces the number of brackets, compatible with fixed tilt angles, flat single-axis tracking brackets, and supports 1500V high-voltage systems (customization required).

A: It has passed the IEC 61215 mechanical load test, wind pressure resistance of 5400Pa (can withstand a level 17 typhoon), snow pressure resistance of 3600Pa (withstands 1.5 meters of snow), and has passed the salt spray (1000 hours) and ammonia (1000 hours) tests, making it suitable for corrosive environments such as coastal high humidity and agricultural greenhouses.

A: The operating temperature range is -40℃~+85℃, and the temperature coefficient is -0.29%/℃ (better than the conventional P-type module's -0.35%/℃). The power decay is slower in high temperature environments, and the power generation in deserts and tropical areas is 2%-3% higher than similar products.

A: We provide a 12-year product warranty (free replacement for broken glass and junction box failure) and a 30-year linear power warranty:

The attenuation in the first year is ≤1%, and the attenuation each year thereafter is ≤0.4%. The power in the 30th year is ≥87.4% (the industry standard is a 25-year warranty, and the 25th year is ≥80%).

A: The double-glass structure has a smooth surface and strong resistance to dust adhesion. It is recommended to clean it 1-2 times a year (depending on the local wind and sand conditions). The frameless design reduces dead corners for dust accumulation, and with drone inspections (optional), the operation and maintenance costs are 20% lower than traditional components.

A: The half-cell + multi-busbar design divides the battery into independent circuits. When a single battery cell is affected by the shadow, it only affects 1/2 of the circuit. Compared with the whole battery (affecting the entire circuit), the power generation loss is reduced by more than 50%.

A: It has passed IEC 61215, IEC 61730, and UL 1703 certifications, supports EU CE, Japan JET, Australia CEC and other access standards, and is suitable for mainstream photovoltaic markets around the world (including the United States, Europe, Southeast Asia, etc.).

A: The size is 2278×1134×35mm, and the installation holes meet the industry's mainstream 182mm battery component standard. It is compatible with 95% of photovoltaic brackets on the market (such as GoodWe and Trina brackets), and no special customization is required.

A: It supports compatibility with mainstream brand inverters (such as Huawei and Sungrow), and the output voltage range is compatible with 1000V/1500V systems (the inverter specifications need to be confirmed). It is recommended to use the same model of components in the same project to optimize the series-parallel design.

A: It uses lead-free solder strips and ECO certified EVA film, meets RoHS environmental standards, glass recycling rate ≥90%, and aluminum frame is 100% recyclable. Jingsun provides module recycling guidance, and some regions support paid recycling services.

A: Lower levelized cost of electricity (LCOE): high bifacial gain and low attenuation rate (≤1% in the first year) increase power generation by 5%-8% in a 25-year cycle, and LCOE is 2%-3% lower than conventional modules;

    BOS cost savings: 620W high power reduces the number of brackets, cables, and inverters, and the system cost is reduced by about US$0.007/W.

A: It supports third-party IoT module integration (customization required). By scanning the QR code of the component, you can view the real-time power, historical attenuation curve and EL test report. Combined with the power station management platform, the operating status of each component can be remotely monitored.
