    Lower degradation,
    Longer Warranty

    Compared with traditional PERC modules, HY SOLAR HT series N-type modules have 15-year product workmanship warranty, and up to 30-year linear power warranty, with less than 0.4% of annual degradation. It is guaranteed that the output power would be no less than 87.4% of the initial output after 30-year operation.

    SUPERIORITIES OF HT MODULES

  • 01

    Cutting-edge TOPCon Tech

    HY SOLAR TOPCon cell applies PECVD poly tech, high-efficiency SE tech and multi-layer dielectric film structure tech, which can reduce series resistance and grid silver consumption effectively, and also improve the tolerance for broken grid line, microcrack and breakage, to increase the cell efficiency.

  • 02

    Diverse Module Types

    Providing module products that are suitable for different scenarios to clients, with the consideration of balancing the module weight and their performance. 54 pcs, 60 pcs, 66pcs, 72pcs and 78 pcs are all available for HT modules.

  • 03

    SMBB & Half-cell Tech

    SMBB tech optimizes the grids spacing, shortens the current transverse transmission path, so that series resistance can be reduced, resulting in 1.5% improvement in efficiency compared with traditional 5BB modules. This can ensure the overall power generation for utility-scale solar power plants, to obtain a stable return.

  • 04

    Non-destructive Cutting Tech

    Applying low temperature non-destructive cutting tech, therefore there is stress difference on the surface of the cell for automatically being broken into two halves. The cross section of the cell cut by non-destructive cutting technology is smooth without burrs, thus the quality of the module can be obviously improved.

  • 05

    High Density Cells Encapsulating

    After the welding strip forming, internal stress can be eliminated by anneal with all-in-one segmental welding strip technology applied, to improve the product realiability. Additionally, there is a reduce in the cell spacing from 2.0mm(in traditional manner) to 0.8mm, realizing the micro-distance interconnection of the cells, thus improving the efficiency.

  • 06

    Higher Bifaciality

    The bifaciality of HT modules can reach 80%-85% by optimizing their backside film structure, which is more than 10% higher than that of PERC modules. According to calculation, HT modules has 2% backside generation gain compared with PERC modules.

  • 07

    Lower Temperature Coefficient

    Applying TOPCon cell of high Voc to reduce the temperature sensitivity of cell. HT module temperature coefficient is -0.29%/℃, which can promote higher power generation and thus increase the yield of power plant.

  • 08

    Better Low-irradiance Performance

    Due to the excellent design of cell internal resistance, it enables minority charge carriers have longer lifetime, so that modules could perform better in low irradiance, especially below 600W/㎡. HT modules could help extend the effective working time of a power plant by 1 hour every day on average, 0.2% higher than that of PERC modules.

  • 09

    Lower Degradation

    TOPCon cell is phosphorus-doped. As a result, it does not lead to boron-oxygen complexes, which cause recombination centers and contribute to LID. Moreover, N-type silicon wafers have longer carrier lifetimes and greater tolerance to metal contamination, resulting in lower LeTID. Consequently, the performance of TOPCon module products is more stable and has lower first-year degradation.

  • 10

    Lower LCOE

    Lower degradation, lower temperature coefficient, higher bifaciality and better low-irradiance performance, leading to a great improvement in power generation.
