https://www.solar-off.com/shopdetail/000000000659 HPBC technology, which is designed without wiring on the cell surface, achieves high solar absorption rate and excellent power conversion efficiency! “JET Series 450W BSM450M10-54NHS” uses the latest technology “HPBC”, which is characterized by a design in which wiring on the surface of the cell, such as bus bars and finger electrodes, is placed on the back side. This technology eliminates the effects of shading, improves sunlight absorption rate by approximately 2.27% compared to conventional PERC modules, and achieves an excellent power conversion efficiency of 23%, so it can be used even when exposed to high temperatures or cloudy conditions. Demonstrates high power generation performance even under low light conditions. In addition, because the wiring is connected in a straight line on the back side, there is less risk of cell cracking, and it also features a clean and beautiful appearance. Furthermore, the deterioration speed is extremely slow, and the output is guaranteed to be 86.9% over 30 years.

In addition, our output is about 20W higher than similar products, and the maximum output is 450W, which is one of the points. In the future, in view of the increasing demand for all-black products, we plan to develop a full-black series with black front and back sides that will blend in well with residential roofs.

●High-efficiency JET cell promotes new technological innovation [Sunlight absorption] Multilayer anti-reflection coating maximizes sunlight intake. There are no wiring (bus bars or fingers) on the front side, and there is no shading, maximizing sunlight absorption. [Transmission of electrical energy] Stable power transmission is achieved using technology that places and – electrodes on the front side. [Conversion of light energy to electrical energy] Conversion efficiency is improved by suppressing recombination of impurities using a multilayer passivation film. [PRO] PRO hydrogen passivation process repaired micro lattice defects and exceeded the limit of module conversion efficiency.

●Multi-angle incidence/non-shading absorption Since there are no wiring (busbars or fingers) on the surface, it increases the absorption of oblique light. [JET module] When there is no wiring on the surface: There is no shading, maximizing sunlight absorption. [PERC module] When there is wiring on the surface: There is light shielding and a small shadow area exists.

●The power temperature coefficient is as low as -0.29%/℃, which suppresses output drop even at high temperatures, so stable power generation is possible even under high temperature conditions. [Image 6

●Relative power generation performance is good even in low illuminance [Image 7

●Ensures lower output deterioration and guarantees a 30-year output guarantee.30-year output guarantee: If the output falls below the standard, we will replace the main unit or provide an equivalent product.
