SALIENT FEATURES
Convergence of cutting-edge technologies
This panel is equipped with the most advanced technologies in the field today. Here are four technologies that have made this product line famous:
- Half-cut cells: With this technology, the battery cells are cut in half, so the number of independent battery cells will be doubled, from 72 to 144 battery cells on the same panel size. Thereby reducing the current to help the panel stay cooler when operating, thereby increasing the efficiency of photovoltaic conversion. In addition, these factors also help the panel have a longer life than usual.
- PERC: PERC technology stands for Passivated Emitter and Rear Cell. PERC helps improve the efficiency of the solar panel by allowing electrons to move more easily while increasing the reflectivity of light at the back of the solar cell, which converts a larger amount of light energy than conventional.
- Multi Busbars: The busbar acts as the main path leading electrons from the battery cell to the external circuit to form an electric current. With a battery cell with many busbars, electrons are more easily concentrated to form an electric current. So the panel uses a lot of thin metal wire to conduct the current, which will be stable and less consumed.
- Split panel: This technology splits the panel into 2 independent parts. Instead of the traditional type, if a part of this panel is shaded, the whole panel will be affected. Now, the level of influence will be halved, because the panel has been cut into 2 parts to operate independently.
