Tier 1 Residential Module integrates various technologies like half-cut and multi busbar (MBB) cells. MBB can shorten over 50% of the current conduction distance and thus lower the internal ribbon resistance loss. With finer and narrower busbars, more sunlight can be reflected back to the round ribbon, thus increasing energy efficiency. Besides, the unique circuit design of half-cut cells can reduce power loss to 1/4 compared to full cells, which results in a decrease of electrical resistance and finally improves the overall module efficiency by more than 2%.
Tier 1 products have always maintained high reliability and solid performance based on rigorous raw material selection and full value chain control of the production line. With the high standard and systematic quality control.
Tier 1 Residential Module adopts half-cell technology. Two pieces of half cells are connected in series, the power loss caused by ribbon resistance is reduced to 1/4 of that in full cell, which results in decreasing of electrical resistance within the ribbon and finally improves the overall efficiency of module by more than 2%.
