380W Black Frame Solar Roof Tiles Panel with High Efficiency for Solar Power Energy PV System

This solar module use multi-bus bar technology, which can shorten the current conduction distance by more than 50% and lower the internal ribbon resistance loss. With finer and narrower bus bars, more sunlight will be reflected back from the round ribbon and onto the cell, thus increasing solar panel efficiency. The unique circuit design of half-cut cells can reduce power loss to 1/4 compared to full cells solar PV module, which results in a decrease of electrical resistance within the ribbon and finally improves the overall module efficiency by up to 0.6%.

Technology

The PERC cell has a passivated rear side and a laser grooving process, which significantly improves the cell efficiency.
	Half-cut cell is to cut the cell into two seperate parts by mature infrared laser, hence halve the working current. The thermal loss on the ribbon will be remarkably reduced and the module's power increases. The reliability of module is also enhanced.The combination of half-cut cell technology and bifacial module can amplify the gain over the effect of current-reduction.
