Trina Solar Vertex S all black 415wp Trina Solar Vertex S all black 415wp solar panels are the new solar panels with an exceptionally high power . These solar panels have a black backsheet, monocrystalline, black cells and a black frame. To obtain such a high power, the Trina Vertex S all black 420wp solar panel is equipped with 10 wafer-thin connection ribbons per series of cells and they have been given a specific shape, which ensures that the sunlight is evenly distributed over the cells. The connection ribbons and the 144 half cells in the Trina Solar Vertex S solar panel have also been placed closer together. This is also referred to as high density interconnect technology . The advantage of this is that more of the available surface area is used to install solar cells. In addition, it lowers the resistance in the solar panel. Together, this results in an efficiency of up to 21%! The half-cell design also ensures that the solar panel deals better with shade and that it suffers less from resistance because the distances are shorter. Finally, the Trina Vertex S solar panels have a low temperature coefficient and working temperature, so heatis no problem for these Trina Solar Vertex solar panels. Guarantee The company was founded in 1997 and is now the world leader in the field of solar panels. Trina is consistently at the top of Bloomberg's Tier 1 list. They have the entire process from ingot to wafer, to cell and finally to solar panel under their own management and extensively test their products during the entire process on the basis of TUV and MCS certificates. The Trina Solar Vertex 415wp solar panels are produced in a special Vertex factory. It doesn't get much more professional! Trina Solar offers a 15-year product warranty and a 25-year linear yield warranty up to 84.8% on the Trina Solar Vertex 415wp solar panels.
