Half-cell configuration of the JA PV modules offers the advantages of higher power output, better temperature-dependent performance,reduced shading effect on the energy generation.
Solar modules stand out with the breakthrough innovation of M10 size (182mm) solar cells for the highest power generation and the lowest LCOE, which makes 182mm solar module the optimal choice for large solar power system.
The current maximum efficiency of TOPCon mass production has been stabilized at 25%, and it is expected to quickly break through 26.1%, and the yield rate can be increased to 98%.
The ultra-thin tunnel layer, N-type poly-Si thin film layer can greatly reduce the loss caused by carrier recombination. Cell conversion efficiency is up to 25%.
The first-year degradation rate 2%, annual linear degradation rate 0.45%, life cycle 225 years By comparison, N-TOPCon modules will bring 1.8% extra power generation gain.
