Trustworthy High Efficiency Poly Half-cell perc 280W-340W Solar panel
(We Are Factory) New type half cell 325-500W Mono Perc Solar Panel with CE/TUV certificate, 30years warranty.
In recent years, with the rapid development of photovoltaic technology and its wide application range, the market has changed from focusing only on high power to combining high power, high power output, low attenuation and low cost under any installation conditions, thereby further reducing the cost of electricity. So how to reduce the cost of electricity has become the most core issue in the industry, and as the core component of the photovoltaic system end-to-end power generation, how to improve the output of photovoltaic component is the most important.
Half-cell technology is by cutting the standard cell sheet 156mm*156mm laser into two pieces of 156mm*78mm, and connect together. The cells of the whole module are then divided into two groups, 72 half-cells connected in series. A complete 144 pieces assembly reduces the current through each fate to 1/2 and the internal loss to 1/4 of the entire cell, thereby increasing the power the module.
The advantages of the half- cell Perc solar panels.
Assembled by high-efficiency Perc cells, the half-cell configuration of the modules offers the advantages of higher power output, better temperature-dependent performance, reduced shading effect on the energy generation, lower risk of hot spot, as well as enhanced tolerance for mechanical loading.

5.Advantages:
Less Mismatch loss:Instead of 6 internal strings of cells, the half cell series module has 2 x 6 shorter ones. This design effectively deals with the mismatch happened between cells caused by shadow, out of sync performance degradation, ect.
