High Quality 550w Mono Bifacial Panels 182mmm Cell Ronma Brand Bifacial Solar Panel

Short Description:

The packaging technology of ronma solar panel Dual Glass Solar cells can be divided into Dual Glass Solar Module and  Dual Glass Solar Module(with frame) . The layout ofDual Glass Solar Module includes:  Dual Glass + frameless layout; Dual Glass Solar Module (with frame) The components adopt transparent backplane + frame form, etc. The  Dual Glass Solar Module with confluence structure has the advantages of long life cycle, low attenuation rate, weather resistance, high fire resistance, good heat dissipation, good insulation, easy cleaning, and higher power generation efficiency.

Product Features

1) The back can generate electricity. The back of the Dual Glass Solar Module can use the reflected light from the ground to generate electricity. The higher the reflectivity of the ground, the stronger the light absorbed by the back of the battery, and the better the power generation effect. Common ground reflectances are: 15% to 25% for grass, 25% to 35% for concrete, and 55% to 75% for wet snow. Dual Glass Solar Module can increase power generation by 8% to 10% when used on grassland, and can increase power generation by 30% when used on snowy ground.

2) Accelerate the snow melting of components in winter. Conventional photovoltaic modules are covered with snow in winter. If the snow cannot be cleared in time, the modules will easily freeze in the continuous low temperature environment, which not only seriously affects the power generation efficiency, but also may cause unpredictable damage to the modules. On the other hand, after the front of the Dual Glass Solar Module is covered with snow, the back of the module can absorb the reflected light from the snow to generate electricity and generate heat, which accelerates the melting and sliding of the snow and can increase the power generation.

3)Dual Glass Solar Module. ronma Dual Glass Solar Module. Dual Glass Solar Module can reduce the consumption of combiner boxes and cables in 1500V photovoltaic system, and reduce the initial system investment cost. At the same time, because the water permeability of the glass is almost zero, there is no need to consider the problem of the output power drop caused by the PID induced by water vapor entering the module; and this type of module is more adaptable to the environment, and is suitable for construction in places with more acid rain or salt spray Photovoltaic power plants in the region.

4) The placement of bias and naivety. Because the front and back of the module can receive light and generate electricity, the power generation efficiency under the vertical placement condition is more than 1.5 times that of the general module, and it is not affected by the installation bias, and it is suitable for places where the installation method is limited, such as guardrails, sound insulation walls, BIPV system etc.

5) Additional support forms are required. Conventional brackets will block the back of the Dual Glass Solar Module, which not only reduces the back light, but also causes series mismatch between cells in the module, affecting power generation results. The support of the double-sided photovoltaic module should be designed in the form of a "mirror frame" to avoid covering the back of the module.
