System Bifacial Solar Panels

 

Increased Efficiency. As bifacial modules can produce powers from both sides of the panel, there is an overall increase in energy generation. Some manufacturers claim that bifacial solar panels can generate up to 30% more energy than conventional monofacial solar panels.

 

 

 

A bifacial solar cell (BSC) is a photovoltaic solar cell that can produce electrical energy when illuminated on both its surfaces, front or rear. Instead, monofacial solar cells only produce electrical energy when photons impinge on their front side.

Product description

 

The Heterojunction Technology (HJT) combines high efficiency with a simple design reducing the number of manufacturing steps and achieving an important cost reduction. It combines the advantages of mono crystalline silicon solar cells with the good absorption and the superior passivation characteristics of amorphous silicon leading to a higher efficiency.

Compared with other ultra high-efficiency solar cell, HJT solar cell is manufactured in less procedures.

The compact and lightweight dual-glass module with 2.0mm tempered glass was successfully developed in 2014. Now, thinner, lighter dual-glass module with 1.6mm tempered glass encapsulated with high efficiency HJT solar cell can be produced. Due to the material and structure characteristics, dual-glass module fundamentally avoid defects such as PID, micro cracks of cells, and snail trail ,which can reduce the investment cost, transport cost and the operation risk of power plants, etc. At the core of the photovoltaic facility are solar panels.

The photovoltaic system can be installed on the surface of the earth in a large scale to become a photovoltaic power station. It can also be placed on the roof or outer wall of a building to form the integration of photovoltaic architecture.
