Our manufacturing facility covers an area of approximately 10,000 square meters. It incorporates 8 fully automatic production lines. We have invested in the world’s most advanced solar PV module production line which has an annual production capacity of nearly 200MW. For the purpose of quality control, every working procedure is conducted under the very strict supervision of our professional inspectors.
The first step in the production process is to select high-quality crystalline-silicon solar cells carefully. Then these solar cells are classified and managed.
Next, we cut various components to clients specific requirements. The cutting equipment processes products in a precise and expedient manner, which provides a reliable guarantee on the quality of all products and production capacity.
The automatic welding machine connects crystalline-silicon solar cells in series and welds them together with the use of infrared heating technology. This is cutting-edge technology which operates at a maximum speed of 2,400 pieces per hour. This greatly enhances our production efficiency.
Laying is a process in which the series-connected encapsulation materials are arranged together according to design requirements.We strictly carry out the visual inspection of all components to ensure accuracy of production and avoid delays. Unqualified components will be picked out and repaired.Prior to lamination, our staff operates a special machine called electroluminescence tester which uses a high-definition camera to test photovoltaic modules.This machine clearly identifies the quality defects of solar cells, including crack, break and zero current, just to name a few, to ensure PV modules are compliant with quality standards before lamination.
The workshop is equipped with fully-automatic laminating equipment which heats PV modules at high temperature. A vacuum system is used to evacuate gas from the PV module, which results in a stronger bond among the EVA, solar cell, backsheet and the glass.The last step is to carry out visual inspection of laminated solar modules. Only carefully-selected and qualified products will be encapsulated to ensure safety. We test all modules in terms of power and electroluminescence before packaging. This helps to protect solar cells from imperceptible damage, and thus ensure all modules can generate electricity in an efficient and stable manner.
All raw materials we use are classified and arranged in an organized system. Those raw materials which require environmental protection are placed independently at constant temperature. We apply the first-in, first-out method to our company and the inspection of our raw materials occurs daily. The finished modules are sorted and placed in an orderly fashion, according to their specifications and models.
The workshop covers an area of 8,000 square meters. There are totally two fully automatic production lines and 9 laminating machine in it with an annual output of 200MW. All the workers in the production line operate strictly in accordance with requirements. Each process is supervised by professional quality control personnel on the spot.
The high quality crystalline silicon cells are sorted out and classified in the sorting process.
The back film, EVA, welding tape are cut according to the requirements.
The automatic string welding machine adopts the infrared heating technique to weld the crystalline silicon cells. The maximum output of the advanced string and welding machine is 2400 pieces per hour, which greatly raises the production efficiency.
Battery strings, glass, EVA, backplane, and other packaging materials will be installed together at their designed positions. The appearance of the solar modules will be inspected in order to pick out the unqualified products for repairs.
After being laminated by fully automatic lamination equipment, the photovoltaic modules will be heated in high temperature and the internal air will be evacuated by the vacuum system. These processes make the EVA, battery, back film, glass bond together.
Appearance inspection: The appearance of the laminated solar modules will be inspected in order to select qualified products for next step production.
The high-definition camera can clearly detect the quality problems of solar cells including subfissure, broken gate and no current. Thus, the photovoltaic module will reach the quality standard before lamination.
Insulation withstand voltage tester, ground continuity tester are used to monitor the performance of the product in order to guarantee the smooth installation.
The photovoltaic power classification conducted by the solar simulator ensures that each module purchased by the customer has positive tolerance.
The silicone curing:
After framing, the silicone curing will be conducted in an enclosed space by the large-scale humidification equipment.
Electroluminescent equipment for detection before packaging:
There will be final round of EL test before packaging to prevent the damages which cannot be detected by naked eye, and to ensure the stable power supply of each component.
The appearance of qualified solar modules will be inspected in order to pick out high quality solar photovoltaic components.
Pack the high quality solar photovoltaic components that have been picked out.
