Advanced component technologies, such as double-sided power generation components, shingle components, half-chip battery components and multi-main grid components, areTogether with high-efficiency battery technology, it contributes to improving the reliability and power generation efficiency of photovoltaic systems and reducing the cost of electricity. The double glass module replaces the back plate with photovoltaic glass, which has higher reliability, weather resistance and fire rating. With the maturity of double-glass component technology, the application of PERC, HJT or PERT double-sided batteries can realize double-sided power generation without significantly increasing the cost, and realize 10%-25% power generation gain at the system end. Due to the improvement of testing standards and testing equipment for double-sided components, as well as the recognition of the value of double-sided power generation by downstream power station enterprises, the winning bid of double-sided components in the 5GW application leader project in 2017 was about 2.58GW, accounting for 51.6 percent.
The battery is sliced and bonded together with conductive adhesive, and more than regular groups can be placed in the same component area.more than 13% of the battery. Therefore, the shingled component has the advantages of high output power, low internal loss and small hot spot effect. A large-scale ground power station project using the Syraffe tile component was connected to the grid in January 2018. In May 2018, Dongfang Huansheng released a new generation of high-efficiency stacking components, with a mass production efficiency of more than 20% and a component power of 335W.
The half-piece battery assembly connects the standard battery pairs in series, reduces the current mismatch loss, and reduces the power loss of the welding belt.75%, so the output power of the half-piece battery assembly can be increased by about 5-10W, and the hot spot temperature can be reduced by about 25 degrees C. Half-chip battery components are compatible with double-glass double-sided power generation, high-efficiency batteries and multi-main grid processes, and are expected to become a new generation of regular component technology. Jingao, Jingke, Artes, Hanwha Q Cells, REC Solar, Oriental Sunrise, GCL Integration, etc. have built GW-class half-chip battery module capacity.
Multi-master grid technology can reduce the shading area and reduce resistance loss, improve battery efficiency, and improve the optical of the welding belt area.Utilization to further increase component power output. The multi-main grid battery also has the advantages of low silver paste consumption and not easy to crack. The multi-main-gate cell metallization process and the interconnection process between the cell pieces are the key technology of the multi-main-gate assembly. The non-main-gate technology uses a round copper wire coated with a low-temperature alloy to replace the main gate, which also has the advantages of multi-main-gate technology.
The second double-glass double-sided, overlapping tile, half-piece and multi-main grid component forum 2018 will be held in Changzhou from August 2 to 3. WillThe meeting will discuss the prospect of global and Chinese photovoltaic market and the development trend of module technology, the technical advantages and return on investment of double-glass double-sided, shingled, half-piece and multi-main-grid modules, the demonstration experience of intelligent manufacturing of photovoltaic modules, the testing standards and equipment of double-sided modules, the key equipment of shingled, half-piece and multi-main-grid modules and the improvement of industrial production yield, and other advanced technologies and packaging materials to improve the power of components.

In the future, the installation cost of household distribution power stations will increase greatly, and there will not be so much profit, and the industry will have to be reshuffled.
