The reliability of components is critical for investors or EPCs. Reliable components represent reliable cash flow for investors, and highly reliable components reduce operating costs for EPC.
The reliability test of components in the laboratory is still better than the harsh environmental challenges of the real world, but the specific accelerated aging test results of the components in the laboratory can be used to estimate how the component aging mechanism affects the performance output, and thus can understand the difference. The components are suitable for installation under those environmental conditions, thereby maintaining stable cash flow and saving operation and maintenance costs.
In 2018, DNV GL announced the Scoreboard results of the components. These data can be provided to investors or system vendors as a reference for selecting components. 2018 DNV GL selects four tests: TC600, DH2000, DML and PID, EnergyTrend describes the tests represented by Meaning and applicable environment:
In 2018, 22 manufacturers participated in the test. The components were manufactured in Asia and North America. The components tested were conventional single crystal and polycrystalline. There were not many component manufacturers in the four tests, which can adapt to high temperature and high humidity environment. The success rate of the DH2000 project is only 60%. For example, the JA Solar JAM60/PR series and the SunSpark SST series single crystal components have not passed the test. Among them, the component manufacturer Longji Leye, the single-chip component LR60 series all passed the test, representing its components. The reliability has reached the level, can adapt to a variety of environments, and can be used as a reference for components selected by the system.
In 2017, total shipments of monocrystalline modules were about 30%, regardless of the proportion or quantity, which is much larger than that of 2016. Although the global market is still dominated by polycrystalline, with the two major monocrystalline wafers leading factories in 2018 Large-scale layout of single crystals: including Longji 28GW and 23GW of medium-capacity production capacity. In 2018, the estimated annual production capacity of monocrystalline silicon can reach 60GW. In the first half of 2018, global component shipments reached about 60GW, and Chinese components came out. The cargo volume reached 42GW; the proportion of single crystal and polycrystalline in the Chinese market has come to 5:5. The market's willingness to purchase single crystals continues to increase with the change of atmosphere, and the supply capacity of the supply side is also released. It can meet the needs of the market. Longji Leye has been recognized by third-party testing as a supplier of high-quality, highly reliable components, which is clearly a reliable choice for downstream system vendors.
