600W+ high-power modules have been fully industrialized and are becoming the mainstream of the photovoltaic industry. Through the joint efforts of the members of the 600W+ Photovoltaic Open Innovation Ecological Alliance, it has the characteristics of high power, high efficiency, high power generation and high reliability. PV InfoLink predicts that in 2022, the production capacity of 210 cells and modules will reach 309GW and 344GW respectively, while 600W+ will be fully adapted to 238 inverters from 22 mainstream inverter brands and 14 first-line tracking bracket brands. It can be seen from the calculation formula of the cost of electricity per kilowatt hour that reducing the initial investment of photovoltaic power plants and increasing the total power generation during the life cycle of the power station are the keys to reducing the cost of electricity per kilowatt hour of photovoltaic power generation.

Therefore, high-power and high-efficiency products can reduce the system BOS cost and reduce the initial investment of the project, and high-power and high-reliability solar module products can increase the total power generation of the power station project throughout the life cycle. That is to say, products with the characteristics of "four highs" can reduce the cost of photovoltaic power generation. In fact, lower cost of electricity has always been an important driving force for the continuous growth of photovoltaic installed capacity, and it is also the starting point and end point of technological innovation in the photovoltaic industry.

According to Bloomberg New Energy Finance, between 2010 and 2021, the global cost of electricity (LCOE) for large-scale photovoltaic power plants fell by an average of 84%. Specifically, the global weighted average total installed cost of PV projects in 2021 is $857/kWh, down 82% from 2010 and down 6% year-on-year. Among them, from 2010 to 2021, the global weighted average LCOE of centralized photovoltaic power plants decreased by 88%, from $0.417/kWh to $0.048/kWh.

In order to achieve the "four highs", the members of the 600W+ Ecological Alliance joined forces to overcome and solve problems related to crystal pulling, slicing, batteries, modules, product design, reliability, junction boxes, glass, inverters and tracking brackets. The solution of the above problems also guarantees the high reliability of 600W+ accordingly.

But can high-power, high-efficiency, and high-reliability module products achieve high power generation? In order to get the answer, TÜV Rheinland and CPVT China National Photovoltaic Quality Inspection Center conducted actual measurements on 600W+ modules at different latitudes, different temperatures and different irradiation conditions around the world. The results show that the measured power generation of the 210 module is higher than that of the reference module at high, medium and low latitudes, and the power generation is about 1.51%-2.1% higher.

In the high latitude region represented by Cologne, Germany, the test data in winter shows that the 210 Extreme 660W single-sided module has a 2.1% higher power generation per watt than the reference module.

In the mid-latitude region represented by Yinchuan, China, the 550W single-sided module has completed a year of outdoor measurement, and the power generation per watt is 1.51% higher than that of the reference module. Also in Yinchuan, China, during the test period from November 2021 to July this year, the power generation per watt of the 660W single-sided module was 1.9% higher than that of the reference module.

In winter and spring, the proportion of low irradiation is high, and the advantages of 600W+ modules are more obvious, and the power generation per watt is 2.5% higher than that of the reference module. Test data in low-latitude regions represented by Hainan, China in spring show that the power generation per watt of 660W single-sided modules is 1.6% higher than that of reference modules. According to the research and analysis of Fraunhofer ISE, an authoritative European institution, in the German ground power station scenario, the 670W module can save the system BOS cost by as much as 2.05Euro cents/W.

In addition, more than ten domestic and foreign authoritative institutions such as DNV, Latin American Enertis, North American Black&Veatch, and Xikan Research Institute have conducted extensive value analysis on 600W+ high-power modules on a global scale, covering 15 major application scenarios. Compared with the general 540W panel on the market, the 670W modules can save up to 6% of the BOS cost, and the corresponding LCOE can be reduced by up to 4.1%.

And in distributed application scenarios, the advantages of 600W+ modules are also obvious. For the photovoltaic end application market, the cost of electricity is absolutely important, and it is equally important to embrace more advanced productivity in the process of carbon neutrality. 600W+ ultra-high power solar panel is undoubtedly the best choice at present.
