210 x 210 cell solar module will become mainstream product

RENA solar panel machine company get a big order from an Asian solar panel compnay. It is the production line for manufacturing 210 solar module.

Many solar cell company start to produce 210 x 210 mm solar cell,

Before 2017. the solar cell production line can produce the solar cell lesss than 158.75 x 158.75mm; From 2017 to 2019, the solar cell production line can produce the solar cell size less than 166 x 166mm. In 2020, the new solar cell production line can produce solar cell size 210 x 210mm.

With the improvement of technology, the solar cell conversion efficiency is expected to reach more than 24%, and the corresponding component design optimization, load capacity improvement and advancement in downstream installation methods will continue to increase the power of the components.

According to reports, Trina Solar’s overall production capacity of 210 modules is about 10GW, and the production capacity will reach 21GW and 31GW at the end of 2021 and 2022 respectively.

High-power solar modules are based on multi-bus grid technology, adopt low-voltage, high-current design, and adopt advanced technical solutions such as non-destructive cutting and high-density packaging to significantly improve the performance of anti-cracking and hot spot resistance, and further reduce the system cost of components And the cost of electricity.

Through calculations, the low-voltage side cost of the three modules has decreased significantly with the increase in power. The 545Wp module with 210mm silicon wafer has the lowest overall cost under different latitude conditions, compared with the 166-type 445Wp module , The drop is between 0.1-0.17 yuan/watt; compared with the 182-type 535Wp module, the drop is between 3-7 minutes/watt.

According to a set of outdoor measured data of 166, 182, and 210 modules in September, under the condition of using a single small piece of 30% ratio, the 210 hot spot temperature is lower than 19℃ for 182, 166 modules, and large modules are relative to other floors in the market. Power station components have significantly excellent resistance to hot spots.

At the same time, because of the unique process, high power is ensured on the one hand, and the series resistance is appropriately increased to improve the low radiation performance.

The large components adopt the traditional short-side vertical two-layer stacking packaging method, and the utilization rate of standard containers is further improved relative to that of large components, delivering a more economical logistics solution for the terminal.
