800W(JA Solar), 780MW(Tongwei) and 660W(Trina Solar), the top 3 modules at SNEC 2020

The PV industry has recently witnessed the launch of a new wave of high-efficiency, high-power modules incorporating state-of-the-art technology. As China and other countries around the world embrace grid parity, modules with higher conversion efficiency and output are becoming increasingly favoured by the market.

Amid the accelerated push for higher efficiency and mounting cost pressure, major companies are competing with each other to produce larger modules connected by more cells.

Starting from 157.75mm, wafer sizes have gradually increased to 158.75mm, 161mm, 166mm, 182mm and 210mm. Zhonghuan Semiconductor carried it even further by launching a 217mm x 217mm wafer. On the cell side, the quantity has changed from 60 to 72, now followed by 78.

PV Tech visited a number of mainstream module companies at this year's SNEC exhibition in Shanghai to take a closer look at their products, all of which pointed to the fact that the industry has entered the 5.0 era of high-power modules (500W).

500W+ modules have already become mainstays of companies like Jinko Solar, Trina Solar, JA Solar, Risen Energy, LONGi Solar, Canadian Solar and GCL-SI, but 660W and even 800W modules were unveiled at the show.

One of the companies making such a statement was JA Solar, which exhibited its 800W ultra-high power module (810W), the highest power of all at the show. Meanwhile, perhaps more surprisingly, the second-highest power module (780W) came from Tongwei.

Trina Solar exhibited its 660W ultra-high power module just three weeks after the release of its previous 600W module. According to Trina, the 660W module, with optimised product design, was built upon the 600W version. At the same time Jinko Solar showcased its new generation, high-efficiency 610W Tiger Pro. The conversion efficiency of this eye-catching, tiling ribbon mono module can reach 22.3%.

Other manufacturers have also placed technology at the heart of development to jointly drive module power beyond 500W. The recent progress of the supply chain has been marked, given that it was only last year that the industry exceeded 400W and, less than one year later, it has jumped beyond 500W, exceeding 600W in some instances.

Talesun Solar, Jinergy and others also introduced new featured products at SNEC.
