Energy Taiwan 2019: PV technologies and trends in Taiwan market

The 2019 Energy Taiwan, which took place in Taipei on Oct. 16 through 18 this year, featured five major themes spanning solar PV, wind, hydrogen, fuel cells, and smart storage.

The Taiwanese government seeks to achieve 20 GW of cumulative solar installed capacity by 2025. This August, the aggregate installation stood at 3.7 GW, and it’s expected to reach 4 GW or even more by the end of the year. Estimated by PV InfoLink, Taiwan has 2.85 GW of existing manufacturing capacity. The capacity volume could help realize Taiwan’s solar energy goal, though the market saw a few developers starting using non-Taiwanese modules for projects.

During the solar energy summit held at the expo, a speaker suggested promoting solar through electric cooperative system in rural area. For example, the 40,000 hectares of land-based fish farms as well as abandoned or uncultivable lands in central and southern Taiwan could be used to install solar array. The Taiwan Sugar Corporation has recently offered 2,600 hectares of land for installing solar systems, and it’s estimated that the installation could reach 1.5 GW, added the speaker.

This year, companies mainly exhibited mono PERC modules, while a few displayed n-type HJT and TOPCon modules, such as URE and Motech Solar. Canadian Solar showcased cast-mono modules.

In terms of cell size, M2 wafer still dominates the Taiwanese market, though most manufacturers are now moving toward larger wafers. Overall, 158.75mm (G1) is the most widely adopted size, with 72-cell module having a power output of 400W or even more. It’s expected that G1 will become the mainstream size of larger wafer in Taiwan. A few manufacturers, including AUO, GINTUNG, URE, and Win Win Precision Technology, displayed modules using M4 or M6 wafer.

Exhibition Highlight – Half-Cut Module

Modules displayed at Energy Taiwan:

  • Half-cut module

Half-cut technique is apparently the most widely adopted module technology among Taiwanese manufacturers. All the large manufacturers exhibited half-cut modules this year, showing that the adoption of half-cut modules has improved, and it is expected to become mainstream from Q4 to the first half of 2020 in Taiwan.

  • Multi-busbar (MBB)

As modules coupling with half-cut technique can meet the requirement of Voluntary Product Certification (VPC), the market’s demand for MBB modules, which can generate higher output, is still low. This year, only Motech Solar and AUO displayed MBB modules.

  • High-density module

As for the much-discussed high-density modules, Energy Taiwan saw only a few this year due to low demand. URE, TSEC, and Win Win Precision Technology displayed paved modules with triangular ribbon, and the latter will mass produce paved modules next year. TSEC, Mega Sunergy and Wah Lee were the only three manufacturers that exhibited superposition welding modules.
