BloombergNEG's Tier 1 Module Suppliers

PV Module choice affects more than the datasheet numbers on a spec sheet.

Panel dimensions, frame tolerances, connector type and packaging all flow through into racking / tracker design, torque specs, installation sequencing and how modules move from delivery through to final electrical connection on site.

@BloombergNEF's Tier 1 classification tracks bankability rather than technical performance, but it remains one of the clearest signals of which module manufacturers are consistently supplying financed, utility-scale projects around the world. It's a useful reference point when thinking through supply chain reliability and project financing requirements.

10 of the leading names on the current Tier 1 list, ranked by annual production capacity:

@Jinko Solar

@LONGi

@Trina Solar

@JA Solar

@Tongwei Solar

@Canadian Solar

@Astronergy

@Risen Energy

@AIKO Solar

@TCL Zhonghuan

At Tranex Power, our mechanical and electrical delivery experience across a range of module types gives us a practical understanding of how these products perform once they leave the datasheet and hit the racking.
