DT Infrastructure (DTI) has granted TCL Solar a 720MW module supply contract for the Smoky Creek and Guthrie's Gap solar power stations in Central Queensland, Australia. The deal makes the combined sites the world’s largest utility‑scale deployment of back‑contact (BC) solar technology, accelerating the shift toward higher‑efficiency renewable power.

Key Takeaways

  • DTI signs a 720MW module supply contract with TCL Solar
  • Projects will use BC modules with up to 24.2% efficiency
  • Marks a milestone for large‑scale renewable energy in Australia

Project Overview

DT Infrastructure (DTI) announced that TCL Solar will supply modules for Edify Energy’s 720MW Smoky Creek and Guthrie’s Gap Solar Power Stations in Central Queensland. Installation is slated to begin in early Q2 2027, featuring Back Contact (BC) modules delivering up to 24.2% efficiency, a 30‑year performance warranty and a 15‑year product warranty.

Historical Background

Back‑contact technology was pioneered by SunPower in 1985 and has since set industry benchmarks for efficiency and reliability. Landmark projects such as California’s 579MW Solar Star (2015) and Australia’s 349MW Limondale Solar Farm (2021) demonstrated the scalability of BC modules, paving the way for today’s record‑size contract with TCL Solar.

Why This Matters

BozokMedia analysis shows that BC technology is moving beyond premium residential markets into utility‑scale applications, promising lower levelized cost of electricity (LCOE) and longer asset lifespans for investors.

"The combination of high module efficiency and long‑term warranties makes back‑contact panels a game‑changer for large renewable projects," says energy analyst Dr. Maya Patel.
Did You Know?: Once operational, Smoky Creek and Guthrie’s Gap will become the largest back‑contact solar installations globally, surpassing the previous record set by SunPower’s Solar Star.

Frequently Asked Questions

Question 1: What efficiency can be expected from the BC modules?
Answer: The modules are rated up to 24.2% efficiency, one of the highest figures available for commercial solar panels.

Question 2: When will the project start and how much energy will it generate annually?
Answer: Construction begins in early Q2 2027, and the combined stations are projected to produce about 1,589,000 MWh of renewable energy each year.
